Twenty-seven species, one of which is recognized as new : 
two (Limicolaria) are known from the coast of Guinea ; seven 
are South African types; four {Limicolaria niloticaj Achatina 
spekei, Cyclostoma calcareim, and Ampullaria speciosa) appear to 
belong to the equatorial parts of East Africa; one {Navicella) 
found at Johanna Island, Zanzibar, is a well-known species from 
Madagascar ; the remainder are known from the Nile. It is 
much to be regretted that the exact localities of several of them 
could not be given, in consequence of which it remains doubtful 
whether some well-known species from the Nile are found only in 
tributaries of that river or also more southwards, and whether 
some South African species inhabit also the uppermost part of 
the Nile. Lanistes boltenianus {Ampullaria carinata^ Olivier, sp.), 
Paludina unicolor, and P. bulimoides, the three most common 
and most characteristic freshwater Gasteropods of the Nile, 
are stated to inhabit the Lake Victoria N'yanza ; Etheria caiL 
liaudi is said to be confined to the Upper Nile.

These reports on the latest collections made by Messrs. Wright, 
Arango, and Gundlach in Cuba contain not only descriptions of 
new species, especially of numerous Macroceramus and Cylin- 
drella, but also new localities, and descriptions of the external 
soft parts of species previously known and belonging to the 
families Helicidce, Cyclostomida:, and Helicinidce.
