Scytalina, gen. nov. 
Family Congrogadide, allied to Congrogadus Giinther. 
Body anguilliform, cylindrical anteriorly, compressed behind, covered 
with very small, imbedded cycloid scales. No lateral line. Head broad, 
with tumid cheeks, broader than body, resembling a serpent’s head. 
Lower jaw slightly projecting. Each jaw with two strong canines in 
front, besides which is about one series of small, close-set conical teeth 
in the lower jaw and a broad patch in the upper. <A single series of 
small teeth on vomer and palatines. Branchiostegals six. Gill-open- 
ings very wide, the membranes broadly connected below and free from 
theisthmus. Pseudobranchie small, present. A slit behind fourth gill. 
Tongue largely free anteriorly. Intestines short, without pyloric ceca. 
Pectoral fins very small. No ventral fins. Dorsal fin very low, without 
spines, beginning near the middle of the body. Anal similar, and begin- 
ning nearly opposite it. Tail rounded behind. Caudal fin well devel- 
oped, joined to dorsal and anal. Vent near the middle of the body. No 
anal papilla. 
Etymology: diminutive of Scytale, a genus of serpents, in allusion to 
the form of the head and neck and the fang-like canines. 
The relations of this genus seem to be with Congrogadus Giinther, from
