to the same habitat. 
Of the two names C. bimaculata is to be preferred because the 
diagnosis is accompanied by figures. | 
[Genus Myuirra, D’Orbigny and Recluz. 
Our species quoted under Pythina should be transferred to the 
above-named genus; as according to Mr. E. A. Smith, Annals 
and Mag. Nat. Hist., 1891, p. 227, Pythina is restricted to 
P. Deshayesiana, Hinds, and differs from Kellia only by its 
divaricate plications.

Smith says that this species “is identical with the preceding ” ; 
but this I think is a very hastily-formed opinion, and I doubt 
if he has seen the shell or giving attention to the figure or 
description of it. :

A single specimen obtained by Mr. Adcock at Hardwicke Bay 
is larger and less rotund than examples comparable with the 
types. This variety is figured by Smith, as above quoted, who 
remarks ‘the specimens from Bass Strait exhibit a precisely 
similar outline (to the figured example from Port Jackson), and 
consequently approach very closely to K. cycladiformis of New 
Zealand; and, indeed, I am rather inclined to believe that they 
will prove eventually variations of one and the same species.” |
