DUTCH BORNEO-EXPEDITION. 155 



The nearest allied species, as far as concerns shape, 

 seems to be Nanina (Dyakia) Janus, as figured by v. 

 Martens (Ostas. Landschn. pi. 11, fig. 4), but the last 

 whorl in that species is broader, the upper margin of the 

 aperture is consequently longer and seems to be less curved , 

 and the sculpture is different.
