anal ; dorsal spines distant from each other, and behind each is a narrow 

 anguhir membrane; anal beginning immediately behind vent, and in its 

 middle portion considerably elevated ; length of its longest rays about 

 equal to snout, from which point it slopes rapidly to tip of tail. Pectoral 

 placed high up in axis of body, inserted at some distance behind gill 

 openings, broad and nearly oval in shape ; ventrals confluent, some dis- 

 tance in advance of vent; stout, broad, ovate in form, not extending to 

 vent, but separated from it by a distance equal to half their own length. 

 Color, uniform light brown. This description is from the types of Gill, 

 (Type, No. 37856), from AIbairos>< Station 2677, in 478 fathoms. The 

 types, two in number, measure lU and 12i inches, respectively. Another 

 specimen, (No. 44246, U. S. N. M.) was obtained by the Albatross from 

 station 2676, at a depth of 407 fathoms, (nnalis, pertaining to the anal fin. )
