XVII. — List of Land- and Freshwater- Shells collected by Dr. 
Emin Pasha in Central Africa , with Descriptions of new 
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 1 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 were 
collected by the Rev. J. L. Last during his residence at 
Mamboia about six years ago, and a few were obtained by 
the late Bishop Hannington in 1883. All the species are in 
the British Museum.
