Type.—lSio. 49802, U.S.^M.; Albatross Station 3773, Matsushimae 

 Bay, Japan; depth 78 fathoms. Length 113+ mm. 



Distribution. — Okhotsk Sea, Japan Sea, and Matsushimae Bay, 

 Japan, depth 70-200 fathoms. Eight specimens examined, the 

 largest 221 mm. 



RelatiojisMps. — C. matsushimae resembles CrystallicMhys mirabilis 

 in the cleft snout, shape of head and body, and the coloration; 

 differing mainly in the presence of barbels and the character of the 

 pupil.

 THE genus. Type 



about 18 in the half of each jaw. Snout distorted; jaws equal. The 

 following description of the snout and barbels is taken from two 

 specimens from Albatross Station 4855, Japan Sea. Snout projecting 

 beyond the upper lip for the diameter of the orbit. Barbels on each 

 side of the snout as follows : One in front of the upper snout pore and 

 at the tip of the snout; sometunes a second lateral to and separated 

 from the former barbel by the anterior pore on the snout; three on the 

 lower anterior surface of the snout between the maxillary pores, 

 separated from those on the other side of the snout by the stiff 

 vertical fold terminating and dividing the lower surface of snout. 

 The upper lip with three and sometimes five short barbels. Lower 

 lip with a median and two lateral barbels on each side, separated by 

 the mandibular pores; sometimes a second series of two behind the 

 first series. The longest barbel on the snout equals the eye; the 

 barbels on the chin equal to half the eye. The upper lip and lower 

 surface of snout divided, a stiff vertical fold of skin projecting from 

 the base of the cleft, as in CrystallicMhys mirabilis. Nostril in a
