From the latter locality I have just received 
this shell under the erroneous name of Sogdia- 
nus, var. major. It is quite distinct in color, 
texture, peristome, number of whorls, broadly 
reflected peristome. I have a variety, major, 
and a variety, gracilis, of this shell, and all 
preserve their charactcrs with great uniformity.

I have received from the neighborhood of 
Samarkhand some very fine shells I cannot re- 
frain from uniting with this species, still they 
differ in colour having a shining surface,nearly 
uniform somewhat bluish-gray colour faintly 
variegated on the upper whorls, with corneous 
apex and pale chestnut aperture becoming 
lighter towards the peristome. The above 
form should be named var. hepatica, Anc., 
long, 18%-20; diam. 8-8'%4; length of aper- 
ture, 6-61%4 mill.) Whorls, 7-7%. A very fine 
variety of the same form also occurred, being 
of a more oval shape and larger, (long, 24; 
diam. 10; length of aperture, 8; breadth of 
aperture, 5% mill.) It might be called var. 
procera on account of its large size. The 
colour is the same as in the preceding one. It 
has 7% whorls.—Samarkhand.
