The scales are quite small, longer than deep, cycloid in 
structure, with diverging grooves upon their anterior section 
only. The lateral line is slightly arched above the pectorals, 
thence nearly straight along the middle of the flanks to the 
base of the caudal fin. A similar mucous line may be 
traced from the upper rim of the upper eye, along the back, 
giving off an anastomotic branch to the lateral line across 
the occipital region, and losing itself in the, dorsal fin, 
beyond the middle of the length. 
The ground color is grayish or plumbeous, densely sprin- 
kled all over with black dots and whitish spots; the fins 
being olivaceous, similarly dotted with black, but exhibit- 
ing fewer white ion.
