Sab. — In montibus JBurrail dictis, ad latus meridionale vallis Assamen- 

 sis, in " North Cacliar," ad alt. circa 6500 ped. angl. detexit H. H. Godwin- 

 Austen. 



This species is well distinguished from its allies by its slender shape and 

 numerous whorls. 



I have a single specimen of a Clausilia from the Arakan hills, somewhat 

 similar to C. monticola, but with only ten whorls. As it is bleached and 

 the surface in bad condition, I do not desribe it. 



Section IV. — Oospira* sect. nov. Shell with but few whorls, usually 

 five or six, and of a peculiar more or less oval form with a very blunt apes. 

 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 type 

 is peculiar to Martaban and Tenasserim.

Sab. — Moulmain. According to PfehTer this shell is also found at Mer- 

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

Sab. — Tavoy (and Moulmain?). 



I have figured a shell from Moulmain which may possibly be this form, 

 as it agrees in its measurements with Could' s type ; but it is barely separa- 

 ble from G. PMlippiana. 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 Barmese and South American Clausilice.
