to be Australian. 
6, 7. U. Sikkimensis, Lea. See Plate XI. f. 4. 
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.

By some error the longitudinal brown marks (in 
the type) were described as spiral.

We have seen only two examples of this shell, which 
seems to have been delineated in Lister’s Hist. Conch, 
pi. 116, f. 11 : they resemble the M. aspirans, var. of 
Reeve (C. Icon. Mel. f. 53, b.) but are not like the 
types of Hind’s species.
