Obs. The name Melania area occurring in Mr. Daintree’s “Notes on the 
Geology of the Colony of Queensland ” is probably a misprint for the above species.

,, pagoda, Daintree (non Lea), Quart. Journ. Geol. Soo., 1872, xxviii., p. 274. 
Obs. There appears to be much variation in size and appearance, both in the 
living and fossil individuals of this species, especially in form and stoutness, whilst a 
few of the fossils are more elongate than any of the recent examples in the British 
Museum. The former certainly appears to have grown to a larger size than the latter. 
This is probably the species recorded in Mr. Daintree’s Paper as Melania pagoda, which 
is not known as an Australian living species.

Melania maesta.
