Eumycterias bitgeniatus Jenkins, new species. Fig. 12. 
Head 2.66 in length of body; depth a little greater than head. Back compressed, culminating 
in a very obtuse point above middle of pectoral fin. Profile from tip of snout to before eyes somewhat 
concave; straight from interorbital to top of dorsal prominence, descending in a straight line from 
here to base of caudal fin, being interrupted, however, at middle by elevation bearing dorsal fin. 
Ventral outline evenly curved, no more convex than the dorsal. Eye 3.33 in head. Snout 1.75 in 
head. Interorbital concave, slightly greater than eye, 3 in head. One nostril in each side, each a 
simple opening with slightly raised margin, but scarcely tubular. Distance from eye to nostril 2 in

distance from nostril to tip of snout. Front of dorsal fin midway between dorsal prominence and base of 
caudal fin, outline rounded; rays 10, longest 1.5 in snout. Caudal slightly rounded, median rays equal 
distance from tip of snout to center of pupil. Anal similar to dorsal, front of its base below posterior 
end of base of dorsal. Pectoral broad (in specimen median and lower rays on both sides broken), 
upper rays 2.5 in head. A few minute spines on lower surface of body; surface otherwise smooth. 
Color in alcohol: General color brown or dusky above, paler brownish below; a wide dusky band 
from base of upper rays of the caudal running forward along side of body, above base of pectoral, to 
upper end of gill slit, here becomes narrow and curves downward around anterior edge of gill slit and
