56 LAND AND FRESHWATER 



In the Blaiiford Collection (No. 262.06.2.2) are three specimens 

 from Arakan, near ToDgoop, much larger than the type described, 

 being 10x4b mm., but they do not difler in any other respect, 

 and may be considered a large variety. 



Glessula poNsiEiN'Bis, n. sp. (I'late CLXIV. fig. 19, apex.) 



Locality. Ponsee, Yunnan. Coll. Indian Museum {Dr. John 

 Anderson). 



Shell oblong turreted, solid, smooth to eye ; apex very rounded 

 with flattened sides ; sculjiluro : none discernible on the two apical 

 whorls, slight stria; on 3rd regularly, distantly, and finely costulate 

 on the 4th; colour pale ochraceous ; spire tapering, apex blunt, 

 sides ver)- slightly convex ; suture shallow ; whorls 9, sides flatly 

 convex ; aperture ovate, vertical ; peristome somewhat thickened ; 

 columeliar margin strong, concave. 



Size: maj. diam. 7"75 ; alt. axis 20'0 mm. 



This is Slenoyyra (Glessula) jii/ramis, Bs., var. major, of Nevill, 

 ' Hand-list,' i. p. 169, relerred to under G. pyramis by me. I am 

 fortunate in getting the type-shells for examination. I always 

 doubted the extension of G. pyramis so far to the eastward, when it 

 had never occurred in the Naga Hills or Munipur, or even Eastern 

 Assam. 



Glessula hlanfordiana,'Sex\W: Fousee (Dr. J. Anderson). lam 

 able to state that this is No. 85 of Nevill's ' Hand-list,' p. 171, as 

 entered in Geofl'rey Nevill's amended copy in his own handwriting ; 

 that he did not at that time consider it had any close relationship 

 to G. peguensis, is shown by the two lines crossed out, and 

 " 6, Loc? coll. W. Theobald," Bhamao, is entered as the habitat. 



The type from Ponsee, Yunnan (Plate CLXIV. fig. 20, apex), 

 has been sent me from Calcutta by the Director of the Zoological 

 Survey of India, Dr. N. Annamiale, with one other example. 

 This type is, I should say, abnormally thickened, particularly on the 

 columella and tip of the peristome. Nevill's description is excellent. 



I closely compared these with the specimens also collected by 

 Dr. John Anderson at Bhamao (Plate CLXIV. fig. 21, apex), six in 

 number, and made drawings of their respective species, which show 

 considerable variation not amounting to specific difference. 



The sculpture of the Ponsee shell is distinctly costulate, while 

 it is very finely so in those from Bhamao (Plate CLXIV. fig. 21, 

 apex), and this extends to the whole apex, as in the type (fig. 20). 



As Glessula 2>«guensis has been referred to as an allied species, I 

 compared and figui'ed the apex, which is of very diflerent form 

 and sculpture (Plate CLXIV. fig. 22, apex) — the specimen selected 

 being one m the Wm. Blanford Collection from Tongoop, Arakau. 



Glessula limboegi, n. sp. (Plate CLXI. fig. 5.) 



Locality. Tenasserim (Ossian Limhorg). 



Shell elongately turreted, with shining surface ; sculpture : very
