Heiglit of body somewhat mori' than half the total length (without caudal) ; greatest 

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

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

 orbital arch with seven cavities; the bony ridges of the head terminating in several olimt 

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



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



This species was described from three specimens, 32 to 43 millimeters iu length, taken 

 from the stomach of an albicore, in 31° N. hit., 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'.

 dan, Cat. Fish. N. Amer., 1885, 24. — Gunther, Challenger Report, xxii, 25. 



Berycids with a laterally oval or broad pjTiform contour, a comjiressed body co^■ored 

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

 of very long, jwinted teeth in front of upper jaw closing in front of lower, a similar pair of 

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

 jaw two long teeth terminating in bulbous tips; a row of minute teeth on the posterior half 

 of the .supramaxillaries, and a toothless palate. 



This genus, closely related to Anoplo<iasier, is represented by a single Atlantic species. 

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

 manuscript by Dr. Gill: 



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

 converging to caiulal peduncle, which is moderately long and slender. 



Scales small and not or scarcely imbricated, upraised by peduncles, and with the sur- 

 face extended and dentate behind. 



Lateral line distinct and developed as a groove running parallel with the back and 

 continuous to the base of the caudal tin. 



Head higher than long, with the cranial portion very declivous, and with the suspen- 

 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 interinaxillaries and a median hastiform one behind; also with a 

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

 bony bars limiting the large muciferous cavities; suborbital bones enlarged, scu]])tured, and 

 with small, erect S])ines; the first with three radiating bars; the second largest, sending 

 four depending processes, three forward or downward, and another articulating with the 

 prc'oijerculum above its angle; the postorbital expanding distally ai:d articulating with the 

 ])reoi>erculum above; the interspaces covered by a tense skin with the extension of the scales 

 imbedded in it. 



Prcoperculum augulated downward and backward, spinigerous at the angle and with 

 no horizontal lines; opercular apparatus much reduced ; the operculum extended downward, 

 with numerous stria- and ridges and with three more diverging ridges extended backwards 

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

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

 pointed backward. 



The eye moderately developed near the anterior profile. Tpiier jaw not protractile, 

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

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