“Omnes res creatie sunt divine sapientix et potenti testes, divitie felicitatis human :—ex harum usu donifas Creatoris; ex pulchritudine sapientia Domini ; ex ceconomid in conseryatione, proportione, renovatione, potentia majestatis elucet. Earum itaque indagatio ab hominibus sibi relictis semper sestimata ; 4 veré eruditis et sapientibus semper exculta; malé doctis et barbaris semper inimica fuit.”—Linnaus.

“Quel que soit le principe de la vie animale, il me faut qu’ouvrir les yeux pour voir quelle est le chef-d’ceuvre de la Toute-puissance, et le but auquel se rappor- tent toutes ses opérations.”—Bruckner, Théorie du Systeme Animal, Leyden, 1767.

eee ee ee ee es» Lhesylvan powers Obey our summons; from their deepest dells The Dryads come, and throw their garlands wild And odorous branches at our feet; the Nymphs That press with nimble step the mountain-thyme And purple heath-flower come not empty-handed, But seatter round ten thousand forms minute Of velvet moss or lichen, torn from rock Or rifted oak or cavern deep: the Naiads too Quit their loved native stream, from whose smooth faes They crop the lily, and each sedge and rush That drinks the rippling tide: the frozen poles, Where peril waits the bold adyenturer’s tread, The burning sands of Borneo and Cayenne, All, all to us unlock their secret stores And pay their cheerful tribute. J. Taytor, Norwich, 188,

I.—The Anatomy and Classification of the Teleostean Fishes of the Orders Berycomorphi and Xenoberyces. By C. Tate Reaan, M.A.

(Published by permission of the Trustees of the British Museum.)

[Plate I.]

THe Berycomorphous fishes are a group of considerable interest, for on the one hand they approach the Perches in general structure, and on the other they retain many features of generalization which indicate their relationship to primitive Clupeoids.

The order was well represented in Cretaceous times, and the fossil genera were included in the fourth volume of Dr. Smith Woodward’s Catalogue of Fossil Fishes,’ issued in 1901. The best descriptions and figures of the extinct species are those of W. von der Marck (Paleont. xi. 1863) and of Smith Woodward (Paleontogr. Soc. 1902). Dr. E. C. Starks has given a useful account of the osteology of some of the recent types, with figures of the crania of Polymizia, Beryx, Hoplostethus, Monocentris, and Holo- cenirus (Proc. U.S. Nat. Mus. xxvii. 1904) ; I fully agree with him that the Pempheridze do not pertain to this order, but to the Percomorphi. The skeleton of Holocentrus has been figured by Agassiz (Poiss. Foss. vol. iv.) and that of Beryx by Giinther (‘ Challenger’ Deep-sea Fishes).

Ann. & Mag. N. Hist. Ser. 8. Vol. vii. i

2 Mr. C. T. Regan on the Anatomy and

In the following account both recent and extinct forms are dealt with, and the more important characters of the order and its component families are set forth; three families, Berycopsidee, Diretmide, and Anomalopide, hitherto regarded as of uncertain affinities, are assigned a definite place in the system, and the Melamphaide, until now included in the Berycide, are rejected from the order.


Parietals separated by the supraoccipital; nasals large, posteriorly attached to the frontals; opisthotic well-deve- loped, bounded in front by the pro-otic and below by the exoccipital; orbitosphenoid present, united by suture with the alisphenoids, but well separated from the mesethmoid ; a Y-shaped basisphenoid present; a thin-walled auditory bulla, containing a large otolith, formed by the pro-otic, parasphenoid, basi-occipital, exoccipital, and sometimes the opisthotic. Mouth bordered above by the protractile pre- maxillaries ; maxillary articulated with the vomer and attached near its proximal end to the well-developed maxil- lary process of the palatine; one or two supramaxillaries ; lower jaw of dentary, articulare and angulare. First pharyngo- branchial suspensory ; third and fourth ankylosed; lower pharyngeals separate ; three ossified basi-branchials. 4 gills; pseudobranchie ; 7 to 9 branchiostegals. Hyo-palatine and opercular bones normally developed. Vertebral column of solid centra which are co-ossified with the arches ; anterior ribs sessile ; posterior ribs on parapophyses ; hypurals more or less fused and expanded; three epurals (epaxial basalia) and two uroneurals. Post-temporal forked, attached to the eplotic and opisthotic ; usually two post-cleithra on each side ; no mesocoracoid ; pectoral radials four, hourglass-shaped, only the lowest in contact with the hypocoracoid. Air- bladder without pneumatic duct *. Anterior rays of vertical fins spinous ; pelvic fins thoracic or subabdominal, with or without spine and with from 3 to 13 soft rays; caudal fin typically with 19 principal rays, 17 of which are branched (18, with 16 branched, in the Polymixiide).

Family 1. Polymixiide.

Dorsal and anal fins long or moderately elongate, with a few graduated spines and rather numerous soft rays; caudal

with 16 branched rays; pelvics subabdominal, 7 or 8 rayed, without spine. Jaws with villiform teeth in bands; teeth on parasphenoid, vomer, palatines, pterygoids, and meso- pterygoids. A pair of hyoid barbels. Upper edge of maxillary slipping under the preorbital and anterior sub- orbitals ; two supramaxillaries, the posterior not overlapping the anterior ; all the suborbitals forming a subocular shelf ; nasals moderately large, separated in front by the premaxillary

In addition to the recent Polymizia, Lowe, the Cretaceous Platycormus, W. von der Marck, may be placed in_ this family; it has been well described and figured, and shows many important resemblances to the recent genus. ‘The less satisfactorily known Omosoma, Costa, and Pycnosterina, Heck., may be provisionally associated with Platycormus.

Family 2. Berycopside.

Berycopsis elegans, Dixon, from the Chalk of Sussex and Kent, has been fully described and figured by Dr. Smith Woodward. Itis in some respects intermediate between the Polymixiide and Berycide, but is well distinguished from both.

Dorsal and anal fins as in the Polymixiide ; pelvic fins not well known, perhaps as in the Polymixiide; two supra- maxillaries formed as in Berya, the posterior large and sending forward a pointed process above the anterior ; ptery- goid teeth present; occipital and parietal crests terminating above the middle of the orbit; suborbitals narrow, preorbital deep, and maxillary exposed; vertebra at least 26 and per- haps as many as 30.

Family 3. Berycide.

Dorsal and anal with a few graduated spines ; caudal with 17 branched rays; pelvics thoracic, of a spine and 7 to 13 soft rays. Jaws with villiform teeth in bands; teeth on vomer and palatines. Upper edge of maxillary slipping under preorbital and anterior suborbitals ; two supra- maxillaries, the posterior sending forward a pointed process above the anterior; subocular shelf formed by several sub- orbitals, or at least extending the whole length of the second ; nasals moderately large, separated by the premaxillary pro- cesses, but nearly meeting above them anteriorly; supra- occipital and parietals not overlapped by the frontals, with prominent crests which extend forward on the latter to the interorbital region; frontals anteriorly with prominent ridges bordering mucus cavities; alisphenoids united by suture. Hypocoracoids not narrowed forward, reaching the ventral profile and forming a symphysis behind that of the cleithra; pelvic bones embraced by the hypocoracoids and attached to the cleithra above the symphysis. Vertebra 24; no upturned centra, and the anterior uroneural ankylosed with the last centrum.

There are two very distinct genera, viz., Beryz, Cuv., and Hoplopteryx, Agass. ‘The former, with species from the

Classification of some Telcostean Fishes. 5

North Atlantic and Japan, has the dorsal, with IV 13-19 vays, much shorter than the anal, which has III-lV 26-30; the pelvics have I 10-13 iays. The latter includes three recent species from South Australia and New Zealand, in which the dorsal, with VI-VII 12-14 rays, is longer than the anal, which has IV 12-15, whilst the pelvics have I 7 rays. Moreover, the spines are stouter than in Beryz, and the scales are larger and structurally different, being slightly rugose with strongly pectinated edges, instead ot covered with little spines. There are several Cretaceous species of Hoplopteryx ; in the Australian H. affinis, Guiuth., the crests and ridges on the head are arranged exactly as in the Cretaceous H. lewisiensis described and figured by Dr. Smith Woodward. I give a figure of H. affinis, for comparison with the extinct forms (PI. I.).

Family 4. Diretmide.

The type of Diretmus argenteus, Johnson, ia in the British Museum collection ; it is evidently related to the Berycida. The dorsal and anal fins appear to be formed mainly of articulated rays, and probably not more than 3 or 4 are spinous ; the caudal has 17 branched rays ; each pelvic fin is composed of a laminar, oblong ovate, obliquely striated spine and 5 branched rays; (the pelvic spine of Berys is obliquely striated). The scales are small, adherent, spinulose, differing from those of Beryw in that the bases of the spinules are expanded into parallel vertical ridges.

The jaws have narrow bands of villiform teeth, witha series of larger pointed teeth in the lower; the palate is toothless.

The single large supramaxillary -has the form of the posterior supramaxillary of the Berycide ; the nasals are separated by the premaxillary processes; the subocular shelf and the alisphenoids and orbitosphenoids are as in the Berycide. The cranial crests and ridges are as in the Bery- cidee, except that the paired ridges which converge forward from the parietal crests in the latter are now united to form a single median ridge, owing to the narrowness of the inter- orbital region. ‘The thin-walled auditory bulla containing a large otolith can be seen above the gills. The pelvic bones are embraced by the enormously expanded hypocoracoids, which meet in a long symphysis ; this is an exaggeration of the Berycid condition.

Family 5. Trachichthyide.

Dorsal and anal spines few; pelvic fins thoracic, of a spine and 6 soft rays. Jaws and dentition as in the Berycida, but

vomerine teeth sometimes absent and anterior supramaxillary wanting; a single large supramaxillary, superiorly sending forward a pointed process ; subocular shelf a small or slender process of the second suborbital ; nasals very large, united by suture throughout their length, covering the ethmoid and the premaxillary processes. Frontals, parietals, and supra- occipital, with their ridges and crests, arranged much as in the Berycida. Alisphenoids separate, bridged by the orbito- sphenoid. Hypocoracoids narrowed forward below, not reaching the ventral profile, not embracing the pelvic bones, which are firmly attached to the cleithra above the symphysis. 26 vertebre ; no upturned centra, and the anterior uroneural alkylosed with the last centrum. Abdomen with a median seiies of ridged or serrated scales,

Recent genera are Trachichthys, Shaw, Hoplostethus, Cuv. & Val., Peratrachichthys, Waite, and Gephyroberyx, Bouleng. ‘Lhe Cretaceous Aipichthys, Steind., and Acrogaster, Agass., may be provisionally referred to this family. Sphenocephalus, Agass., shows some resemblance to Tirachichthys, but does not seem to have the abdominal series of ridged scales.

Family 6. Monocentride.

Differs from the preceding only in the large, bony, rigidly united scales, the absence of the first four ribs, and the reduc- tion of the pelvic fin to a spine and 8 soft rays. The trunk- muscles are inserted only on the posterior surface of the skull, and on the upper surface the occipital and parietal crests are converted into ridges bordering mucous channels.

One genus, MJonocentris, Bl. Schn.

Family 7. Anomalopide.

Differs from the Trachichthyide in the absence of mucous channels on the head and in the presence of a peculiar evertible subocular luminous organ.

There is a single example of Anomalops katoptron, Bleek., in the British Museum, and I have ascertained that the nasal bones, the orbitosphenoid, and the supramaxillary are as in the Trachichthyide. ‘There is a median abdominal series of ridged scales and the caudal fin has 17 branched rays. In this specimen the right pelvic fin is absent and the left has only 4 rays; these fins are said to be normally 6-rayed, but authors disagree as to whether the outer ray is spinous or

articulated. Protoblepharon palpebratus, Bodd., which has

been figured by Max Weber (‘ Siboga’ Exped. p. 109, 1902)

seems to have I 6 pelvic rays, and is otherwise very similar to Hoplostethus or Trachichthys.

Family 8. Holocentride.

A long spinous dorsal; anal with 4 spines; caudal with 17 branched rays; pelvics thoracic, of a spine and 5 to 8 soft rays. Jaws and dentition as in the Berycide ; two supra- maxillaries, the posterior large and sending forward a pointed process above the small anterior one ; subocular shelf formed by several suborbitals; nasals moderate, separated by the premaxillary processes, not convergent anteriorly ; a second nasal bone on each side below the nostrils. Frontals large,

overlapping the parietals and supra-occipital, which scarcely appear on the dorsal surface of the cranium; no parietal crests; occipital crest not extending on to the frontals, which have a pair of low longitudinal ridges bordering a median groove or channel, and posteriorly a varying number of ridges radiating backwards; trunk-muscles inserted only on poste- rior surface of skull, excavating large posterior temporal fossee, which are roofed by the frontals. Hypocoracoids narrowed forward below, not reaching the ventral profile, not embracing the pelvic bones, which are loosely attached by ligament above the symphysis of the cleithra, Vertebrae 26 or 27; no upturned centra, and the anterior uroneural anky- losed with the last centrum.

8 On the Anatomy &c. of some Teleostean Fishes.

Recent genera are Adioryx, Starks (‘Science,’ xxviii. 1908, p. 614), Holocentrus, Scopoli, Myriprist’s, Cuv. (with toothed maxillary), and Ostichthys, Langsdorff. The Creta- ceous Homonotus, Dixon, seems to be near Myripristis ; the fish described by Dr. Smith Woodward from the Chalk of Kent under the name Trachithyioides ornatus is known only from the skull, which is very similar to that of some recent species of Myripristis, although none of them show the principal frontal ridges quite so far apart posteriorly nor the radiating ridges so few. Dinopteryx, A. 8. Woodward, with seven anal spines, may be provisionally placed in this family.

I propese the new generic name Caproberyx for the fish from the Chalk of Kent described by Dr. Smith Woodward under the name Berycopsis major (Paleontogr. Soc. 1902, p- 11, pl. ii. fig. 2). Of the vertical fins only the anal spines are known, but the head and pectoral arch are well preserved and indicate relationship to the Holocentride. In the short premaxillary processes and the absence of a preopercular spine Caproberyx resembles Myripristis, in the expanded pre- orbital and the weak principal and numerous radiating frontal ridges Holocentrus. Bnt it differs from both in the greater prominence of the occipital crest, which bas the upper edge thickened and longitudinally ridged; in this and in some other features it shows considerable similarity to Antigonia, and it may be that this resemblance is due to real affinity and that Caproberyx is nearest of all the Berycoids to the Zeomorphi.

The Berycomorphi as above restricted do not include the Stephanoberycidze and Melamphaide. ‘These are probably derived from the same stock as the Berycomorphous fishes, resembling them in the structure of the protractile mouth, and in the caudal fin, which has
