Roeboides dayi (Steindachner) ?

AHF 2641, from near a dock in the river at Barran- 



quilla, Colombia. 



Remarks: This material was determined with the aid of Schultz 



(1944). One specimen appeared to fit well the description given by 



Schultz for R. d. dayi (Steindachner) and the other was intermediate 



between that subspecies and R. d. dientonito Schultz. Inasmuch as both 



of our specimens were taken at the same time from the same locality, the 



validity of the latter form is questioned.
