NOTE ON SOME GYMNOTID FISHES. 



The following species of this family (Gymno- 

 tidee) were noticed in the collection of the Academy 

 of Natural Sciences of Philadelphia. As they have 

 not been studied for many years, and several are new 

 records, they are offered as a slight contribution to 

 science.
