Range. West coast of Lower California, and Clarion Island of 

 the Revillagigedo Archipelago. 



We have examined a specimen taken by Mr. R. C. McGregor at 

 Todos Santos Island, which differs from the description of the type 

 in the distinctly ctenoid scales, in the fin formula, the dorsal being 

 VI I, 12, the anal I, 9, and in the teeth of the lower jaw, which are 

 in a double series, the outer enlarged and spaced, followed by a series 

 of much smaller and more numerous inner teeth. The discrepancies 

 between this specimen and the type are undoubtedly errors due to the 

 small size, 12 mm., of the latter.
