Specleii of Liviopsis. 425 



With regard to L. forskali, this shell was described by Adams 

 from recent examples (dead shells), from the shores of Japan.i 

 No figure of the species was given, and, although the description 

 agrees in many particulars with the present form, the Japanese 

 shell differs in having the radial riblets alternately large and 

 small, whereas the radii in the fossil species shows every grada- 

 tion between simple primary riblets and intermediate riblets 

 from 1 to 4 in number. In the absence of authentic specimens of 

 L. forskali, and bearing in mind the difference in ornament 

 noticed above, it appears safer to designate our common 

 Kalimnan species by a distinctive name. 



The examples of L. beaumariensis from the Kalimnan series of 

 Grange Burn and McDonald's, near Hamilton, are generally much 

 abraded and ironstained, and in some cases the shell surface is 

 80 highly polished as to show that they have been undoubtedly 

 subjected to wind erosion. 



Distribution. — The distribution of the above species does not 

 coincide with that of L. forskali as recorded by Dennant and 

 Kitson2 in their Barwonian group of localities, since the former 

 author had compared L. belcher i (=L. maccoyi, sp. nov.) with 

 that form {teste Dennant Coll.). 



Barwonian. — Lake Bullenmerri, Camperdown. G.S.V. coll. 



Kalimnan. — Beaumaris ; McDonald's, Muddy Creek ; For- 

 syth's, Grange Burn ; Jemmy's Point. Gippsland (in Dennant 

 coll. as " '] Limojfsis insolita, var.").
