1, 2. Lake Mareotis. — Schoeller. 



3. Mbusini, German E. Africa. — Stuhlmann. (Type.) 



4, 6, 7. Gharb-el-Aish. — Loat. 



5. Bujiju, Uganda. — Dawe. 



This species was first discovered at Mbusini, in German East Africa. One of 

 the specimens, received from Prof. Pfeffer, is preserved in the British Museum. 

 Mr. Loat collected numerous specimens in the White Nile and the Bahr-el-Gebel, 

 and Mr. H. Schoeller found the species, which he named Chromis multicolor, in 

 Lake Mareotis. The fish is also found to the west of Lake Victoria *. 



* Pellegrin, Mem. Soc. Zool. France, xvi. 1904, p. 336, is certainly mistaken in regarding this fish as the 

 young of T'dapla JcirJcii, Gthr., which inhabits Lake INyassa and the Shire Eiver.
