as deep as long, with about 10 rays ; caudal fin slightly forked. 
Scales large and uniform, finely serrated on the hinder border, not 
deepened or thickened along the course of the lateral line. 
So far as can be determined from the skeleton, this genus 
appears to differ from the surviving Scopeius only in the compara- 
tively small size and remote situation of the anal fin, and in the 
sei rated character of the scales.

the type species, attaining a length of about 0 - 2, but usually 
smaller. Length of head with opercular apparatus considerably 
exceeding the maximum depth of the trunk, and equalling at least 
half the length of the trunk from the pectoral arch to the base of 
tfie caudal fin. Vertebra; about 32 in number. Pelvic fins arising 
°Pposite the origin of the dorsal, much nearer to the pectorals than 
to lfi e anal ; dorsal fin about as deep as the trunk at its origin, 
comprising 12 or 13 rays, of which the two foremost are short and 
8 P>nous, the third the longest and articulated though not divided 
distally, and the others both articulated and divided distally ; anal 
fin resembling the dorsal, but comparatively small and remote, w ith 
on ly 10 rays. Serrations of scales deep and conspicuous.
