54 LAND AND KRKSHWATKK 



Pegu and Durjiliiig; four were ccrtairil\- from tlie latter place, but 

 one was cjuite a different species and smaller, and may have come 

 from Pegu. 



Nevill gives the Garo Hills on two specimens from my collection ; 

 this cannot be an accurate determination, as I have nothing like 

 it. The ten specimens from Assam are something else. 



Recently (July 1917) further material has come to hand: when 

 going through \Vm. Blanford's collection of duplicate shells, I came 

 on four pill-boxes containing Glessula from Pegu, with true locality 

 and named as follows : — 



No. I contained AeJiatina tenuhpira from Bassein District, 14 

 examples; No. 2 from Akouktoung, IS examples; No. 3 Achalina 

 }>t'rtenuis from Tongoop, which is on the Arakan Yoma, 8 examples ; 

 No. 4 "intermediate between ii-iiuispira awd j)erie)miii " from Pyema 

 Ivhyoung, Bassein District, 2U examples. These clear up doubts 

 on distribution and show .so well what Blanford's views were at 

 the time he was describing Pegu Glessulas. No. 4 is G. Ixisseinensis, 

 described further on. No. 2 dift'ers from this in many respects, 

 due, no doubt, to its habitat on the Limestoue rocks, which the 

 name implies, " Akouk " being lime and "toung" a hill in 

 Burmese ; I remember the place well. I adopt it as the specific 

 name. No 1 is a well-defined species differing from the preceding, 

 which I name G. nnthiana. from the Burmese name " nath " for 

 spirits or fairies of woods and hills. 



Glesstti.a basseinensis, n. sp. (Plate CLXIY. fig. 12, apes ; 

 Plate CLXI. fig. 3.) 



Lornlitii. Bassein, Pegu, three specimens. Pyema Khyoung, 

 Bassein, six specimens (^ TF. T. Blanfurd). Type. No. 10.9.3.10 

 B.il. 



Shell elongately turreted ; sculpture close, fine, regular, rallier 

 coarse; colour ochraceous; spire elongate, sides nearly straight, 

 very slightly acuminate near the blunt apex, 100: 33'7 ; suture 

 moderately impressed ; whorls 11, fides very fially convex ; aper- 

 ture narrowly ovate; columellar margin cnrved slightly. 



Size: major diam. 0'25 ; alt. axis 25'0 mm. 



This is the var. major o^ iiertenuis Blanford alluded to above ; it 

 is not so attenuate in general form, the apex is much stronger 

 and blunter, fewer whorls, white, longer, and the sculpture 

 coarser; a comparison of figure (No. 3) with those of true ienui- 

 s/nra from Teria Ghat and liusUda shows, better than any 

 description, how much it differs.
