large, slender and pointed, widely spaced and irregular in size. 
Vertebrae about 40 in number, half being caudal; the centra rather 
longer than deep, and the arches in the caudal region comparatively 
short. J^o fin-rays excessively elongated, but the dorsal and anal 
fins much elevated in front and low behind. Pectoral fins com¬ 
paratively large, close to the ventral border, the rays not quite 
reaching the pelvic fins, which are small; dorsal fin with about 
10 rays, arising at or near the middle point between the occiput 
and the caudal fin ; anal fin relatively large, arising opposite the 
hinder end of the dorsal and extending nearly to the caudal fin, 
with at least 20 rays; caudal fin considerably forked.

Type. Nearly complete fish ; British Museum. 
The type species, attaining a length of about 0*18. Form and 
proportions uncertain owing to distortion of specimens, but the 
length of the head with opercular apparatus apparently nearly 
twice as great as the maximum depth of the trunk and about one 
third the length of the vertebral column. Teeth very slender, some 
recurved. Pelvic fins arising nearer to the anal than to the pectoral 
pair; dorsal fin arising at the middle point between the occiput 
and the caudal fin, the length of its base-line about half that of 
its longest ray which approximately equals the depth of the 
trunk at its insertion ; anal fin arising nearly midway between 
the pectorals and the caudal, its front portion symmetrical with the 
dorsal, its hinder portion very low and fringe-like.
