306 DEEP SEA FISHES. 



half times as long as the eye. Nostrils medium ; anterior forward of the 

 mouth on the lower half of the snout, with a short tube; posterior at a short 

 distance in front of the middle of the eye, with raised edges. Mouth large, 

 cleft extending below little more than half of the eye ; lower jaw shorter. 

 Teeth small, in villiform bands of medium width ; those on the head of the 

 vomer are forward of the lower jaws and slightly separated from those of the 

 shaft, which latter are stouter, arranged in about four irregular series, sepa- 

 rated from those of the jaws, and disappear at a vertical from the posterior 

 nostril. The pores around the mouth and on the snout are of medium size. 

 Eye large, two thirds as long as the snout, one seventh of the lengtli of the 

 head, length greater than the width of the gill openings or less than their 

 distance apart. Interorbital space two thirds of the orbital length. Bran- 

 chial apertures extending up forward of the lower half of the base of the 

 pectorals. Lateral line distinct, with a series of large pores along its lower 

 edge, and with a series of minute pores near the middle, each pore of which 

 is a trifle backward from one of the large ones. 



Vertical fins continuous around the tail. Dorsal better developed than 

 the anal, its origin forward of the pectoral bases about one half of the orbital 

 length. Anal rays short, first below the sixty-second ray of the dorsal. 

 Caudal pedicel muscular and deep, fin rounded on the hind margin. One of 

 the specimens studied has but fifteen caudal rays, which appears to be nor- 

 mal ; another has thirty-three rays in the fin, but in this case a space 

 covered by membrane exists between them and the rays of the anal, which 

 fin contains fewer rays tlian on others. Total length thirteen and one 

 half, snout to anal origin five and one half, head two and seven eighths 

 inches and depth at the shoulders one inch. 



Body rusty brown, darkening toward the bases of the fins ; fins growing 

 lighter toward their margins; snout and lips lighter; lower and hinder por- 

 tions of the pectorals broadly margined with whitish ; linings of the branchial 

 chamber and of the abdomen black. On other specimens the fins grow 

 darker toward the caudal and the belly and opercular regions are very 

 dark. 



Allied to C. niiens, but differing slightly in proportions, having a shorter 

 broader pectoral, no black margin on the fins, no spots or dots, no silvery 

 shade, and no lighter color on the belly.
