Glessdla CRA.ssiLAi!Eis, Bs., var. NANA.. (Plate CLXII. fig. 23.) 

 No. 1609 E.M. 



Locality. North Khasi (2 specimens) (Godtoin-Austen). 



Sbell oblong turreted, smooth and shin}' ; sculpture: a few 

 incised lines; colour ochraceous with a green tinge; spire elongate, 

 sides convex, apex blunt; suture impressed; whorls 7, slightly 

 convex ; aperture narrowl}' ovate ; peristome outer lip thickened 

 slightly ; columellar margin short, truncated, rather straight. 



Size: niaj. diam. ;5'8 ; length 8 mm. 



This shell, evidently fully grown, has much the form of O. crassi- 

 lahris, and the sculpture is of similar character, but it is so very 

 much smaller. There being only two specimens it is better to 

 consider them a dwarf variety than to give a specific title. A 

 single s])eoimen was also found in the Jatinga Valley, N. Cachar 

 (No. 3412 B.M.), another on Koliaghur Hill' on the L.B. of the 

 Brahmaputra (No. 35(J7 B.il.), while yet another from the Duusiri 

 Valley, also at a low elevation (No. 3392 B.M.). 



Glessttla ptramis, Bs. (Plate CLX. fig. 24 ; Plate CLXIV.

" Habitat ad Teria Ghat ilontium Khasi. Detesit W. Theobald. 



" Allied to the smaller Ach. crassula, B., from Darjiling, but 

 distinguished from it by its colour, smootlier sculpture, more convex 

 and numerous whorls, by the characters of the peristome, and by 

 the convex and not planate sides of the spire. 



"A large variety of Ach. crassida, collected by Mr. W. T. Blan- 

 ford near Darjiling, is 12 mill, in length by 5| in breadth, aud, 

 like the type, possesses only seven whorls." 



E. pi/ramis is very smooth and glassj-. The largest specimen 

 from Tiria Ghat figured measures 14-5 x 5-75, slightly smaller than 

 the specimen described by Benson. 



In the Beddome collection I found a single specimen (No. 747) 

 named pyramis by Colonel Beddome ; he does not refer to it in his 

 notes on the genus, al. hough its habitat is Ponsee. It measures 

 17 X 6-8 mm. 



This is no doubt the Glessula pyramis, var. major, of Geoffrey 

 Nevill, 6 sp., Ponsee coll. Dr. J. Anderson, vide ' Hand-list,' i. 

 p. 163. In the copy which he gave to me, Xevill has written
