This species is well distinguished from its allies by its slender shape and 
numerous whorls. 
I have a single specimen of a Glausilia from the Arab an hills, somewhat 
similar to C. monticola, but with only ten whorls. As it is bleached and 
the surface in had condition, I do not desribe it. 
Section IV. — Oospira,* sect. non. Shell with but few whorls, usually 
five or six, and of a peculiar more or less oval form with a very blunt apex. 
Lunule wanting, palatal plaits as in Phcedusa. Type C. Philippiana, Pfr. 
The known shells of this section are solid deeply coloured Clausilice, 
smooth or with very slight sculpture. So far as is hitherto known, the tj pe 
is peculiar to Martaban and Tenasserim.

gui, but I have never seen specimens from the latter locality.

Hab. — Tavoy (and Moulmain ?). 
I have figured a shell from Moulmain which may possibly be this form, 
as it agrees in its measurements with Gould’s type ; but it is barely separa- 
ble from C. Philippiana. Gould’s description is so meagre that, it is very 
difficult to identify the species, and it has never, so far as I am aware, been 
figured. 
The shell here represented has a most astonishing resemblance to Clau- 
silia Bartletti, H. Adams, Proc. Zool. Soc. 1866, p. 441, PI. XXXVIII, fig. 
2, from Peru. We shall presently see that this is not the only instance of 
resemblance between Burmese and South American Clausilice.
