3I0LLUS0A or INDIA. 15 



" This species appears to have escaped the notice of all prsTious 

 collectors in iSikkim ; it was tound in association with its near ally 

 Q. tenuisplra, Bens., by Dr. Stoliczka during a recent visit. It is 

 easily distinguished from the latter species by its slenderness (the 

 diameter being \ of the length), and the comparative narrowness of 

 its whorls ; moreover, by the form of the columella, the lower part 

 of which is bent abruptly almost at right angles with the slope of 

 the inner lip : while in G. ienui^jiira, G. erosit, and other allied 

 forms, the curvature is at the iituuj:?t obtuse. Specimens, the shell 

 of which had been slightly wealhiTed, show fine spiral markings, 

 but these are not visible unless the shell has become somewhat 

 opaque. Tlie animal is dark leaden grey, somewhat paler at the 

 sides of tlie foot. 



" The following is a list of the species now known from Sikhim : — - 

 G. ttnuispira, Kens., G. erassula, Bens., G. hastula, iiens.. G. orobia, 

 Bens., Gr. erosa, nob., G. bacidma, nob." 



When going through Henry Blanford's collection, bequeathed to 

 the British Museum by his brother, I came on the type specimens 

 of the above species ; these I had not seeu for 46 years. At the 

 time I was stayiug with him in Calcutta, he placed them in my 

 hands to figure for a paper he was preparing for the Asiatic Society 

 of Bengal, vol. xl. pt. 2, 1871, p. 39. It is a very distinct species. 

 I have (luite a large series obtained since from different localities 

 in Sikhim and Western Bhutan. Beddome (Pro. Alalacol. Soc. 

 1906), in his paper on the genus, considers it onlj- a more slender 

 form of G. f-nuispira, Bs., a view most dillicult to fall in with and 

 support. There is a very considerable difference in general form — 

 that is, when compared with the so-called tenuispira of Sikhim. 

 Mr. Gude credits me with having found it in the Khasi Hills 

 (F. B. Iiid. ii. p. 379), probably on the authority of Geoffrey 

 Nevill, in his Hand-list, p. 170. The Khasi form is quite distinct 

 and described further on. 



In the Beddome collection put up in the same bos are four shells 

 under this name, with two labels in Beddome's handwriting. One 

 has on it (three in pencil) "Daijiling, H. F. Bl.," the other (one 

 in pencil) "Thyet Myo." It is easy to see the difference in this 

 last from the others, the apex is much more attenuate, the aperture 

 larger and broader. The Darjiling shells are quite typical, and I 

 have com]>ared them with Henry Blanford's types. 



G. bacidina was found by Mr. Wm. Robert at Zemo Samdong 

 in Sikhim, some CO miles up the Sikhim Valley — there smaller, 

 28 X 6-25 mm. (No. 553 B.M.) 



Glessttla (Eishetia) BActJLiNA, H. B]f. var. exilis. (Plate 

 CLIX. tigs. 13, 14.) 



Localit)/. Rissom Peak, Sikhim (3595 B.M.) — Type. Damsang, 

 Sikhim (3594) (T!\ liobert). 



Shell elongately turreted ; sculpture : rather close niised 

 striation, oblique ; colour umbcr-brown ; spire long, apes fine.
