Head 4^; depth 3^ to 4; D. 14 to 16; A. 12; scales 18-55. Body 

 rather elongate, not much compressed, back not much elevated; inter- 

 orbital space slightly convex, its width 2 in head; snout 3^ in head; 

 diameter of eye 3 ; origin of dorsal in advance of anal midway between 

 tip of caudal and tip of snout ; distance from origin of dorsal to base of 

 caudal if in its distance to tip of snout; fins rather large; pectorals 

 i % in head ; ventrals 2 ; caudal fins slightly emarginate ; caudal pe- 

 duncle slender, its least depth 2 in head. 



Color brownish above, the posterior portion of each scale darker, 

 giving a finely speckled appearance; a narrow blackish lateral band 

 extending from above the opercle nearly to base of caudal, the pos- 

 terior portion of the band more distinctly defined posteriorly ; beneath 

 this band the body is mostly straw color with a variable number of 

 small brown specks; dorsal dusky, with a submarginal line of black, 

 the margin plain; base of caudal fin dotted with several transverse 

 rows of dark dots and usually a clearly defined narrow black sub- 

 marginal band, the tips plain; anal with a central short black bar; 

 ventrals usually plain, sometimes with black tips. I take pleasure 

 in 'naming this fish for Mr. E. A. White, of the city of Mexico, in recog- 

 nition of many favors received through his courtesy.
