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

 angular 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 Albatross Station 2677, in 478 fathoms. The 

 types, two in number, measure 1H and 12 inches, respectively. Another 

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

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

Head 74; depth 9. D. X; A. XIX, 130; P. about 17; V. II, 9; B. 8; 

 scales about 20-400-36. Body much compressed, its greatest width about 

 i its height. Head everywhere covered with very small scales, its bones 

 very flexible, but protected by leathery skin. Interorbital width more 

 than length of snout, 4 in head, twice diameter of eye. Mandible twice

 der, blunt, close-set, and comb-like, 32 on each side ; teeth of lower jaw 

 shorter, slenderer, in 2 rows ; palatines with villiform teeth, in about 2 

 series. Distance from snout to dorsal 2f times length of head, its length 

 nearly twice length of head; anal beginning close behind vent, its length 

 half the body. Pectoral short and rounded, its length (uncertain) about 

 i the head. Ventrals broad, with peduncle-like bases thickly covered 

 with scales ; closely adjacent, separated by a narrow groove. Length 3

 taken from the stomach of a Somniosus microcephalus. (Qdcryavov, sword;

Body elongate, covered with minute, imbricated scales. Head scaly. 

 Mouth inferior. Dorsal fin represented by numerous short, straight, 

 robust, and disjointed spines, 27 to 35 in number, the first in advance of 

 the insertion of the pectoral. Anal as in Notacanthus, but lower and 

 with a longer portion of low, short, slightly curved, disjoined spines, 

 from 35 to 55 in number, which, under the final dorsal spines, pass into 

 flexible rays. Lateral line straight, conspicuous. Pectorals moderate, 

 placed far back, below the middle line of the body, and remote from the 

 lateral line. Teeth in jaws erect, small, and also in series on the vomer
