THE VICTORIAN NATURALIST. 117 



SOME PAL^ONTOLOGICAL NOTES. 



By G. B. Pritchard, F.G.S. 



(Read before the Field Naturalists' Ghih of Victoria, lOtJi Sei^t., 1906.) 



Certain species that have come under my notice lately require 

 some reconsideration, so I have thought it advisable to embody 

 my observations in the following notes : — 



Turbo grangensis, nom. mut. 



1904. Turbo hamiltonensis, Pritchard (non Harris, 1897). 

 Proc. Roy. Soc. Vic, vol. xvii., n.s., pt. i, pp. 

 329. 330. Pl- i9j f- 4- 



Loc. — Upper beds of the Grange Bum, near Hamilton, 

 Western Victoria. Kalimnan — Miocene. 



Obs. — When describing and naming this species I omitted to 

 remember that Mr. Harris, in his British Museum " Catalogue of 

 Australasian Tertiary Mollusca," had already used this name, 

 Turbo hamiltonensis, for a distinct species from the lower beds of 

 Muddy Creek. I regret the possibility of confusion arising from 

 this mistake, and take this opportunity of changing the name of 

 my species. The species I described is of the type of T. undu- 

 latus, Martyn, but may be distinguished from that species by its 

 sculpture, small umbilicus, and stout columella ; while the 

 species described by Mr. Harris is a close ally of T. etheridgei, 

 T.-Woods. 



Chione roberti, nom. mut. 



1 901. Chione hallii, Tate (non Pritchard, 1895). Trans. 

 Roy. Soc. South Aust., vol. xxiv., pt. 2, p. 107, 

 pl. 2, f. 5. 



Loc. — West side of the Cat's Ears, Kerguelen Island. 



Obs. — In 1895, i" ^ paper to the Royal Society of Victoria, 

 entitled " Contributions to the Palaeontology of the Older Ter- 

 tiary of Victoria — Lamellibranchs, Part I.," I named one of our 

 fossil bivalves from the Spring Creek beds, near Geelong, after 

 Mr. T. S. Hall as Chione halli. Subsequently, in 1900, when 

 Professor R. Tate was dealing with a collection of fossils from 

 Kerguelen Island made by Mr. Robert Hall, he paid that gentle- 

 man the compliment of naming some of the species after him, and 

 amongst these may be noted Chione hallii, unfortunately over- 

 looking the fact that that name was already preoccupied. So 

 that Mr. Robert Hall may still have the credit of having obtained 

 this collection, I take the liberty of renaming the Kerguelen 

 shell as Chione roberti. 



DiPLODONTA BALCOMBENSIS, HOm. mUt. 



1887. Diplodonta subquadrata, Tate (non Carpenter, 

 1855). Trans. Roy. Soc. South Aust., vol. ix., 

 Lam., pt. 2, p. 147, pl. 14, f. loA, JOB.
