n. Cantharidus n., Adams Zool. Proc, 1851, p. 169. About the size of E. 

 bellulus, with a produced aperture, the enamel minutely dotted in slopmg 

 lines, last whorl angular, throat brilliant green. Long. 18, lat. 13, whorls 

 7. One of the commonest species. 



Bankivia vakians. Beck in Krauss Sudafric. Moll , 1848. " This 

 species" says Mr. Angas (Zool. Proc, 1865, p. 181) "is very abundant on 

 all shores of extra-tropical Australia. It varies in color from green to white 

 brown, purple and rose, besides being banded and striped in an infinity of 

 patterns." H. and A. Adams describe (Gen. Moll, p. 425) another species 

 B. major, as Tasmanian. I have been unable to find the shell. Some 

 authors give the name inirpurascens after Deshayes (Manuel de Conch). 

 It was supposed to occur also in S. Africa (Phil Handh. Conch, p. 212) but 

 this arose, as I have already noted, from Baron Von"* Ludwig sending to 

 Stuttgart, Australian with African shells. It has, however, been found in 

 America. One very young specimen teste Carpenter, Brit. Mus. Cat. 

 Maz. Shells, p. 226. The affinities of this singular shell are very doubtful. 

 Woodward (Manual Moll, p. 144) says it would be called Chemniizia (?) if 

 fossilized. Very common. 



GiBBULA multicakinata. Tenisou- Woods. 



GiBBULA coxi. Angas, Zool Proc, 1867, p. 115, pl^ 13, iig. 26 

 Orbicularly conical, deeply umbilicated, soHd, whitish, shining, marbled 

 olive and pink, whorls biangular, with two prominent rounded keels. Kare, 

 and S.E.A. About 8 mil. in diam. Varies much in coloring. 



GiBBULA SULCOSA. A. Adams, Zool. Proc, 1851, p. 186. Rare. A 

 small conical shell about 8 mill, high, umbilicate, sulcate, and faintly 

 obliquely striate, spotted with rosy lines and dots. It is fovmd as far north 

 as the tropics of Australia.

Trochocochlea austbalis. Favanne, Conch., pi 8, fig. Al (le ratelier). 

 There is such confusion about this shell that I shall give what I believe to 

 be its synonomy. Chemnitz Conch, tom. 11, tab. 196, fig. 1890. Monodonta 

 australis, Lamarck ani., s. vert. tome. 7, p. 30, No. 11. T. concamerata. 

 Gray and Wood Ind. Test. Sup. pi. 6, fig. 35. T. striolatus, Quoy and 

 Gaim., Zool. de I'Astrol, Vol. 3, p. 253. T. striolatus, Angas, P.Z.S., 1865, 

 p. 182, No. 170. Encyclop. Methodique His. Nat. des Vers., T. australis. 

 Mr. F. G. Angas says in his notice of the shell (loc. cit.), " Faintly edged, 

 and painted with irregular wavy longitudinal lines of yellow on a black 

 ground. L. (sic. perhaps a misprint for T.) striolatus of Quoy from 

 Tasmania and S. Australia is much more depressed and has a tesselated 

 style of painting, althoTigh regarded as a synonym by Mr. Hanley in his 

 edition of Wood's Index." I think Mr. Angas would alter his opinion in 

 Tasmania where every variety of form and every variety of color from pale 

 yeUow to green, and from white to black, and every variety of tesselation 

 may be found on the same beach. 



Trochocochlea constbicta. Lamar ch, Vol. 9, p. 180. The largest 

 species, obUque, obtuse, conical, dull flesh color, or sordid white, or yellowish, 

 often a reddish pink ; whorls 4-5, tumidly convex, furnished with rounded 

 very conspicuous keels, 8 on body whorls, 2 on the others, the whole shell 

 traversed with oblique fine Hues of growth ; mouth subcircular ; outer lip 

 double, outer margin calcareous pinkish white, channelled at the origin of 

 the keels, where it is often stained deep black which sometimes continues 

 in a Une round the mouth ; mouth nacreous, in a well-defined line, with 

 prominent lirse ; nacre silvery, columella purely white, terminating in a blunt 

 tubercle ; enamel spread sHghtly over base, on which 3 or 4 ribs are often
