Class Cephalapoda. 



Argonauta oryzata. Meush. Miis. Gev. 252, 133. This well-known 

 shell, the " Paper Nautilus " of collectors is rarely found in Tasmania. Two 

 species are found in E.A., not uncommon in S.A. 



Spirula l^vis. Graij, Cat. Moll. Brit. Mus. Pt. 1, it. 116. S.A., E.A., and 

 W.A., rather uncommon. 



Sepia. Two species at least, not determined, and others of Octopus, 

 Cistopus, Onychoteuthis, etc. 



Class Gasteropoda. 

 MuREx TRiFORMis. Reeve, Icon. 2^1. '^^,Ji!J- 53. Somewhat common but 

 generally worn and imperfect specimens only. The shell seems as if its 

 growth were stunted by its southern habitat, while in South AustraKa the 

 varices expand into beautiful and delicate frills. 



MuREX ZONATUS. Tetitson- Woods. 



Murex angasi. Crosse, Jour, de Conch. 1863, p. 86, pi. 1, fig. 2. Two 

 small specimens of this rare shell have been shown to me from the W. Coast. 

 It has three varices which are canaliculately hooked at the upper part. 

 There are three tubercles between each varix on the upper part of the whorl. 

 One is strongly inclined to regard this as allied to M. acanthopterus, M. 

 pinniger, M. phyllopterus, and M. falcatus. Common in the dredge at Long 

 Bay. W. F. Petterd. 



Typhis arcuatus. Hinds. Voy. Sulphur, vide Descr. Novce. spec. ah. aue. 

 Reg. Soc. Tas. Proc, 1876. 



Trophon umbilicatus. Ten ison- Woods. In this and all succeeding 

 references to the author's name, the species will be found described in the 

 Society's Proceedings for 1875 and 1876, and the names in this list are 

 printed thus for the piu-pose of labelKug collections. 



Trophon Petterdi. Crosse Jour. Conch., 1864, pi. 5, fig. 20. Abundant- 

 A yellowish white or brown cancellated shell. Long. 21, lat. 11. Whorls 6* 

 Generally distributed. 



Trophon br.izieri. Tenison- Woods. 



Trophon assisi. Tenison- Woods. 



Trophon goldsteini. Tenison-Woods. 



Trophon mari^. Tenison- Woods. 



Trophon hanleyi. Angas. Zool. Proc, 1867, p. 110. This New South 

 Wales shell is said to occur in Tasmania, but I have seen no specimen.
