ADDITIONAL List oF GEOGRAPHICAL ITEMS MENTIONED IN THIS PAPER 
The following directory contains only the geographical items which 
were not previously listed in the senior author’s ‘Review of the Land 
Mollusks of the Belgian Congo.’! It may be well to point out that the 
two lists contain all African localities mentioned in the two reports and 
not only those of the Belgian Congo; also that, while different spellings 
or names of the same locality have been listed in the directories, a uniform 
spelling of each of them has been strictly adhered to in the text. There is 
therefore no duplication of records on that account, except in a few 
dubious cases when this is expressly stated. In the Belgian Congo 
terrestrial and aquatic mollusks have been collected thus far in not 
more than 400 localities (including mountains, rivers, and lakes).
