A single specimen 10 inches long, from Station 2990, in 112 fathoms 



75. Leptophidium emmelas sp. nov.

 and slender, the longest half pupil, eight or nine movable ones developed. 

 Skull and all bones of head very thin and papery. 



Dorsal beginning over base of pectorals, the nape midway between 

 its origin and middle of orbit. Distance from snout to origin of anal 1^ 

 in distance from latter to end of tail. Pectorals half length of head. 

 Ventral filament 2f in head. 



Scales large, eight between lateral line and front of dorsal, covering

76. Otophidium galeoides sp. nov. 



Closely related to 0. taylori and 0. in^efatigaUle, differing from both 

 in color, from the former in gill rakers, and from the latter in the much

 insertion of dorsal, and the absence of spines on head.
