Turbonilla angasi. 



Turbouilla macleayana. 



Turbonilla mariae. 



Turbonilla tasmanica. From further careful examination of 

 the type this is certainly Truncatella scalarina in the 

 undecollated state ; the specimens are very white. 



Aclis tristriata. 



Bittium minimum. 



Ceritniopsis tasmanica. 



Triforis tasmanica. 



Triforis tasmanica. Yar. A. The specimen is broken, but 

 what remains shows it to be T. pfeifferi Cr. and F. 



Diala punctata. 

 Diala tessellata. 



Diala tumida. The shell figured as snch in Tate and May, 

 Fig. 67, is uot this species ; the type shows it to be 

 closer to Rissoia olivacea of whish it may be a variety ; 

 it is longer, with flatter whorls and fewer ribs than is 

 shown by typical olivacea from 

 Port Jackson. The type is much 

 beach worn. 



Fossarus bulimoides. The type is a 

 juvenile example of Adelacieon 

 casta. A. Adams. 



Fossarus tasmanicus. 



Cingulina austrahs. 



Littorina hisseyana. 



Rissoina St. Clarse. 



Rissoina flindersii. 



has been wrongly united with 

 Diala pagodula by Tate ; first 

 in his " Revision of the Re- 

 cent Rissoidse of Australia," 

 T.RS.S. Aus., 1899, and 

 similarly in Tate and May 

 Census, p. 388. An examination of the type shows it to 

 be a Rissoia of the section Amphithalamvs, the mouth 

 being quite characteristic, and entirely different from 

 Diala. I have examples of the species from South 

 Australia. Fig. 8. 



Rissoina gertrudis. See Notes on Tasmanian Conchology, 

 1902. C. Hedley. 



Rissoina concatenata. Type badly broken, 



Rissoa cyclostoma.
