56 May, Molluscan Fauna of the Furneaux Group, [vor^xxx- 



of Barren Island. A Port Phillip species, Mesodesma nitida, 

 Desh., was common near the settlement, and Chione peronii, 

 Lamk., at Lady Barron, l)oth new records. At Forsyth Island 

 valves of Mactra pura, Desh., and Tapes galaciites, Lamk., were 

 common. These north coast shells have not been recorded for 

 our east coast. Several small species of Marginella occurred 

 here also, which are found down the eastern coasts, but not 

 along the north. Haliotis ncsvosa. Mart., was found there, and 

 was apparently plentiful ; its place was taken at the settlement 

 by H. albicans, Quoy and Gaim., and H. emmcB, Gray, which 

 do not appear on the east coast. A northern form, Stomatella 

 imbricata, Lamk., was plentiful in a rock pool near the settle- 

 ment ; it has not been recorded further east. Thalotia conica. 

 Gray, and Clanculus dunkeri, Koch, were plentiful, and are 

 South Australian forms ; the former is also found at Circular 

 Head, but is not so far known from any other part of our coast. 

 Semele exigiia, A. Ad., was common at the settlement, and this 

 is perhaps its only extra-Australian locality. Three species 

 which here reached a maximum development in size are Tellina 

 decussata, Lamk., Macoma marice, Ten.-Wds., and Patella 

 limbata, Phil. 



The following is a complete list of the species observed, 

 numbering 152 ; no doubt the number could be largely added 

 to by further search : — 



Argonauta nodosa, Sol. — Several specimens seen in local 

 collections. 



Sepia (sp. ?) — A large shell of this genus was very plentiful 

 on the beaches near the settlement. 



Murex triformis, Reeve.— Several dead and one small living 

 specimen seen. 



Trophon goldsteini, Ten.-Wds. — A single living specimen near 

 settlement. 



Trophon petterdi, Braz. — One specimen, Barren I:3land. 



Thais succincta. Mart. — A smoothish form was seen. 



Agnewia tritoniformis, Blain. — A single specimen seen. 



Sistruni adelaidensis, Cr. and Fis. — Fairly common. 



Lotorium quoyi. Reeve. — A few. 



Fasciolaria coronata, Lamk. — Common, but rather small. 



Cominella costata, Quoy and Gaim. — A few seen. 



Cominella lineolata, Lamk. — Common everywhere, and ex- 

 tremely variable in size, form, and colour. The largest were 

 on Babel Island, where they were red-spotted. 



Nassa fasciata, Lamk.— Common at the settlement. 



Nassa jacksonensis, Quoy and Gaim. — Forsyth Island. 



Nassa pauperata, Lamk. — A few seen. 



Nassa paupera, Gould. — A few.
