9. Eleotris amblyopsis Cope. 



Surinam; Atlantic and Gnlf coast of the United States. 



We have examined fifteen specimens, 2J inches or less in 

 length, all from Stirinam, The scales in a median series 

 vary in these specimens from 40 to 44 ; in a transverse series 

 between second dorsal and anal, from 12 to 14. These are 

 the only characters which separate this species from E. 

 pisonis (Gmelin). 



The American species of Eleotris may be distinguished as 

 follows : 



a. Teeth sub-equal, those of the inner or ou!er series enlarged. 

 b. Cheek entirely scaled, 

 c. Teeth of the inner series of both jaws enlarged. 

 d. Scales in a median series 40 to 44; in a cross series 12 to 14.
