86 LAND AND FRESHWATER 
Size: major diam, 6-4 mm., alt. axis 3°6 mm. 
= 0°25 inch,~ ,, 0-14 inch. 
Not so open at the aperture, and columellar margin straighter and 
rather more rounded below than in the type. 
MAcROcHLAMYS NENGLOENSIS, n. sp. (Plate XVII. fig. 3.) 
Locality. Nenglo, Naga Hills (H. H. G.-A.). 
Shell perforate, globosely conoid, somewhat flat on the base, 
slightly subangulate ; sculpture smooth, with irregular wavy 
distant ribbing ; colour pale olivaceous green; spire conoid, rather 
high, sides slightly convex, apex blunt ; suture shallow; whorls 6, 
regularly increasing, flatly convex; aperture narrowly lunate ; peri- 
stome thin, oblique to axis on columellar margin, and considerably 
reflected. 
Size: ae diam. 5°3 mm., alt. axis 3-1 mm. 
0-21 inch, oo O22 inch: 
This shell is closely allied to MW. longicauda, but is more globose, 
with more convexity on the side of the spire; the aperture is nar- 
rowly lunate, and the columellar margin is stronger. This shell I 
considered at first to be the same as Heliw poongee, Theob., from 
Moulmain ; but a comparison of specimens from that locality in Mr. 
W. T. Blanford’s collection shows the sculpture to be very different, 
and there is considerable difference in size and form. 
MaAcrocHLaMYs NENGLOENSIS, var. (Plate XVII. fig. 5.) 
Locality. Munipur (H. H. G.-A.). 
Shell tumid and rounded below; sculpture none, a few lines of 
growth, surface like ground glass ; colour pale umber-brown ; spire 
conoid; whorls 6; aperture semilunate; peristome thin, oblique 
near axis, scarcely reflected. 
Size: major diam. 5-1 mm., alt. axis 3:1 mm. 
0:20 Hilde 39. 0:12 inch. 
Principally ‘differs in the aperture being wider, a weaker colu- 
mellar margin, and not so flat on the base. 
I obtained a specimen of this species in the Umiam valley near 
Shillong, which I find described in my note-book as follows :— 
“ Sculpture none, but the epidermis like roughish paper, crossed 
with microscopic lines irregularly. 
“Animal. Length 0°33 inch; tentacles nearly 0:1. Dark greyish 
brown, and ridge of foot of same colour. Foot beneath white. 
Body long and tapering, with a mucous pore at the extremity of the 
foot. Shell of a dull pale-brown colour when containing the living 
animal. By suddenly contracting its body, the animal can throw 
itself off the position it may be on, after the manner of Helicarion 
salius and other species of that genus. 
MACROCHLAMYS KOLIAENSIS, n. sp. (Plate XVII. fig. 6.) 
Locality. Koliaghur, low hills on Brahmaputra, Nowgong District, 
Assam (H. H. G.-A.).
