Original description :—* Testa lenticulari, subdepressa vix umbili- 
cata, acute carinata, tenue striata, translucente, colore stramineo, polita, 
peristomate acuto; anfractibus 53-6 ; magnitudinis 1-40—0-55. 
** Habitat prope Teria ghat, ad pedem montium Khasia dictorum. 
‘This shell is a very distinct species, of the same form as the 
above, from which it differs in sculpture, want of solidity, and colour. 
“‘ As far as I can judge, its habits are arboreal, whilst the last 
species affects rocks in company with H. oarytes.”

“This appears to me a variety of Mr. Theobald’s species, differing 
only in the last whorl being a little narrower. Mr. Theobald’s type, 
of which I have a specimen, is from Teria Ghat on the south side of 
the range. Major Godwin-Austen’s specimens are from the north 
side.” 
Nongkulong is on the south side of the range and about forty 
miles to the west of Cherra Punji. I had been surveying also on 
the north of the range, and had forwarded many shells from there,
