anteriorly, posterio-laterally large and somewhat rhomboidal ; absent on the 
mantle. Caudal mucous pore large and overlapped by the extremity of the 
tail. Peripodial groove faint. Foot-fringe yellowish-brown, lineoles absent ; 
foot-sole same colour, with median and lateral planes.

Hitherto the genus has only been recorded from Borneo. The present 
species differs from D. dilecta^ Issel, the type of the genus, in its smaller size,

position of the visceral mass in relation to the body posterior to it.
