close to the ventral border; pelvic fins smaller, opposed to the 
dorsal fin, which is situated within the anterior half of the back 
aud exhibits one anterior ray excessively elongated and closely 
articulated ; anal fin very small and remote ; caudal fin stout but 
deeply forked. Scales large, smooth, and uniform, moderately thick, 
not serrated at the hinder border; lateral line conspicuous.

The type species, attaining a length of about 0’12. Length of 
head with opercular apparatus apparently about equalling the 
maximum depth of the trunk, and half its length from the pectoral 
arch to the base of the caudal fin [but all known specimens con¬ 
siderably distorted]. Pectoral fins with about 10 rays, of which 
one or more of the foremost are very stout and closely articulated 
and not divided distally; pelvic fins with 7 or 8 stout divided rays, 
arising opposite the anterior half of the dorsal fin, much nearer to 
the pectoral pair than to the anal; dorsal fin comprising one short 
spinous ray in front, next a longer ray, closely articulated though 
not divided distally, next a simple, articulated ray excessively 
elongated to an extent equalling about two thirds the length of the 
back behind its insertion, finally 9 rays of moderate length, 
shortening backwards, all both articulated and divided distally ; the 
space between the dorsal fin and the occiput slightly exceeding 
the length of its base-line, the space between the dorsal and caudal 
fins equalling from two to three times the same measurement; anal 
fin with about 8 rays, separated from the caudal by a space approx¬ 
imately equal to the length of its base-line.
