Norman '" has revised the species of Poecilopsetta. Only two species 

 have been known from the New World, P. beanii (Goode) and P. 

 inermis (Breder). P. albomarginata, which has been compared di- 

 rectly with the type and other material of P. beanii, differs from this 

 species in the deeper body, the larger scales, the coloration, and other 

 respects. It appears to dififer strikingly from P. inermis " in the milk- 

 white fin edging, the absence of any trace of color pattern on the blind 

 side, and especially in the strongly ctenoid scales of the eyed side.
