Batrachus guavina Bloch & Schneider, Syst. Ichth., 44, 1801 (based 

 on Guavina of Parra). 



Habitat. — Rio Grande to Martinique, in fresh waters. 



This species is generally common in the streams of the West 

 Indies and Eastern Mexico. We follow later writers in changing 

 the incorrectly spelled dormitor of Lacepede to dormitator. 

 According to Poey, the type of Parra 's Guavina, still preserved 

 in the Museum at Madrid, has teeth on the vomer, and is therefore 

 a Gobiomorus, not a Guavina. The many specimens examined 

 by us are from Havana.

Eleotris longiceps Giinther, Proc. Zool. Soc. Lond., 1864, 151 ; Giinther, 

 Fish. Central America, 1869, 440 (Nicaragua). 



Habitat. — Lake Nicaragua. 



This species is known to us only from Dr. Giinther's description.
