19 18.] H.H.Godwin-Austen: Mollusca, IX. 615 



This species is placed in Chloritis by Mr. Gude {Faun. Br. India, 

 p. 172), its generic position is very unsettled. I leave it with 

 doubt where StoHczka placed it, he describes under delihrata the 

 animal of a Moulmein shell in J. AS B., 1871, p. 225. The shell 

 Benson described came from Bengal, and it is the animal of this 

 which now requires examination. The generic position of delihrata 

 would then be better understood particularly if other closely allied 

 species were dissected and compared with it. 



Trochomorphoides acris, (Bs.), var. 



Locality.— Ahor Hills {Captain G. F. T. Oakes, R.E.) 



Shell narrowly urabilicated, trochifortn, flat on base, sharply 

 keeled ; sculpture oblique fine striation, transverse ; colour bleeched. 

 Spire high, conoid, sides distinctly concave, apex blunt, suture 

 hnear. Whorls 7, flat; aperture very oblique, narrowly ovate; 

 peristome expanded and slightly reflected below; columellar 

 margin oblique. 



Size: major diameter ii'o, alt. axis 90 mm. 



Two specimens were received, one young and broken, the 

 other fortunately fully grown. The slight convexity of the side of 

 the spire distinguishes this from T. acris, the finest specimens of 

 which I have from South Sylhet, the largest measures major 

 diameter 11, alt. axis 10 mm. 



Curvella ? 



A single specimen was received from Captain Oakes, but is 

 too immature for description, it is not allied to C. sikkimensis, 

 the apex being much more acute. It is unfortunate that Hapalus 

 cannot stand for this eastern section of shells approaching Opeas 

 having been used for a genus of Coleoptera. Mr. Gude in Faun. 

 Br. India, p. 348, following Pilsbry, adopts Curvella, the type of 

 which is an East and South African species, sulcata. From a 

 zoo-geographical point of view, it does not appear to me likely 

 that a genus adapted to a country comparatively dry and of no 

 great attitude, like East Africa, will possess characters similar to 

 one ranging to 10,000 feet and more in an extremely wet, forest- 

 clad country. I have examined the animal of C. sikkimensis , onh'- 

 a comparison of its anatomy with that of the African species can 

 settle the question. 



Glessula oakesi, 11. sp. 



(Text-fig. 8). 



Locality. — Abor Hills {Captain G. F. T. Oakes, R.E.) 

 Shell oblong turreted, shining surface; sculpture regular some- 

 what distant incised lines; colour ochraceous, one umber brown; 

 spire high, sides very flatly convex ; suture impressed ; whorls 7, 

 flatly convex, proportion of bod}- whorl to length 100: 62'5 ; 

 aperture rather narrowly oval, peristome outer lip thickened, 

 columellar margin slightly convex.
