MOLLtJSCA OF INDIA. 17 



by Glide in Fauna B. India, vol. ii. p. 414). In a paper by tliem in 

 the Journal of the Asiatic Society of Bengal (vol. xli. 1872, p. :-i41) 

 thoy say: "somewhat larger than the Wkhimtype shell." This 

 record is of little value, when one considers how cursorily some 

 shells, particularly of Glessida, have been looked at and how little 

 time^ is often bestowed upon them. Xovill in his Hand-list, 

 p. 169, only gives the Darjiling locality. Theobald, it would appear, 

 never gave specimens to the Calcutta Museum, and it is impossible 

 to say where these shells of his went to. 



In W. T. Blanford's collection is a single typical specimen 

 (No. 880.06.1.1), and on a label in Hanley's handwriting a noto 

 "Identical with the large one figured in the Conch. Indica" 

 (Plate XVIIl. fig. 4). Two specimens were in the Henry Blanlord 

 collection which may be considered also typical, as the two brothers 

 were constantly exchanging specimens. 



I find Glessula hastula, Bs., does not extend to the Garo and 

 Khasi Hill ranges, its place being taken by a shell at first sight very 

 similar to it, but which on close examination is found to difier 

 sufficiently to describe, making it all the more improbable that 

 G. haslula extends to Arakan. G. hastida of Darjiling is more 

 attenuate with more costulate sculpture than in the Khasi form. 

 . Apex enlarged of (880.06.1.1 B.M.) Plate CLXIII. figs, i), Q,,, 

 Darjiling, and of (557 B.M.) fig. 10, Itichila. 



It may be noted that the apex of the last differs very much from 

 that of a typical hastida, a good character and sufficient to create 

 a. species which I name after Mr. W. Eobert, late of the Indian 

 Survey, who made for nie such a splendid collection when he was 

 working in Sikhim. There are only two specimens and one 

 other from liis.som Peak (Xo. 2483 B.M.). It is very possible 

 other examples will be found among my sjiirit-specimens.
