the eye and somewhat narrower than the last slit. Length 
of head and trunk 1°25 in that of the tail. First dorsal fin 
originating above the posterior half of the base of the 
ventral, its distance from the tip of the snout 2°25 in the 
total length; anterior and outer borders of fin feebly con- 
vex, the intervening angle rounded as also is the hinder 
angle; hinder border feebly emarginate, its length 1°50 
times the diameter of the eye and 2°10 in the basal length, 
which is less than the vertical height of the fin; second 
dorsal slightly longer but not so high as the first, its dis- 
tance from the origin of which is 2°65 in that from the tip 
of the tail. Distance between origin of anal and second 
dorsal equal to the interval between the dorsals and 3°50 
in its distance from the ventrals; its height is 1°75 in its 
base, which is only separated from the caudal by a notch. 
Depth of lower caudal lobe 4°60 in its length, which is 3°80 
in the total length; extremity of fin rounded and mesially 
notched, the tip of the vertebral column not reaching the 
margin. Pectoral fin obovate, originating midway between 
the ventral fin and the tip of the snout or somewhat nearer 
to the former, its base 1°60 in its greatest width and 2°25 
in its length, which is 1°40 of that of the head. Origin of 
ventral fin considerably nearer to first dorsal than to 
pectoral. Back with two to five series of tubercles between 
the occiput and the first dorsal. Above dark plumbeous, 
with nine narrow lighter cross bands, the trunk and tail 
with more or less numerous and distinct round whitish
