COMINELLA LACTEA. Rccve, Icon., Buccinum, fig. 117. This certainly 

 appears to be no more than a greenish white variety of the last very variable 

 shell, as also C. quoyana, A. Adams, Zool. Proc, 1854, p. 313. It occurs in 

 New Zealand. 



COMINELLA TASMANICA, Tenisoil-Woods. 



CoMiNELLA cosTATA. Q,uoy. Voy. Astrol., Vol. 2, p. 417. Very variable in 

 color but generally of a reddish brown hue, spu-e acute and nodose ; about 

 the same dimensions as C. alveolata. B. Sts. ; common. Kare on S. Coast. 



CoMiNELLA ANGASi. Cvosse. Joum. dc Conch., 1864, p. 275. I cannot 

 regard this as more than a dark variety of the preceding, as also C. 

 Adelaidensis (Crosse loc. cit.J which, however, is not foimd in Tasmania. 



Ada^isia typica. Dunlcer, Zool. Pro., 1860, p. 421. This generic name 

 may have to be changed as it is pre-occupied by one of Prof. E. Forbes' 

 genera of Heliantlioid anthozoa with tubular retractile tentacles. Is the 

 genus a good one ? Mr. Angas says that the operculum is purpuroid. As 

 we have a DunTceria in conchology we cannot re-name it after the founder. 

 I propose if the genus is to be maintained that it be called Agneivia, after 

 the distinguished Secretary of the Society to which Tasmanian science is so 

 largely indebted. A coarsely ribbed conspicuously Urate shell like a Comi- 

 nella, but with a pui-puroid operculum. The Tasmanian species are banded 

 with purple or chestnut. Rare, N ; in S.A., and S.E.A. Long. 32, lat. 17. 



Nassa fasciata. Lam. Vol. 10, j). 169. Our largest Australian species, 

 and probably the most common (except in Tasmania) in all extra tropical 

 Austraha. Very ornamental with ribs and granulation, besides being very 

 prettily banded with lines varying in different specimens from brown to 

 light yellow. The coloring of the whole genus is extremely variable, and 

 must not be regarded as of specific importance. Long. 18, lat. 11. 



Nassa pauperata, Lamarck, Vol. 10, p. 183. Common, and found 

 widely distributed like the preceding. It is smaller, more squat and sordid 

 in appearance. Generally darker in color, but sometimes even white or 

 covered with a greenish periostraca. Long. 18, lat. 13. 



Nassa rufocincta. A. Adams., Zool. Proc, 1851, p. 106. A very small 

 aubturretted chesnut banded species with 11 to 13 ribs on the last whorl. 

 Long. 10 ; rare. B. Sts., S.E.A. (Pig Island, Tamar ; R. M. Johnston.) 



Nassa jacksoniana. Kiener, Mon. Bucc, pi. 19,/. 73. Not uncommon. 

 A white, thin, poor shell, smaller than N. pauperata ; often found almost 

 transparent. S.E.A. Long. 12, lat. 10. 



Nassa tasmanica. Tenison-Woods. 



Purpura textilosa. Lamar cl, Vol. 10, p. 71. A coarse whitish shell* 

 coarsely granulated and transversely ribbed, which the French naturalist 

 somewhat fancifully compared to canvas ; about 50 to 60 long by 37 to 42 

 wide ; very common in all extra-tropical Australia. 



Purpura husiilis. Crosse, Joum. Conch, 1865, jj. 51. Common in S. A. 

 A small yellowish shell with equidistant red nodules. Long. 10., lat. 7. 



Purpura succincta. Martijn Univers., ConcJi., 2 Vol. pi. 45. Deeply 

 sulcate and without granules. A doubtfully distinct species from P. textilosa, 

 the gradations from one form to the other being readily found. The Tas- 

 manian specimens are inteimediate between P. textilosa and the extreme 

 form of P. succincta as found in N.S. Wales and New Zealand. Reeve, perhaps 

 on the authority of Krauss ( Sudafricanische Mollushen p. 118), quotes this 

 shell as being found at the Cape of Good Hope. Dr. E. Von. Martens, 

 however, states that in the South African shells examined by Krauss, sent 

 to the Museum of Stuttgart by Baron Von Ludwig, there were a good many 

 Australian species, and that Krauss was not aware of this.
