West Australia is very closely similar to that of their distribu- 

 tion in Australia as a whole. 



Of important genera, CnemopUtes has one species (C. 

 anstrallsj, Phoracantha has 2, one widely distributed and 

 one peculiar to the island ; and Pseudocephalus, a genus 

 represented in Chili, has one species in Tasmania another in 

 Victoria and a third in W. Australia, In the Lamiid2e, 

 Zygocera, which, again, is represented in Chili, has one 

 species ( Z. ccenosn) common to Tasmania, Victoria, S. 

 Australia and New South Wales, whilst the large genus, 

 Symphyletes, is unrepresented in Tasmania and has only one 

 species in Victoria. 



The Chr y some lid (P form a family well represented and 

 widely distributed in Australia which, together with Tas- 

 mania, has 124 genera and 984 species, Tasmania having 

 only 15 of these genera and 59 species, there being no genera 

 peculiar to the island but 45 species. The large genus 

 Elapliodes, with 96 species, has only 3 in Tasmania which 

 are peculiar to it. Tomyris with 6 species has 3 peculiar to 

 Tasmania, 1 to New South Wales, 1 to Queensland and I to 

 North Australia, with no representative recoi'ded from 

 Victoria. The extensive and well-distributed genus Paropsis, 

 with 270 species in Australia and Tasmania, has 27 in the 

 latter, of which all but 3 are peculiar and of these 2 are 

 common to Victoria and I to S. Australia. 



MOLLUSCA. 



In this group we will deal only with the land and fresh- 

 water forms. Of Australian workers on Molhisca we may 

 mention especially the names of Professor Tate and Messrs. 

 Cox, Brazier and Hedley, whilst in recent years Mr. 

 Edgar Smith, of the British Museum, has ])ubhshed an 

 important list of Australian fresh-water shells. In Tasmania 

 we owe much to the labours of Messrs. Legrand, Petterd, 

 Johnston and Beddome, and in New Zealand to Professor 

 Hutton. We are still much in need of a monograph 

 dealing with the soft parts of the aninnUs as well as with the 

 shells. A few of our v/orkers, such as Messrs. Hedley, 

 Cox, Johnston and Petterd have done something in this 

 direction but this branch of the work has been too much 

 neglected. 



(1.) Land Mollusca. — In land shells Tasmania is com- 

 paratively rich and its forms have been well collected and 

 described. We can scarcely say the same of Victoria but
