MOLLUSCA OF INDIA. 15 
“This species appears to have escaped the notice of all previous 
collectors in Sikkim ; it was found in association with its near ally 
G'. tenwispira, Bens., by Dr. Stoliczka during a recent visit. It is 
easily distinguished from the latter species by its slenderness (the 
diameter being 4 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. tenuispira, G. erosa, and other allied 
forms, the curvature is at the utmost obtuse. Specimens, the shell 
of which had been slightly weathered, show fine spiral markings, 
but these are not visible unless the shell has become somewhat 
opaque. The animal is dark leaden grey, somewhat paler at the 
sides of the foot. 
“« The following 1s a list of the species now known from Sikhim :— 
G. tenwispira, Bens., G. crassula, Bens., G. hastula, Beus., G. orobia, 
Bens., G. erosa, nob., G. baculina, 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 seen for 46 years. At the 
time I was staying 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 quite a large series obtained since from different localities 
in Sikhim and Western Bhutan. Beddome (Pro. Malacol. Soe. 
1906), in his paper on the genus, considers it only a more slender 
form of G. tenuispira, Bs., a view most difficult to fall in with and 
support. There isa 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. Ind. 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 box are four shells 
under this name, with two labels in Beddome’s handwriting. One 
has on it (three in pencil) ‘‘ Darjiling, 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 compared them with Henry Blanford’s types. 
G. baculina was found by Mr. Wm. Robert at Zemo Samdong 
in Sikhim, some 60 miles up the Sikhim Valley—there smaller, 
28 x 6°25 mm. (No. 553 B.M.)
