316 LAND AND FRESHWATER 



I examined another specimen to see that I had not missed anything. 

 I was glad to find fig. 6, made some years ago, was correct. The 

 complicated accessory organs of the African form, and also of that 

 described from the Caspian by Simroth, are represented in the 

 Afghan species by only one very elongate rod, as 1 may teim it, 

 for it is not a hollow sac, but of hard, close, granular texture, 

 within nothing lilie a dart to be seen, and apparently a secretory- 

 organ only. 



The anatomical differences the Afghan species exhibit are, I 

 consider, quite worthy of subgeneric se])aration, and 1 therefore 

 retain the original name Candahnria, which I gave it prematuTcly 

 and before I knew enough of its relationship. I do not consider 

 this species from tlie Kojhak Pass as likely to be the same as 

 Farmacell'i rutellum of Hutton, only 12 mm. in length. Its colour, 

 noted by Hutton, is very distinctive " bright gamboge-yellow," and 

 I think my old assistant Ogle would have mentioned the character 

 in his letter, above quoted, had they been so conspicuously coloured. 

 Khojak sj)ecimens in spirit are grey, in life ])ossibly green. Species 

 of this genus may very possiUy occur at Quetta and adjacent 

 valleys ; I hope I may be able to interest someone quartered 

 there to look for them. This I have done during the past year, 

 1913. 



Colonel F. Webb-AVare, C.I.E.. political agent at Chagai, has 

 very kindly made enipiiry, and, through him, the i)olitical agent at 

 Thol, but with negative results. He has heard (April 1914) of 

 large yellow slugs t)0 miles from Nushki. Enquiry made of the 

 lialuchistan Natural History Society was equally barren. More 

 successful in search of land-shells has been my brother-in-Liw, 

 Captain D. G. Eobinson, who was at the Staff College, Quetta. On 

 Zerghun Peak at 9500 ft. he has sent me three species — a most 

 interesting small Zonitoid (perhaps a new genus) and two species 

 of Pupa. This instalment is very promising. Baluchistan is a 

 country of sand, barren rocks, and arid plains, quite unworked, but 

 I feel sure numerous species are to be found there. 



Captain Hutton, in the same paper in which he describes Par- 

 macella rutellum from Kandahar, described Vitrina bcacata. I 

 have a copy of this paper given me in ] 862 by him, on which he 

 wrote " proves to be the young of P. rutdhnn." As the early 

 stage of this mollusc is of considerable interest, I quote Hutton's 

 description : — 



" 2. YiTETNA BACCATA. 



"This very minute species was found under stones along the 

 bank of a dry nullah or river-bed, at a place called Melmandeh, 

 between the Kojuek Pass and Kandahar. It appeared to be very 

 scarce, as after a lengthened search onlj- three specimens were 

 found, and of these unfortunately the animals died before an 

 opportunity occurred for examining them. Shell small, thin, 

 fragile, diaphanous and pale ; whorls apparently only one, or at all 

 events the body-whorl may be said to constitute the whole shell ; 

 aperture nearly circular, lips scarcely interrupted, slightly thickened
