Height of body somewhat more than half the total length (without caudal); greatest 

 width a little more or less than half its lieight. Head a little more than one-third of total. 

 Eye nearly one-third of head; iuterorbital width nearly one half that of the head. Sub- 

 orbital areh with seven cavities; the bony ridges of the head terminating in several oluut 

 points. Veutrals midway between tip of snout and base of caudal. 



Eadial formula: D. 17; A. 9-10; P. 16; V. 7. 



This species was described fi'om three .specimens, 32 to 43 millimeters in length, taken 

 from the stomach of an albicore, in 31° N. lat., 40^ W. Ion. Another, 77 millimeters long, 

 was taken from the stomach of some other pelagic fish, in 25° N. lat., 31° W. Ion. 



A specimen was obtained by the Albatross, in N. lat. 39° 18' 30", W. Ion. 68° 24'.

Berycids with a laterally oval or broad pyriform contour, a compres.sed body covered 

 with small, pedunculated, leaf like scales, an abruptly declivous forehead, small eyes, a pair 

 of very long, pointed teeth in front of ujjjjer jaw closing in front of lower, a similar pair of 

 still longer pointed teeth in the lower, received in fovea' of tlic palate; on the sides of each 

 jaw two long teeth terminating in bulbous tips; a row of minute teeth on the iwsterior lialf 

 of the supramaxillaries, and a toothless palate. 



This genus, closely related to Anophxiaster, is represented by a single Atlantic siiecies. 

 The details of its structure are described more fully in the following notes communicated in 

 manuscript by Dr. Gill : 



Body compressed, pyriform, highest in front, and with the dorsal and inferior outlines 

 converging to caucbil peduncle, which is niodei-atcly long and slendei-. 



Scales small ;uid nut or .scarcely imbricated, upraised bj- peduncles, and with the snr 

 face extended and dentate behind. 



Lateral line distinct and developed as a groove running jiarallel with the back ;iud 

 continuous to the base of the caudal fin. 



Head higher than long, with the cranial portion very declivous, and with the su.spen- 

 sorial portion obliquely extended downwards and backwards; the cranium above with three 

 naked membranous areas, an anterior pair pointed forward and diverging to receive the 

 ascending process of the intermaxillaries and a median hastiform one behind; also with a 

 naked horseshoe-shaiied area around the nape; the naked spaces being separated by the 

 bony bars limiting the large muciferous cavities; snboibital bones enlarged, s(uli)tuied, and 

 with small, erect s])iues; the first with three radiating bars; the .second largest, sending 

 four depending proces.ses, three forward or downward, and another articulating with the 

 preoperculum above its angle; the postorbital expanding distallyand articulating with the 

 preoi)erculum above; the interspaces covered by a tense skin with the extension of the scales 

 imbedded in it. 



Preoperculum angulated downward and backward, spinigerous at the angle and with 

 no horizontal lines; o])ercular apparatus much rednced : the operculum extended downward, 

 with luinierous stria- aiul ridges and with three more diverging ridges extended backwards 

 or downward into spiniform angles, one horizontal and the others oblique, leaving emar- 

 ginated interspaces between; the inter- and subopercula small, the latter with several stria- 

 pointed backward. 



The eye moderately developed near the anterior profile. Upper jaw not protra<ti]e, 

 with the intermaxillaries extended far backward and the supramaxillaries lying behind and 

 above, and with wide oval extremities furnished with radiating ridges or stria-.
