8. Gabun, French Kongo. 



The first enumeration of Gabun fishes Avas made by Dumeril, in 

 his paper already referred to under the Cape de Verde Islands. 

 Giinther describes a number of new species from the Gabun. ^ 

 Sauvage first notes the fishes of the Ogooue,^ later elaborated in 

 his "Etude sur la Faune Ichthyologique de FOgooue,"' and, finally, 

 his ''FranciviUe, Haute Ogooue."* Boulenger describes a new 

 siluroid^ and a new cichlid.« More recently numerous papers by 

 Pellegrin have appeared.^ The material on which the present 

 account is based is the old collection made by P. B. DuChaiUu received 

 in 1854, and a small lot obtained a few years ago by the late Rev. 

 R. H. Nassau. The Du Chaillu collection is contained in the Academy 

 of Natural Sciences of Philadelphia, while those received from Nassau 

 are in the University of Pennsylvania. The former are indicated by 

 D. and the latter by N.
