" Another specimen of this shell from Darjiling confirms an 

 additional character for this species, tending still further to show 

 its relation to the more westerly Himalayan species C. strangulatus, 

 which was alluded to in my former remarks. The following 

 character should be added :■ — Callo suturali retrovcrso, pone con- 

 strictionem posito (ut in C. siran(/ulato)."

" I find in the collection four specimens of a small variety of this 

 shell, bleached, but otherwise agreeing with the specimen which I 

 noticed in the ' Annals ' for Oct. 1852, when recording the 

 additional character for the genus afforded by the presence of the 

 sutural tube. I can find no other feature to distinguish it from 

 the type than the more flatly expanded and distinctly doubled 

 peristome, in addition to the smaller size. As yet only a single 

 specimen of the larger type is known ; it is in a fresh state, but 

 slightly mutilated, and the colour is ])aler than in my specimen of 

 the smaller type. The latter is deficient in the distant ribs, but 

 they are plainly visible on more than one of Mr. Blanford's 

 weathered examples. A fuller comparison of a series of fresh 

 specimens of the two forms will be required to decide on their 

 claim to separation." 



This, I tiiink, can now be done, for among the Alyccei in the col- 

 lection of the Indian Museum, Calcutta, so kindly sent me for study 

 by Dr. IST. Annandale, is a tube labelled by G. Nevill : " Alycams 

 constriclus var. minor, Darjiling." It is referred to at foot of 

 p. 29-1 of the Hand-list he left to me, No. 54, as var. minor, Benson, 

 Ann. Mag. 1859, and received from Colonel Mainwaring. I cannot 

 concur with Nevill's determination, after comparing these speci- 

 mens, some 16, with Blanford's type shells, five in number, which 

 vary in size (I have figured the largest), and all are very much 

 bleached and worn, whereas those collected by Mainwaring are 

 very fresh with the sculpture well shown. Mr. Benson's original 

 descriptions were drawn up from this scanty inferior material, and 

 there is no reason why a variety should be constituted.
