 Nile and Zambesi. By E. Kirkpatkick, F.Z.S.

(Plates XV.-XYII.*) 



Dr. W. A. Cunnington's collection of Freshwater Sponges 

 includes eleven specimens, nine from Lake Tanganyika, one from 

 the Victoria Nyanza, and one from Lake ISTyasa. 



The Tanganyika specimens, which are all in the form of thin 

 incrustations on stones and shells, represent three species, viz. 

 Spongilla moorei Evans, Spongilla tanganyihm Evans, and a new 

 species, which I have placed under Spongilla, and have named 

 after Dr. Ounnington — Spongilla cunningtoni, sp. n. 



The specimen from Victoria Nyanza belongs to Spotigilla carteri 

 Bowerbank, and that from Nyasa to Sp07igilla biseriata Weltner. 

 Most of the specimens wei'e obtained from quite shallow water, 

 "but some were dredged from 10 and 20 fathoms. 



I would here take the opportunity of desciibing three other 

 Freshwater Sponges from Africa, viz. a specimen from above the 

 Victoria Falls, Zambesi, collected and pi'esented to the British 

 Museum by Mr. C. F. Rousselet, and belonging to a new species 

 of Spongilla ; a second one from the same locality, representing a 

 new species provisionally placed under Spongilla, presented by 

 Prof. A. Dendy ; and, lastly, a new variety of Ephydatia 2:)lumosa 

 Carter from the White Nile, presented by Mrs. H. Broun. Six 

 species are now known from the Tanganyika area, four from the 

 lake itself, viz. Spongilla moorei Evans, S. langanyikce Evans, 

 aS'. citnningtoni, sp. n., and Fotamolepis weltneri Moore ; and two
