1. Sternarchus leptorhynchus Ellis. 

 Of this species, hitherto known only from the Essequibo basin of British 

 Guiana, one specimen 130 mm. (5593a C. M.)was taken by Henn in a small 

 creek near the mouth of the Calima, and one specimen 209 mm. (13374 I. U. M.) 

 was taken by Eigenmann at Cordova in the Dagua river. Both of these locali- 

 ties are on the Pacific slope of Colombia.
