MALAYSIAN LAND AND FRESHWATER MOLLUSCA, 
Shells belonging to the Indian region amounting to about 30- 
species, but some of uncertain position, which extend to New 
Zealand, Lord Howe’s Island and Australia. The family may be 
said to be represented partly in southern Asia and its islands. 
Animal with long and filiform tentacles, with sessile eyes on 
the posterior base ; foot short. The name of the genus refers to 
two lobes on each tentacle at the base behind, on each of which 
there is an eye. The species abound in masses of decayed 
vegetable matter, or under stones m damp situations, and beneath 
trees on the shady sides of mountains. I found a good many on 
a dead tree which had been felled in the clearing of a coffee 
plantation. At daybreak in the morning I generally found one 
or two walking about. This was probably D. mirabilis. The 
genus Paxillus is founded on a smooth I’eversed species from 
Borneo.
