This species was described from a Table Cape fossil, but the 

 author appended a note, that a living example had been 

 dredged off the Tasmanian coast. 



Having had the opportunity of comparing recent and fossil 

 specimens I found differential characters to obtain such as are 

 set forth in Proo. Linn. Soc, N.S.W., 1878, p. 236, wherein 

 Mr. Woods has applied the name of L. subquadrata to the 

 living species. 



LlOTIA DISCOIDEA. 



The species so named by Reeve is living on the coast of the 

 Philippines, and extends to Tasmania. It has been quoted 

 by Tenison- Woods as a Table Cape fossil, but Mr. Johnston 

 gives valid reasons for rejecting that identification and has 

 described the fossil under the name of L. Roblini in Proc. 

 Roy. Soc, Tasmania, 1880, p. 39. 



L. Boblini is abundant in the Muddy Creek beds, and a 

 few examples have been collected by me from the " gastropod- 

 bed " in the River Murray Cliffs, near Morgan. 



Imperator (Australium) imperialis. 

 This recent New Zealand species is included, with a doubt, 

 in the list of Table Cape fossils, by Mr. R M. Johnston, in 

 Proc. Roy. Soc, Tasmania, 1876, p. 90. 



FiSSXJRELLA CONCATENATA. 



The Rev. Tenison-Woods referred a Table Cape fossil to 

 Crosse's species from South Australian waters, but which 

 apjjearsto be conspecific with Fissurellidcea malleata, niihi, 

 in Trans. Roy. Soc, S. Aust, vol. v., p. 146, 1882. 



Dentalium lacteum. 



" Living in the Indian Seas. This is a doubtful identifica- 

 tion. The fossil is very common, and may be a variety only." 

 Tenison-Woods in Proc. Roy. Soc, Tasmania, 1875, p. 17. 



I have not seen a Table Cape specimen of this species, but 

 a Dentalium common in the Muddy Creek beds agrees well 

 with the figure, measurements, and description given by 

 Deshayes in his monograph of the genus. 



Cylichna arachis. 

 " Still living in Tasmania and Australia, and not uncommon 

 in the Table Cape beds." Tenison-Woods in Proc. Roy. Soc, 

 Tasmania, 1876, ]). 102. The same author, in dealiiii^' with 

 another species from the Miocene deposits at Muddy Creek, 

 refers to it as " one of those specimens which may, perhaps, 

 be identified with Quoy and Gaimard's shell," and then pro-
