for it. I, therefore, propose to replace Ampullarina of authors, 

 not Sowerby, by Salinator. 



DlPLOMMATINA OREADIS, n.Sp. 



(Plate xxv., fig. 22.) 



This shell much resembles D. obesa, Hedley,f from New Cale- 

 donia, and can best be described by comparison with it. The 

 Queensland shell is without the auricular expansion of the 

 periphery, has twice as many lamella?, and is narrower than the 

 New Caledonian species. D. oreadis is 1 '8 mm. long and *9 mm. 

 broad. The only specimen I have seen was collected by the late 

 C. E. Beddome, 20 miles inland from Card well, Queensland; it 

 will be preserved in the Australian Museum.
