AUSTRALIAN LAND SHELLS. 33 
Genus CALLIA. 
1. Cauca sprenpEens. Dohrn. M.C, 
Dohrn, Pro. Zool. Soc. 1862. p. 183. 
Habitat. Lizard Island, N. E. Coast of Australia, 
MacGiilivray. 
Having had an opportunity of examining several 
specimens of this species from the above locality, 
I may remark that, although Dohrn states the oper- 
culum to be normal, it appears to me to differ in 
form and mode of growth from the circular oper- 
culum assigned to the genus Callia; the mouth 
also contributes to furnish sufficient distinctive 
characters for a new genus.
