mstructus and E. atratus. E. scabriusculus is very similar to both these 

 but smaller. S.E.A. 



Thalotia conica. Gray, in King's Voy., Append., Vol. 2, p. 479. A 

 Bolid conical shell, light red, with finely granular lines, regularly spotted 

 purple red. Long. 20, lat. 13. Common. B. Sts., and N.E. only, but very 

 common in S.A. 



Thalotia picta. Wood's Index Testaceologicus, Suppl., pi. 6, jig. 28. 

 More acute than the preceding, with very fine lirse, and elegantly flamed 

 with carmine and white. 1 . ramburi, Crosse (S.A.), may be only a variety 

 of this. Eare. N. only. 



Thalotia marine. Tenison- Woods, Proc, Roy. Sac. Vict., 1877. Common 

 in Victoria. Kare in Tasmania and N. only. 



Thalotia dolorosa. Tenison- Woods. 



ZiZYPHiNUS ALLPORTI. Tenison-Woods. 



ZlZTPHINUS LEGRANDI. TcnisOU- Woods. 



ZizYPHiNus GRANULATus. Bom. Tcst. Miis. Cces. Vind., p. 337,^?. 12. 

 A British species said to occur in Tasmania, but if my identification of the 

 shell is correct, it is only a variety of Z. armillatus, diS'ering from age. 



ZiZYPHiNUS EUGLYPTUS. Adams, Zool. Proc, 1854, p. 68. This, at best, 

 is only a variety of the following. 



ZizYPHiNus ARMILLATUS. Wood, Indcx Test. Suppt., .pi. 9, fig. 5. Of 

 pinkish red colour, transversely grooved and granulate ; apex often with a 

 beautiful bluish green metallic lustre. A fine large, conical shell, varying 

 considerably in size and depth of color. Large specimens long. 33, lat. 

 32, whorls 8. Kather common and S.A. 



ZiZYPHiNUS FRAGUM. PJiilippi, Zeit. Mai, p. 106. Shell conical, dull 

 white, faintly tesselated with brown, whorls convexly sloping and spirally 

 closely granular. Its name is not inaptly suggested by its resemblance to a 

 strawberry. Alt. 10, diam. 13, whorls 6. Kare. Islands in B. Sts. 



ZiZYPHiNUS EsrcERTUs. Peeve, Icon., pi. 5, Jig. 28. This is a reversed 

 shell, which was thought by Reeve to be an accidental variety. It is, how- 

 ever, always found thus. This fact and the somewhat convex base show 

 anatomic peculiarities which ought to be of generic value. 



Elenchus RADIUS. Wood, Index, Test, Sicpjx, pi. 6, fig. 46. A very 

 common, smooth, brown shell, common in all S. Australia, This shell, the 

 largest of the genus, with many synonyms, is the one principally used for 

 ornamental piirposes ; the outer shell is dissolved by weak acid, exposing the 

 brilliant violet nacre. Swainson named it splendkluhis, from its great 

 beauty. Long. 30, lat. 15, whorls 6. ElencJius fidmineus, Kiener, is a 

 variety distantly banded with diagonal zigzag greenish white lines. Elenchus 

 Uneatus, Lamarck, Vol. 9, p. 181, is another variety, very closely 

 variegated with diagonal lines. Elenchus roseits, Lamarck, loc. cit., is a 

 rose red variety. But none of these distinctions are of specific value, for 

 almost every intermediate gi-ade can be found in a handful of specimens. 



Elenchus bellulus. Dunher, Phil. Ahhild., t. 7, fig. 6. A highly 

 enamelled tumid solid shell, brown, with transverse lines, which are 

 curiously connected with double short white lines, shaded with vermilion. 

 These lines extend in fascia round the spii-e. Long. 17, lat. 10, whorls 6. 

 Uncommon. B. Sts. only and in S.A. 



Elenchus irisodontes. Quoy., Voy. de VAst^-ol, Vol. Ill, p. 246, t. 63, 

 figs. 7 to 12. Monodonta virgata, Menhe. Much smaller than E. badius, 

 beautifully variegated with bands and lines of various shades of green and 

 white ; nacre apple green. Used also for ornamental purposes. Long. 12, 

 lat. 7, whorls 5, Common. 



Elenchus nitidulus. Phil. Kust. Conch. Cat., pi. iZ,fig. 10, aa Trochu*
