I cannot discern any differences sufficient to separate the 

 Penang and the Bornean shells. A single young example 

 from Bunguran has much the appearance of S. tricarinata'\ 

 from the Nilghiri Hills, India.

Hal. Bunguran [Everett) ; N. Borneo [Everett). 



Three young specimens from Bunguran ai-e indistinguish- 

 able from Bornean examples. S. ])erakensis, Godwin- 

 Austen, is very closely allied and S. angulata^ Issel, is also 

 very similar. 



10. Sitala sirhassenensis. (PI. XVI. fig. 5.) 



Testa breviter conica, carinata, angustissime perforata, tenuis, sub- 

 pellucida, striis spiralibus tenuibus sculpta ; aufractus 54, parum 

 convexi, sublente accrescentes, supra suturam carino-marginati, 

 ultimus ad peripheriam acute carinatus, baud doscendens, infra 

 medium convexiusculus ; apertura augulatc luuata ; peristoma 

 tenue, margine columellari superne retlexo, albo, perpendiculari. 



Diam. 4 miUim., alt. 3-75. 



Hah. Sirhassen. 



The spiral stria? are excessively fine, and, being crossed by 

 equally fine lines of growth, the surface has a minutely can- 

 cellated aspect.
