nuclus, described a scaleless sole from Bahia, Brazil, making it the 

 type of a new genus. 



The Tisbury Great Pond specimen of G. nudus is somewhat larger 

 and more circular jn outline than the Florida specimen of G. fasciatus, 

 darker in color, and has a straighter lateral line. It also appears to 

 have a longer head, somewhat smaller eye, and longer snout, but 

 otherwise, except in the absence of pectoral, agrees with it very 

 closely as it does with the description of G. fasciatus of Gunthe'r.
