Southern Nigeria. Several specimens v/ere obtained in 

 swamps between Agwarba and Awka by Mr. R. D. Gard'ner. 

 I have received others from the mouths of the Niger and Old 

 Calabar through Mr. J. Paul Arnold, for whom I had identi- 

 fied them as //. senegalensia, Stdr. I now think they repre- 

 sent a distinct species, characterized by longer ventral fins.
