Somewhat eel-shaped ; body and head compressed ; caudal section taper- 
ing; vertical fins continuous around the end of the tail. Length of head 
five and one half, and depth of body eight and one fourth times in the total 
length. Distance from snout to vent contained two and one third times in 
distance from vent to end of tail. Head compressed, nearly straight from 
nape to end of snout, convex transversely. Snout long, nearly three times 
as long as the eye, broad at the nostrils, broader than deep, blunt. Chin 
somewhat steep. Mouth wide, oblique; maxillary subtending the anterior 
third of the orbit, lower jaws longer, ending in a blunt angle below hinder 
part of orbit. Teeth small; in villiform bands on the jaws; in a crescent 
shaped band on the vomer; in a short group on each palatine. Eye small, 
hardly one sixth as long as the head, length rather more than width of 
interorbital space. No cephalic spines. Gills four, a slit behind the fourth ; 
gill rakers 1+ 13, short, stout; lamella very short, those on the upper 
portion of the arch being rudimentary. The upper section of the first gill- 
arch is very short, and bears but a single raker. Branchial apertufes wide ; 
membranes not united to one another, free from the isthmus. Vertical 
fins moderately deep, longest ray about as long as the snout; caudal indis- 
tinct; dorsal origin slightly backward from the axil of the pectoral; anal 
origin distant from the snout less than twice the length of the head.  Pec- 
torals small, not far from half as long as the head, narrow, pointed. No 
ventrals. Caudal indistinct, apparently of ten rays. Skin naked. Lateral 
line nearly or quite complete. Pyloric appendages two, short and thick.
