MELANIIDE. 209 
Show no trace of longitudinal ribbing. Long, 10, diam. 
52 mil. 
subvar. bicolorata. 
12 W. of Shiraz; coll, W. T. Blanford, Esq. [173, 8]. 
subvar. acuticarinata. 
2 Persia; coll. W. T. Blanford, Esq. (131, 74]. 
M. Bourguignat’s pl. XV, fig. 25, Malac. Alger, gives a fair 
idea of this interesting form, which, however, is smaller, not 
decollate, of paler colour, obsoletely banded, with the keel even 
more developed. 
subvar. decollata. 
Philippi, 1. ¢., fig. 7 3 ? M. fasciolata, Parreyss. 
20 Persia; coll. W. T. Blanford, Esq. [19, 9]. 
A very distinct, thin, eroded, slightly decollate variety, whorls 
usually less convex than in the quoted figure; under the lens 
minutely, flexuously striate; two or three show distinct, longi- 
tudinal, distant ribbing as well, much as in Rossm., fig. 1883 
[L. tingitana, Morl.]. It is perhaps as closely allied to Issell’s 
M. doriw,—seems, indeed, to be a connecting link, 
var. dori. 
Melanopsis Doriz, Issel, Moll. Persia, 1865, long. 24, diam.8 mil.— Kerman, 
30 Kerman [S. Persia]; coll. W. T. Blanford, Esq. 
From the same spot as Prof. Issel’s type, with which they 
agree exactly. 
subvar. carinifera. 
10 Kerman; coll. W. T. Blanford, Esq. 
A very interesting form, with a raised keel running along 
the suture.
