inent above the vomer, bluntly rounded at the end. Mouth wide, with 
the maxillary subtending the anterior third of the orbit. Cleft to a vertical 
from the front margin of the eye. Teeth small, in villiform bands on jaws, 
vomer, and palatines. Eye large, one sixth of the head, more than the 
interorbital space, one and one half to one and three fourths times in the 
snout. Nostrils small, tubular, near the end of the snout. A low median 
longitudinal crest on the top of the back of the head. Opercle long, with 
a flexible point on the upper angle. Dorsal and anal confluent with the 
caudal fin. Origin of dorsal above the axil of the pectoral; longest rays 
as long as the snout; fin rising gradually both from crigin and from caudal. 
Anal similar to dorsal, originating below the seventeenth ray of the latter. 
Caudal not distinct from D. and A., forming a short point. No ventrals. 
Distance to vent from pectoral bases two thirds of the length of the head. 
Pectorals one and one third times as long as the head, peculiar in being 
narrow at the base and greatly elongated in the rays of the upper half or 
two thirds of the fin. These prolongations are very flexible, and in some 
features resemble nuptial growths on certain other vertebrates. The rays 
project beyond the membranes on the edges of the fins. On a smaller 
specimen, of nine and one half inches, the pectorals have the same shapes 
but are proportionally shorter, being only as long as the head. Bones of 
the head not particularly firm, with extensive chambers or cavities. Skin 
thick on body and fins, soft. Scales very small, absent from head, shoul- 
ders and fins. Lateral line invisible. 
Brownish, possibly tinted with red in life; dorsal and anal posteriorly 
and caudal blackish; pectorals whitish ; lower surface of head whitish. 
The specimen described and figured had an entire length of seventeen 
and one half inches.
