Description of a female 332 mm. long to base of caudal, from Alba- 

 tross station 5011. 



Head, 0.293 of this length; depth, 0.38; dorsal, 85; anal, 64; pores 

 in the lateral line, 92. 



Outline of the head uneven, the dorsal outline sharply angulated 

 at both ends of the mandible; eyes about equal, their anterior borders 

 on about the same vertical; diameter of upper eye 0.05; interorbital 

 moderate and with a fairly straight ridge, extending from the anterior 

 border of the preorbital to the posterior edge of the preopercle; inter- 

 orbital with about three rows of ctenoid scales; anterior nostril in 

 a tube, the posterior with the margin slightly elevated; length of 

 snout from upper orbit, 0.05; snout with a strong curve above, 

 naked except on anterior margin of orbits; maxillary strongly curved, 

 extending past middle of eye, that of the blind side the longer, its 

 length 0.147, that of the eyed side 0.125; premaxillary unusually 

 broad and produced forward, more so than in any other species of 

 the genus; preorbital broad, covering the maxillary, in some speci- 

 mens nearly covering premaxillary; teeth uniserial, acute, conic, 

 directed backward, about four premaxillary canines on each side of 

 the jaw, irregularly arranged; behind the canines the teeth are smaller, 

 and are better developed on the blind than on the eyed side; several 

 canines on mandibular symphysis, decreasing in size posteriorly, 

 similarly enlarged on both sides; gill-rakers slender, 3 + 13 on the

 peduncle 0.10; length of caudal peduncle (from posterior end of anal),

 including the hypural plate. 



Scales of both sides ctenoid, rougher posteriorly than anteriorly. 

 Lateral line of both sides with a high curve, its length 0.19, its height
