/ 

 M. Bourguignat's pi. 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. decoUata. 



Philippi, I. c.,fig. 7 ; ? 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 

 \_M. tingitana, Mori.]. It is perhaps as closely allied to Issell's 

 M. dorice, — seems, indeed, to be a connecting link. 



var. dorise. 



Melauopsis Dorise, 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.
