Truncatella tasmanica. Tenison- Woods. Bass' Straits. 



Trochita CALYPTR.EPORMIS. ZamavcJc, Vol. 7, p. 627 (Trochdla, Gray^ 

 Zool. Proc, 1867, p. 735). Spirally much convoluted, with velvet-like 

 periostraca ; white, tinged purple inside. 



Amalthea conica. Schumacher Essai, d'un Nouveau, Syst. des Habita- 

 tions des Vers, testaces, Copenhagen, 1817,2?. 181, also pi. 21, Jig. 4, a, b, c. 

 Common. Parasitic on other shells, and varying much in form and color. 



CocHLOLEPAS FOLiACEA. Quoy, loc. cit., Vol. 3, plate 72. 



CocHLOLEPAS suBRUFA. Soiv. Very plentiful at low water, Tamar 

 Heads. 



Nerita atrata. Quoy, Voy. de VAstroL, pi. 65, %. 41 and 42. A black, 

 rounded species, common in all extra-tropical Austraha. N. Coast of 

 Tasmania only. Long. 21, lat. 24. This sheU has been identified with 

 N. atrata, Chem., which is said to occur in the Atlantic within the tropics. 

 Gray, in the Appendix to King's Voyages, probably originated this. Reeve 

 gives New Zealand as habitat. Many authors speak of a blackish Nerita 

 from those islands, but the specimens I have seen are not different from N. 

 punctata, a S. American species, with which E. Von Martens identifies our 

 AustraHan shell. Very common in Portland, Victoria. 



Phasianella tritonis. Chemnitz, Conch., Cat. 9 to 120, figs. 1033-34. 

 The common pheasant shell of the Southern Coasts of Austraha and all 

 Tasmania. It attains to a large size and varies exceedingly both in shape 

 and color. From this fact many of the species created are surely no more 

 than varieties. Long., in the largest specimens, 9, lat. 39. 



Phasianella venusta. Reeve, Icon., pi. 2, fig. 2. A variety only. 



Phasianella sanguinea. Reeve, Icon., pi. 3, fig. 3. A sohd shell of five 

 rounded whorls. Bright red with pale zigzag lines shaded with brown. 

 Long. 40, lat. 25, but sometimes larger. B. Sts., but common in S.A. 



PHASLA.NELLA ZEBRA. Gray, Rctvc, pi. 3, fixf. 4. Only a variety of the 

 last with broad diagonal bands. 



Phasianella venosa. Reeve, pi. 3, fig. 5. A rare variety with brown 

 banded hnes on a lighter ground. 



Phasianella VENTRicosA. Q,uoy, Voy. deV A strol.,pl. 59, figs. 8 and 9. 

 Another variety. King's Island. Rare. 



Phasianella reticulata. Reeve, pi. 3, fig. 7. A rare reticulated variety, 



Phasianella angasi. Jour. Conch., 1864, p. 344, pi. 13. A small, narrow, 

 reticulated shell. Very rare. The identification in Tasmania is doubt- 

 ful. S.A. 



Phasianella rosea. Angas, Zool. Proc, 1867, p. 114. A minute, thin, 

 shining species of uniform rose color. Long. 2, lat. 1 J, whorls few. In 

 sand from islands in B. Sts., and Blackman's Bay. W. F. Petterd. 



Phasianella delicatula. Tenison- Woods. This shell was described by 

 me in Proc. Tas. Roy. Soc, 1876, as P. pvlchella, but that is the name of the 

 British species. 



Turbo (lunella) undulatus. Chemnitz, Conch. Cat., Vol. 10, pi. 169, 

 fig. 1640, etc. A fine globose umbilicate shell with dark green imdulating 

 lines, nacreous inside. It has a smooth solid spiral operculimi sometimes an 

 inch in length, the shell itself attaining to a great size in S.A. In Tasmania 

 it is smaller. A common fossil in the raised beaches in Austraha, where its 

 numbers and size are extraordinary. 



Turbo simsoni. Tenison- Woods. A doubtful species, possibly yoimg of 

 preceding. 



Turbo (senectus) circularis. Reeve, pi. 10, fig. 46. A non-nacreous, 

 deeply channelled, and granulosely ribbed shell ; color, pink and mottled
