Port Lincoln, Kangaroo Island, Aldinga Bay, Edithburgh, 

 Encounter Bay, South-East coast. Banges from south-west 

 Australia to New South "Wales. 



Cordately elliptical, closely covered with thin, erect, short 

 lamellae, elegantly ornamented with brown angular lines on a 

 whitish ground ; length, one and a quarter inches. 



The type of V. gallinula is from King Island, in Bass Straits, 

 whilst those of V. lagopus and V. australis are from King 

 George Sound. Deshayes and other authors keep distinct 

 C. gallinula and O. australis, and both appear in the lists for New 

 South "Wales (Angas), Tasmania (T. Woods), and "West Aus- 

 tralia ; whilst Angas records V. australis only for South Aus- 

 tralia. The few specimens of C. gallinula from the type locality 

 which I have studied are certainly a little higher propor- 

 tionately than our so-called O. australis, but I cannot find any 

 other differential characters. Young shells present much indi- 

 vidual variation in respect to outline, strength of the lamellae, 

 and radial striation, and are inseparable from C. striatissima, 

 Sow. 



(c) Concentrically thinly ridged or striated ; margin of valves 

 plain.

Sandy shores at low tide. Great Australian Bight; Port 

 Lincoln ; St. Vincent Gulf. Also King George Sound (type)

Ovately oblong, with wavy ridges coarsely crenulated; more 

 elongated, less oblique, and flatter than its allies ; length, one 

 and a half inches. 



68. Chione aphrodina, Lamarck (Venus), An. s. Vert., v., 

 p. 605. V. conularis and V. JPeroni, Lamarck. 



Sandy shores at low tide; Great Australian Bight (St. 

 Erancis Isles for type of V. conularis); Kangaroo Island (for 

 type of V aplirodina); St. Vincent Gulf; also King George 

 Sound (for type of V. Peroni) and Tasmania. (Maria Island, 

 Lamar cK). 



More inflated, and rounder than its allies ; transverse ridges 

 plain, broadish, and flat.

 p. 599 ; V. aphrodinoides, Lamarck ; V. nitida, Quoy and 

 Gaimard, t. 84, f. 13, 14, vol. 3, p. 529 (1835). 



Sandy shores at extreme low- water mark. Very abundant in 

 Holdfast Bay — used for food and bait for fishing. It ranges 

 from Swan Biver (Angas) and King George Sound ! to Tas- 

 mania.
