eo on A Can. 
RECEIVING some years ago a quantity of shells from Port 
Elizabeth, some of which I could not identify with any that 
had been described, I,contributed a paper to the ‘ Journal of 
Couchology,’ January 1886, consisting of a list of those I had 
identified, and descriptions of those which appeared to be 
new. This led to the publication of two subsequent papers 
in the same Journal, through my communications to the 
Conchological Society in 1889, considerably increasing the 
list. Since then, various friends in South Africa have 
discovered many additional species, some of which are well- 
known inhabitants of other coasts, but not previously recorded 
as South African. 
The purpose of the present work is to give in a small 
compass a list, as complete as possible, of aJl the known 
Marine Shells of South Africa, with references to figures in 
well-known works, descriptions of new species, and figures 
not only of these, but of some that have been described 
from time to time by other authors without figures. 
The total number of species enumerated is 740. Of 
these, 67 are also found in European seas, 340 are known 
to inhabit other coasts, and the remaining 323 are, as far as 
is known, confined to South Africa. 
The labour of sorting and identifying so many species 
(many of them very minute) has been considerable, and the
