had gone to Calcutta. Dr. Annandale very kindly sent these to 

 me (October 1916) and I have compared them with specimens of 

 G. hotellus in the Henry Blanford collection from the Nilgiris» 

 with the result that I cannot confirm Mr. Preston's determination. 

 This Abor Glessula (oakesi) is decidedly smaller than G. botellus, 

 and not so tumid, the whorls are closer wound, the outer lip is 

 much more thickened than in botellus, the larger shell. I have 

 compared the embryonic whorls and made enlarged drawings of 

 botellus, of Mr. Preston's specimen, and of the type specimen of 

 oakesi, the difference between the first and the two last is very 

 marked, it is unmistakable. 



Some explanation from me is necessary here. The shells

treated of in Mr. Preston's contribution form a small part of the 

 collection made by Mr. Kemp, sent to me by Dr. Annandale with 

 instructions (January, 19 14) to hand to Mr. Preston those I did not 

 propose to work on myself, the museum numbers were only 

 noted of those so handed over. It was also unfortunate as men- 

 tioned before that in one box sent home shelb in glass tubes col- 

 lected in Lower Burma were packed with others from the Abor 

 Hills, two or three tubes were found broken and the contents at 

 the bottom of the box, these were taken over by Mr. Preston. This 

 accounts for errors in locality, for which Mr. Preston cannot be 

 blamed. Collections from different areas should never be put up 

 together and sent through the post.
