 stripe along upper margin of opercle, through lower margin

32 Gobius stigmaticus Poey. 



West Indian fauna; Southern United States to Eio Janeiro. 

 The specimens in the Museum are from Cuba and Rio Janeiro. 



We have compared the specimens collected by Prof. 

 Agassiz with the type of Poey. The Rio Janeiro specimens 

 are darker than the type; the bars on the cheek are con- 

 spicuous, edged with white; the shoulder spot is larger tlian 

 the eye. The third dorsal spine sometimes is very elongate, 

 reaching the fifth or sixth dorsal ray ; the last dorsal ray oc- 

 casionally extends to the base of the caudal. Posterior 

 canines of lower jaw conspicuous, two on each side in some 

 examples. The canines are also present in the typical 

 specimen.
