XVII. — List of Land- and Freshwater- Shells collected by Dr. 

 Emin Pasha in Central Africa, with Descriptions of neio 

 Species. By Edgar A. Smith. 



[Plates V. & VI.] 



On the journey from the Albert Nyanza to Zanzibar in com- 

 pany with Mr. Stanley during the latter part of last year, 

 Dr. Emin Pasha found time to make collections of various 

 branches of natural history ; and he has been good enough to 

 send to the British Museum the shells he then obtained. 

 Being from such remote and little-worked localities, it is not 

 surprising that several of them are new to the National Col- 

 lection, and a few new to science. The following is a com- 

 plete list of the species with the exact localities which 

 accompany them. Many of these places do not appear in 

 maps which I have consulted, and consequently I am unable 

 to point out their exact position. I therefore have merely 

 copied the names as written by Dr. Emin himself. 



The majority of the new species hereafter described wei'e 

 collected by the llev. J. L. Last during his residence at 

 Mamboia about six years ago, and a few were obtained by 

 the late Bishop Ilannington in 1883. All the species are in 

 the British Museum.
