168 DEEP-SEA FISHES OF THE ATLANTIC BASIN. 



upon head. Number of scales in lateral line not far from 400 (in the. partially digested 

 specimen before me it is impossible to make an exact enumeration). Number between 

 lateral line and dorsal fin about i'0, between lateral line and anal fin about 36. Head 

 covered in every part, even the lips, with small scales, of which there are about 40 betweeu 

 eye and end of opercular flap. Scales deeply imbedded (iu life probably hidden beneath 

 a slimy epidermis). 



Length of the head about 74, times in that of body. The bones are flexible, and their out- 

 lines are invisible without dissection, the whole being covered with a leathery skin. Width 

 of interorbital space appeals to be (in the mutilated head) somewhat greater than length of 

 snout, and about one-fourth length of the head. Diameter of orbit appears to be about 

 one-half width of interorbital space. Length of postorbital portion of head nearly 3 times 

 that of snout. Length of mandibular bone slightly exceeds twice diameter of eye; that 

 of upper jaw considerably greater. Teeth in upper jaw blunt, accicular, set side by side 

 like the teeth of a comb, about 32 on each side. In lower jaw shorter, slenderer, and in 

 double rows. Yilliform teeth upon palatines. 



Dorsal fin begins at a distance from snout not far from 2% times length of the head, 

 and nearly over the one hundred and tenth scale of lateral line; it consists of 10 low, widely 

 separated spines, unconnected by any membrane. Distance between first and tenth spine 

 nearly double length of head. 



Spines from fourth to ninth about equidistant, while other interspaces are shorter. 



Distance from snout to anal fin equal to about four times length of head. Anterior 

 spinous portion of anal resembles dorsal and is devoid of connecting membrane. (The 

 membrane is also absent from the posterior half of the fin, but may possibly have been 

 destroyed. Anal rays extend to tip of tail and number about 130, the number of spines 

 being 19. Anal begins immediately behind vent, and its length of base is slightly less than 

 half that of body (less by a length about equal to the distance from the angle of the mouth 

 to the gill-opening). 



Pectoral fin placed at a distance behind the gill-opening about equal to width of its 

 own base. (Its length is at least double this distance — how much, more can not be deter- 

 mined, but the fin is evidently short and rounded in contour, the upper rays longest). Its 

 base is stout, peduncular, and thickly covered with scales. 



Distance of the ventrals from snout equal to that of the dorsal, though its insertion is 

 slightly in advance of that of dorsal. Ventrals closely adjacent, separated by narrow 

 groove, broad, with peduncle-like bases, thickly covered with scales and provided witt 

 two spines and eight or nine rays (as nearly as the specimen will permit determination).
