NOTES ON THE CONCHOLOGY OE KING GEOKGE'S 



SOUND. 



During a recent visit to King George's Sound, Western 

 Australia, my friend and colleague, Professor John Davidson, 

 was kind enough to gather for me about a gallon of very coarse 

 shell sand. The gathering has yielded thirty-eight species of 

 mollusca, and as some of them are new and others not known 

 to occur so far to the west, I have thought it worth while to 

 place on record the following observations :— 



King George's Sound is classic ground to the conchologist, 

 as many of the earlier known Australian shells were obtained 

 at this place. It was visited by the Erench surveying ship, 

 commanded by Peron, and twenty-eight of the species then 

 collected were described by Lamarck in his " Animaux sans 

 Vertebres," 1818-1822. Its waters were again explored by a 

 Erench surveying ship, the Astrolabe, and thirty-seven species 

 then obtained were described by Quoy and Gaimard in the 

 Zoological account of the voyage (1830-1833). Menke, in his 

 " Molluscorum Novae Hollandia?," 1843, describes and refers to 

 185 species as belonging to Western Australia, some of which 

 are recorded as inhabiting King George's Sound. These are 

 the chief sources of information having reference to the marine 

 shells of the west and south-western shores of this continent, 

 and I am not aware of any attempt made to furnish a complete 

 list of the shells of Western Australia. Of the shells not 

 previously known to occur I record the following : — 



Teophon PAiviE, Crosse. Inhabits St. Vincent's and Spencer's 

 Gulf, and has been collected at Port Elliot. Occurs in 

 New South Wales. 

 Tbophon, species undescribed. Lives in the mangrove-swamp 



about Port Adelaide Creek. 

 Deillia habpttlabia, Desmoulins. St. Vincent's Gulf, 



Lacepede Bay. 

 Bittitjm Lawletanttm, Crosse. Occurs in New South 



Wales, Victoria, Tasmania, and South Australia. 

 Ttjbbonllla eeubescens, n. sp. 

 Aiaba pagodula, Adams. Till now peculiar to St. Vincent's 



Gulf. 

 Diala lauta, Adams. Very common in St. Vincent's and 



Spencer's Gulfs. 

 Diala imbeicata, Adams. Specimens obtained by me from 

 St. Vincent's Gulf have been so named by Mr. G. E. 

 Angas. 

 Captjlus subettscus, Gray. St. Vincent's Gulf. 

 Clanculfs etjbens, Adams. South Australia and Tasmania. 

 Thalotia conic a, Gray. Tasmania, Victoria, and South 

 Australia. Common at Eowler's Bay.
