 (With Plates X and XL) 



Previous to liis appointment to the Yarkand Mission, Dr. F. Stoliczka 

 had been working for some years at the animals of the Indian land Mol- 

 lusca, and had enriched this Journal with many valuable papers. Among 

 the numerous MSS. he left behind him in Calcutta, there were found, after his 

 death, some very excellent drawings that had been made under his superin- 

 tendance from the living animals ; they had been drawn on scattered 

 sheets of j^aper, and remarks on the colour and other characters of the soft 

 ]Darts had been made in pencil on the margins, which were fast becoming 

 illegible. I, therefore, with the concurrence of Dr. J. Anderson, pasted 

 these interesting drawings into a scrap-book* and copied into it, as well 

 as I was able to decipher them, the names, localities, and remarks noted. 



As it may be some years before many of these species are obtained 

 again by any naturalist with the means or talent to correctly draw them, 

 I have thought that lithographed copies published in this Journal would not 

 only be preserving, but in a measure carrying out the work of so good an 

 observer, and would be of use to those in India who are interested in the 

 land-shells of the country. There is an immense amount of work to be done 

 in this particular branch of Natural History. We know as yet very little 

 of the relationship of the many s])ecies, especially among the Zonitidce 

 (Semper) ; the anatomy of most of them has never been examined, and, until 

 this is done, or at least more careful descriptions and sketches of the out- 

 ward form of the animals are made, our attempts at a satisfactory classifica- 

 tion must fail. 



I have to each species figured given Stoliczka's remarks and identifica- 

 tions in full, and added a few notes extracted from my field-book wherever 

 I could do so, and I also distinguish a few identifications by Messrs. W. T. 

 Blanford and Geoffrey Nevill. 



The plates that will be given contain species of the family Zonitidas 

 variously assigned to the genera Ariophanta, IIemiplecta,-\ Ehysota, Xesta, 

 and Rotula ; and one plate has been required for the Helicidce of such very 

 different genera as Plectopylis, Fruticicola, &c ; those of the genus Macro- 

 chlamys, I have also copied, but as I am engaged on a paper treating of this 

 group more in detail, which I propose to send to the Zoological Society of 

 Loudon, the plate will I hope appear in the Journal of that Society.
