to be Australian.

Assam. 
This species, formerly so scarce, had been previously 
figured by us from an uncharacteristic example. The 
large variety (fig. 7) reminds one externally of Wyne- 
gungaensis.

We have seen only two examples of this shell, which 
seems to have been delineated in Lister’s Hist. Conch,

Reeve (C. Icon. Mel. f. 53, b.) but are not like the 
types of Hind’s species.
