band round the periphery and another broader one round the nmbilicus, 

 the periphery is obtusely angulate, the spiral rugose sculpture is coarser 

 above, finer and more regular at the base ; 6 moderately convex whorls 

 form a little elevated spire. The nearest relation seems to be Nanina 

 pluto, Pfr., from Cambodja, but it is probably a new species which I do 

 not care to describe from a single example. 



6. Hemiplecta ctmatium, Bens. 

 Perak, without distinct locality (Hungerford). The single speci- 

 men agrees fairly well with the figure and description of Nanina cyma- 

 tiunij known from Penang and Malacca.

8. Macrochlamts, sp. 



Mr. Hungerford found a few dead specimens at Buket Pondong 

 which fairly agree with the form figured by Godwin- Austen (Land & 

 Preshw. Moll. Ind., iv, 1883, p. 110, t. xxvi, f. 4) and mentioned by him 

 as '* M. conse;ptay Bens., small var. ? " from Tenasserim. 



9. Macrochlamts, sp. an nova ? 



A single specimen from Buket Pondong. Small, 3 mill, long and 

 2 high, horn brown, well-polished, probably new. 



There is besides another much smaller species of Macrochlamys 

 and a species of Microcystis, which I have likewise left undescribed on 

 account of the very scanty material.
