' I have retained the species of this family as recog- 

 nized by Regan. Evermann & Kendall (Proc. Biol. 

 Sec, Wash., xviii, p. 91, 1905) think that many are 

 probably synonyms. 



I am not certain of the position of most of the 

 localities of this genus, whether on the Amazonian or 

 Pacific slope. I have taken it for granted that they are 

 from the Atlantic slope unless specifically stated that 

 Ihcv are from the Pacific side.
