East Africa. 



Tbe following un figured species are said to belong here: 



* Unio mandinyuorum ROCHEBRUNE, Bull. Soc. Phil , 7th ser., VI, 1882, p. 34. 

 Bakoy, High Senegal. 



* Unio zeyheri, MENKE, Zeits. fiir Mai., VI, 1848. p. 28. 

 South Africa. 



teretinsculua Philippi, but a larger elongate solid rhomboid form, which is 

 certainly distinct. I therefore name it in honor of Jickeli. 



2 So in the first published description, probably a typographical error. I am not 

 certain as to the relationships of the species, but presume that it belongs here.
