the front of the pupil) is about equal to the orbital diameter, being 

 contained 1.6 (1.3 to 1.5) times in the postorbital. The least sub- 

 orbital width is contained 3.1 times in the postorbital (2.9 to 3.2 

 times in paratypes from 60 to 77 mm. to anus; 2.7 to 2.85 times in 

 paratypes from 50 to 57 mm. to anus). The upper jaw extends from 

 below the middle of the nasal fossa backward nearly to the vertical 

 from the posterior margin of the orbit; length of upper jaw, 3.3 

 (3.4 to 3.7) in head. The barbel is slender; its free length is con- 

 tained 2.6 (2.3 to 3.3) times in the postorbital. 



The cardiform teeth of the upper jaw form a band, the outer series 

 of which is sometimes enlarged. The mandibular teeth form two 

 series laterally, of which the outer series is irregular; anteriorly, 

 near the symphysis, the teeth are so irregularly arranged as to form 

 a narrow band.

The characters of the sensory canals and of the structures con- 

 nected with them, are essentially similar to those described for C. 

 argentatus. 



The anus is located immediately before the anal fin; the distance 

 from its center to the base of the outer ventral ray is contained 2.4 

 (2.5 to 3.2) times in the head; its distance from the isthmus, 1.32 (1.4 

 to 1.6) times. The distance between, the base of the ventral and 

 the isthmus is contained 2.8 (2.85 to 3.27) times in the head. 



The gland-like body lying in the body wall, along the midventral 

 line, has the peculiar structure that it also possesses in the last 

 species — the anterior dilation is supported by a slender rod connected 

 with the pubic bone. 



P3doric caeca, 8 to 11 (4 specimens) . 



Several specimens contained Crustacea of various groups in their 

 stomachs, but one contained a Myctophid fish, probably Myctoplmm, 

 belonging to the silvery pigmented or surface-pelagic type. 



The lateral line rises anteriorly to form a long, even curve. The 

 scales are relatively large, in but four rows between the lateral line
