26 LAND AND FRESHWATER 
GLESSULA NEVILLIANA, n. sp. (Plate CLXI. figs. 11, 12, 13; 
Plate CLXIV. fig. 3, apex.) No. 449. Type. 
Locality. Toruputu Peak, Dafla Hills (4 specimens) (Godwin- 
Austen). 
Shell elongately conical; sculpture, coarse somewhat irregular 
striation; colour: two ruddy, two dull ochraceous; spire high, 
apex blunt; suture impressed ; whorls 9, sides flatly convex ; 
aperture narrowly ovate; peristome thin ; columella rather straight, 
curved, short. 
Size’: Type -:2, seas: maj.diam. 5:0 length 17-0mm. whorls 9. 
Nevill gives for specimens in Indian Museum :— 
maj. diam. 4:0 length 13-0 mm. whorls 8. 
Small ruddy sp. (fig. 13) a 4-0 ce elder 
Large sp. with apex 
broken .......... . » 50 4 140,, 
7 whorls left (fig. 12). 
In this last, from last suture to base of aperture 7 mm., as against 
54 in the Type. 
This species is recorded by Nevill in his revised copy of the 
‘Hand-list,’ opposite page 170, as ‘* Stenogyra (Glessula) austeniana, 
Nevill—whorls 8, length 13, diam. 0 mm., one Toruputu, Dafla 
Hills (Type), coll. Godwin-Austen.” The specimen thus named is 
probably in the Indian Museum. I cannot find that it was ever 
published: therefore it is now named after my old friend. His 
early death was a great loss, for he possessed a great knowledge 
of Indian Mollusca, and had made a close study of the genus 
Glessula. 
GLESSULA DIKRANGENSE, n. sp. No. 448 B.M. (Plate CLX. fig. 7.) 
Locality. Toruputu Peak, Dafla Hills—in primeval forest. Type. 
( Godwin-Austen.) 
Shell elongately turreted; sculpture very fine and close regular 
striation ; colour ochraceous with a strong green tinge; spire long, 
sides very flatly convex, apex blunt; suture impressed; whorls 9, 
convexity of side very slight; aperture oval, vertical ; peristome 
strong; columellar margin curving. 
Size: maj. diam. 7°75; length 19-0 mm. 
In a paper on “‘ The Helicide of the Dafla Hills ” (Jour. Asiat. Soe. 
Bengal, vol. xlv. pt. ii. 1876, p. 815) L included Glessula illustris, 
the type of which was found on Heugdan Peak in the Naga 
Hills. This was a hasty determination; after a far more critical 
one, and a comparison of the photographs of both, it shows con- 
siderable difference, sufficient to constitute a new species. ‘The 
proportion of the last whorl to the length of the axis is very 
different to that of typical G’, dl/ustvis—taking the axis as 100, it 
is 100:52.
