varieties in color, size, and, to some extent, shape, of the above. I have 

 examined thousands of specimens and could find no single character in one 

 species, which did not pass insensibly into another. In the raised beaches 

 of S. Austraha it abounds in extraordinary quantities, and is burnt for 

 lime. 



Venus (chione) lamellata. Lamarck, Vol. 6,2J- 349. The most beauti- 

 ful of ovu" bivalves, distinguished by its transverse elevated imdulose frills, 

 which are striate on the lower side, and of pink color, not unlike the gills of 

 a mushroom. Common in Tasmania, and extending, though rarely to Port. 

 Jackson, and S. Australia as far as Guichen Bay. Long. 40, lat. 55, alt. 22, 

 frills 6 at that size. 



Venus (chione) stutchburyi. Ch^ay. 



Venus (chione) roborata. Hanky, Zool. Proc, 1844, ^. 161. Solid, 

 with numerous smooth, concentric, thick ridges, curved inwards, white, 

 broadly rayed vnih. pale pink at times. Common, and S.E.A. Long, and 

 lat. 45, alt. 15. 



Venus (chione) gallinula. Lamarck, Vol. 6, p. 348. Cordately 

 elliptical, elegantly and closely covered with stout recurved ribs, margin 

 finely dentate, whitish, sometimes rayed with sharply angulate red lines, 

 interior of a uniform violet purple. Common, and V. Long. 30, lat. 39, 

 alt. 20. 



Venus (chione) macleayana. Tenison- Woods. 



Venus (chione) striatissima. Sowerby, Thes. Conch., i^l. 157, fig. 103, 

 tic. Small, oblong, ovate beautifully sciilptured with radiating ribs and 

 transverse lamellse ; mottled with red and brown. D'Entrecasteaux's 

 Channel, W. Legrand, and in S.E.A. Long. 8^, lat. llj, alt. 5. 



Venus (chione) australis. Soiuerhy, Zool. Proc, 1835, p. 22. Like a 

 Corbis, nearly latticed, fawn color with brown rays, differing from the last 

 in the size, closeness and thickness of the lamellae, which are also recurved. 

 Long. 10, lat. 28, alt. 12. These dimensions agree with Sowerby's, but the 

 N.S. Wales and S.A. specimens are much smaller. Rare. B.Sts. and S. 

 Coast. 



Venus (chione) scalarina. Lamarck, Vemis nitida, Quoy. A variety 

 of V. conularis only. q.v. 



Venus (chione) l^vigata. Sowerby, Thes. Conch., pi. 159, p. 156. 

 Smooth, shining, ovate, acuminately produced posteriorly, and grooved ; 

 dusky fawn, with two or three smoky broad rays. Rather common, V. as 

 far as Portland Bay. Long. 26, lat. 39, alt. 18. This is the measurement 

 of specimens taken on the E. Coast, Elsewhere it is smaller. 



Venus (chione) fumigata. Sowerby fas Tapes). Is only a large dusky 

 variety, the posterior grooving being either present or absent on different 

 specimens. 



Callista diemanensis. Hanley, Zool. Proc, 1844, p. 110. Oblong, 

 ovate, solid, rather variable in color, but generally fulvous bay, more or less 

 rayed with ashy purple. Hanley says it is easily distinguished by the ashy 

 purple ray under the umbones inside ; this, however, disappears with age. 

 Long. 24, lat. 33, alt. 15. This species was described by Deshayes (Brit. 

 Mus. Cat. Conch., sp. 25, p. 64) as new and named i)wwe multistriata, under 

 which name, but as Callista, it is quoted as a New Zealand shell by Hutton 

 (Cat. Mar. Moll. N. Zealand). It is found sometimes double the size 

 given, and then the colors are very pale. 



Callista planatella. A fiat shell described by Lamarck from specimens 

 in his possession, but previously described by Chemnitz, Conch. Cat., 7, t. 43, 

 litt. B ? (sic in Lam). Said by Philippi (in Abbild Conch., p. 199, yl. 3, 

 fig. 6) to come from "Terra Van Diemanensis," which may refer to N. 

 Australia. Deshayes (Brit. Mus. Cat. Conchif., part 1, p. 69) doubts if the 

 shell is the same. Unknown in Tasmania.
