LT. — Notes on African Non-marine Mollusca, with 

 Descriptions of many new Species. By M. Connolly. 



[Plate XIV.] 



In the years just preA'ious to 1914 an enormous amount of 

 material of the highest conchological importance was sent 

 home from Tropical Africa by Messrs. A. Hlayney Percival, 

 Robin Kemp, and C. W. AVoodhouse. Some of the results 

 of their labours were published by H. 13. Preston in a series 

 of short papers on a wide range of genera, culminating in 

 two longer articles specializing the Streptaxidse and Zouitidac 

 of that part of the Continent. 



It is common knowledge that much further work was in 

 contemplation by the same author ou the Stenogyridae and 

 other families; descriptions and even figures of many new 

 species had been prepared and were ready for press, when 

 sundry world-wide disturbances delayed publication, which 

 it has hitherto Ijeeu impossible to resume. 



It has now been my good fortune to acquire from J\fr. 

 Preston the whole collection of over 300 shells selected ])v 

 him as types of the unpublished species, and 1 propose to 

 deal with these and a few from other sources in the following 

 series of papers. 



As early puidication was expected, many paratypes were 

 distributed by Preston before the war and find place in
