Postscript to the Monograph of Himalayan and Barmese 



Clausill/e, — by Dr. F. Stoliczka. 



(Received 31st July, 1872.) 



(See plate IX.) 



In looking through the proof-sheets of Mr. Blanford's paper, while they 

 passed through the press, and comparing his descriptions with the specimens 

 of Indian and Barmese Qlausilice in my collection, I find that a few additions 

 can be made to the Monograph. The new species are figured on the same 

 plate, IX. I would have gladly handed over the additional materials to 

 Mr. Blanford, hut as he is now engaged on an expedition in Persia, and may 

 not for some time return to Calcutta, I do not think it advisable to defer 

 on that account the publication of these notes. 



I have only to observe that I had an opportunity of comparing some of 

 Mr. Theobald's original specimens, and have thus been enabled to add some 

 information regarding the synonymy of one or two doubtful species. 



1. Cli. CYLLNDRICA. (Ad p. 199.) 



I have specimens of this species from near Tezpur (Asam), and Dr. 

 Waagen very recently brought one from near Marri ; the geographical dis- 

 tribution of the species may, therefore, be said to extend over the whole of 

 the southern slopes of the Himalayas, though its head-quarter appears to be 

 about Nyni-tal, or near the centre of the range. 



3. Cl/. bacillum. (Ad p. 200.) 



This species varies considerably both in the form and length of the shell. 

 The specimen figured may be taken as the type, but others longer and slenderer 

 are quite as common, they very closely resemble Theobalcli in form, differing 

 from it by then smooth shining surface. One of the most slender speci- 

 mens measures : total length 15, thickness 3 mm. ; it has 10^- whorls and is 

 much attenuated towards the apex. 



The representation in the ' Conch. Indica' must evidently be taken as 

 that of true bacillum, of which, the authors of that work say, two specimens 

 were known at that time : one in Benson's and the other in Theobald's col- 

 lection. These are the two specimens to which Theobald (Journ. A. S. B., 

 1858, p. 321) refers under the name of ignota, as a provisional name, while 

 the single specimen which he quotes 1. c. as ' O. Bacillun, B.' is a somewhat 

 worn Cl. Asaluensis, and hence Theobald's reference that the species is of 

 the type of C. insignis. I have carefully examined with Mr. Theobald his 

 type specimens, and the question as regard the synonymy may be considered 

 as settled ; the species must stand as recorded by Blanford.
