56 LAND AND FRESHWATER 
In the Blanford Collection (No. 262.06.2.2) are three specimens 
from Arakan, near Tongoop, much larger than the type described, 
being 10x4°8 mm., but they do not differ in any other respect, 
and may be considered a large variety. ~ 
GLESSULA PONSIENSIS, n. sp. (Plate 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; sculpture: none discernible en the two apical 
whorls, slight striz on 3rd regularly, distantly, and finely costulate 
on the 4th; colour pale ochraceous; spire tapering, apex blunt, 
sides very slightly convex; suture shallow; whorls 9, sides flatly 
convex; aperture ovate, vertical; peristome somewhat thickened ; 
columellar margin strong, concave. 
Size: maj. diam. 7°75; alt. axis 20°0 mm. 
This is Stenogyra (Glessula) pyramis, Bs., var. major, of Nevill, 
‘ Hand-list,’ i. p. 169, reterred 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 blanfordiana, Nevill: Ponsee (Dr. J. Anderson). Iam 
able to state that this is No. 85 of Nevill’s « Hand-list,’ p. 171, as 
entered in Geoffrey 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 CLXIYV. fig. 20, apex), 
has been sent me from Calcutta by the Director of the Zoological 
Survey of India, Dr. N. Annandale, 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 CLXLIV. fig. 21, 
apex), and this extends to the whole apex, as in the type (fig. 20). 
As Glessula peguensis has heen referred to as an allied species, I 
compared and figured the apex, which is of very different form 
and sculpture (PI ate CLXIV. fig. 22, apex)—the specimen selected 
being one in the Wm. Blanford Collection from Tongoop, Arakan. 
GLESSULA LIMBORGI, n. sp. (Plate CLXI. fig. 5.) 
Locality. Tenasserim (Ossian Limborq). 
Shell elongately turreted, with shining surface ; sculpture: very
