308 DEEP SEA FISHES. 



General color dark olivaceous ; fins with black edges that widen back- 

 ward ; lateral line lighter, pores whitish ; pectoral fins yellowish toward the 

 outer extremity ; linings of the branchial chamber black, those of the 

 mouth and of the abdomen blackish. This coloration differs from that of 

 Gilbert's specimen in having no white margin to dorsal and anal ; it may be 

 tliat the two forms do not belong in the same species. 



CoxGROSOJiA gen. n. 



Body elongate, compressed, caudal portion much the longer. Head 

 small, shorter than the trunk. Snout short, thick, blunt. Eyes large, 

 lateral; pupil round. Mouth medium, cleft below more than half the eye. 

 Teeth small, subconical, subequal, in broad bands of which those on the 

 iipper jaws and the vomerines are not separated in front. Lips well devel- 

 oped. Vertical fins continuous; caudal small; dorsal origin at a distance 

 behind the bases of the pectorals. Lateral system strongly developed on 

 body and head; pores large. Vent far in advance of the mid length.
