over, the shell to be an adult because of the thickened lips, 

 overlooking the fact that Trivia, unlike Cyprcea, exhibits no 

 shell-metamorphosis. 



An examination of many small examples of T. avellanoides 

 permits me to state that the smooth dorsal area does not 

 begin to develope until the shell has reached a length of 

 about eight millimetres. 



Localities. — Table Cape, Jolmston. Balcombe Bay and 

 Muddy Creek, Victoria ; Eiver Murray Cliffs, near Morgan ; 

 Aldinga Cliffs; and bore-hole at Adelaide, U. Tate. 



Syrnola bifasciata. 



Meference. — Tenison- Woods, Proc. Roy. Soc, Tasmania, 

 1875, p. 145. 



This recent Tasmanian gastropod-shell has been identified 

 by the author of the species as a fossil in the Table Cape 

 beds (loc. cit., 1876, p. 99). The species is unknown to me. 



EULIMELLA SUBTJLATA. 



This name was applied by Tenison- Woods to a fossil from 

 the Table Cape beds, an example of which, received from Mr. 

 R. M. Johnston, I forwarded to Mr. Gwyn Jeffreys for com- 

 parison, who most authoritatively states iu to be a different 

 species, and which I propose to name Leiostraca Johnstoniana. 



Natica polita. 



Reference. — Tenison- Woods, Proc, Roy, Soc, Tasmania, 

 1875, p. 23. 



Originally described as a Table Cape fossil. It has since 

 been found living off the Tasmanian coast (loc. cit., 1877, 

 p. 32). I have nut seen recent examples of this species. 



Ceossea labiata. 

 Reference. — Tenison- Woods, Proc. Roy. Soc, Tasmania, 



1875, p. 151. 



This living Tasmanian shell has been recognised as a Table 

 Cape fossil by Mr. R. M. Johnston (op. cit., 1880, p. 41;. I 

 have not seen a fossil specimen, but an allied species occurs 

 fossilised at Adelaide, River Murray Cliffs, and Muddy Creek; 

 it is much larger and the outer lip is simple, not varicosed as 

 in C labiata. If the Table Cape specimen be immature, or 

 have a mutilated aperture, its identification cannot be reliable.
