General outlines of the type, a male of about 33^ inches, from the Sagami 

 Sea, Japan, resembling those of a large specimen of Squalus acanthias. The 

 mouth, teeth, scales, spiracles, and fins are those of that genus. The positions 

 of the fins recall those in S. acanthias, but the dorsals are larger, more nearly 

 alike in size and more nearly equal to the pectorals and the ventrals. Head 

 large, depressed. Spiracle large, near the eye. Mouth moderate, in a low arch. 

 Teeth H, alike in the two jaws. Gill openings medium, in front of the pectorals. 

 Snout rather short, blunt; nostrils about midway from mouth to end, anterior 

 valve with a slender, pointed barbel (nearly ll inches long) on the inner end. 

 Hind margins of the dorsals and pectorals concave. Subcaudal lobe moderate; 

 no notch between subcaudal and terminal; no pit at the origins of the caudals. 

 Dorsal origin opposite the inner angles of the pectorals; origin of second dorsal 

 opposite the axils of the ventrals ; first dorsal spine about three fourths as high as 

 its fin; second dorsal spine about equal the height of the fin. Clasper of the male 

 short, thick, obliquely pointed. 



The possession of a narial barbel appears to be the character that must be 

 depended on for the characterization of Cirrhigaleus as a subgenus of Squalus. 

 In the type as figured the nostrils are placed close to the end of the snout, fig. 

 156; on fig. 158 they are seen to be about half way from the mouth to the end, 

 which is probably more nearly in accord with the specimen.
