1070 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 i-efers 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 in 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 J), mirahilis. The 

 genus Paxlllus is founded on a smooth reversed species from 

 Borneo.
