elongate, turretted, numerous spiral keels, sordid brown. Long. 8, lat. 2, 

 whorls 7 to 8. Common. S. 



Cerithiopsis atktnsoni. Var., Tenison-Woods. Perhaps no more than a 

 variety of Cerithiopsis crocea, Angas, Zool., Proc, 1872. It is not, however, 

 orange in color, and it is a narrower shell. Long Bay, dredged from sand at 

 10 fathoms by Kev. H. D. Atkinson. Rare. 



Cerithiopsis albosutura. Tenison- Woods. . 



Triforis tasmanica. Tenison- Woods, var. a. 



TuRRiTELLA TASMANICA. Reeve, Icon., pi 9, fig. 42. An accuminated 

 eheU with flattened whorls and two or three inconspicuous keels, forming a 

 raised area to the centre of the whorl. Long. 45, lat. 10, whorls 16. 

 Common, and in S.A. 



TURRITELLA GRANULIPERA. TenisoU-Woods. 



TuRRiTELLA TASMANiENSis. Tenison- Woods. 



TuRRiTELLA ACUTA. Tenisou- Woods. 



TuRRiTELLA siNUATA. Eecvc, lol. 11, fig. 62. Two keels, and deeply but 

 broadly sinuate at the mouth ; fleshy brown. Long. 21, lat. 7, whorls 14. 

 Common. 



Vermetus dentiferus. Lamarck, Vol. 9, p. 65. Common in B. Sts. 

 Our only species and therefore easily distinguished. 



Tenagodus australis. Quoy, Voy. deVAstrol., Vol. 3, p. Z02. This is 

 what is generally known as the large Siliquaria of our coasts, with a line of 

 round dotted perforations along the sHt. Common. N. Good specimens 

 65 mil. with 4 to 5 convolutions. 



Tenagodus weldh. Tenison- Woods. 



Dentalium tasmaniensis. Tenison- Woods. 



Dentalium weldiana. Tenison- Woods. 



Littorina unipasciata. Gray, King's Voyage in Australia, Appendix^ 

 Vol. 2. Ovately conical, white or blmsh white, whorls sub-convex, last sub- 

 angular, throat brown-purple with anterior white spiral bands, spire acute. 

 Long. 26, lat. 12. Common, and in all extra-tropical Australia. 



Littorina paludinella. Reeve, Icon., pi. 16, Ug. 84. Minute, dark 

 olive, horny, apex acute, aperture dilated. Diam. 1 to 5 mil. Common. 



Littorina hisseyana. Tenison- Woods. 



Littorina undulata. Gray in King's Voy. loc. cit. Like L. unifasciata 

 but more globose and with zigzag lines. Probably only a variety, for in a 

 good series of specimens every gradation of one form to the other can be 

 traced. A carefid investigation of large collections of Littorinas would, in 

 my opinion reduce the number of species considerably. 



Littorina philippi. Carpenter, Cat. Maz. Shells, p. 349. Is said to occur 

 in Tasmania as well as S. Austraha, but I beUeve the identification in both 

 cases to be very doubtful. 



EiSELLA NANA. LamarcTc, Vol. 9, p. 150. A small, corroded, sharply 

 angulated shell with zebra-like markings. Very common and in V. This 

 ehell is the female of the two following. See Proc. Lin. Soc, N.S. W., 1876. 



RiSELLA aurata. H. and A. Adams, Gen. Moll, pi. ZS, fig. 5. A yellow 

 mouthed acutely angled species, nodular at the suture and larger than the last. 

 Common on N. Coast, and in S.A. Long. 24, lat. 18. I qmte agree with 

 Mr. Angas in regarding this as only a variety of the following. 



RiSELLA MELANOSTOMA. GmcUn, p. 3581, No. 90. The black mouth and 

 lugubrious habit may distinguish this shell which is near in form to 

 the preceding. This or the R. aurata is figured in Woodward's Manual as 

 B, nanaf pi. 9, fig. 14. Common. Gmehn states that this shell has a deep
