A small collection of fishes made by the Rev. R. H. Nassau, at 

 Great Batanga, and sent to Princeton University, has been studied 

 in this comiection. The collection is now in the museum of Princeton 

 University, and to the officers of the same I am indebted for the 

 opportunity of its examination. A list of the fishes was recently 

 given over my name.^ The first account of the Kamermi fishes is 

 Peters list of the Bucholz collection,^ though he describes the inter- 

 esting Pantodon about the same time.^ Since then the only accounts 

 are by Ehrenbaum * and Pietschmann,^ who note but few species.
