Here described from several specimens from Haiti, St. Vincent, Dominica, and 
Pernambuco, measuring up to 160 mm. in total length. This series of examples 
includes some with the cheeks wholly or partially naked, corresponding to E. perniger, 
and others which closely approach E. abacurus, Jord. & Gilb., in the small number of 
scales in a longitudinal series. 
E. amblyopsis, Cope, is a closely allied species, but appears to have larger scales. 
* Eleotris brasiliensis, Sauv., 1880, is probably not distinct from E. guavina. 
+ This or a very similar species has been recorded from West-African rivers.
