projection. It is possible that punctulatus may be a distinct 
species ; but there is not yet sufficient evidence for classing 
it as such. 
Chlamydephorus Gibbonsi , W. G. Binn. 
Length 47 millim., orifice 7\ millim. from posterior extre- 
mity. Sole not differentiated into parts, smoothish, 5 millim. 
broad. Tentacles (eye-peduncles) pale bluish grey. Colour 
pale yellowish, becoming dark grey on back, with more or 
less of a pale dorsal line of ground-colour. Reticulations 
polygonal, w T ith the interstices minutely subdivided. Sole 
slightly transversely grooved. Mantle none. 
Described from a specimen in the British Museum from 
Cape Colony ( F . P. M. Weale). 
Apera , the name proposed by Heynemann for this genus, 
will probably have to be used. Chlamydopliorus (Hark) was 
proposed for a genus of Mammalia as early as 1825.

XLYI . — A List of the Species of Achatina from South Africa , 
with the Description of a new Species . By Edgar A. 
Smith. 
In the endeavour to identify the new form hereafter described 
it was necessary to find out what species were already known 
from the region where it was discovered. In doing this it 
appeared that it would be useful to get together a list of all 
the forms known to occur in the southern portion of the 
African continent. This I have done, arbitrarily limiting the 
area on the north at the 20th parallel. 
Already as many as eighteen species have been described, 
and doubtless this number eventually will be increased con- 
siderably when this region, and especially the mountainous 
parts, has been more completely explored. 
A number of the Achatince from various parts of Africa 
seem to differ only very slightly from allied forms, and it 
may fairly be anticipated that the separation of species will 
become more and more difficult through the discovery of 
intermediate forms in parts hitherto unexplored.
