1. Siphonaria diemenensis, Quoy and Gaimard.

(= denticulata, Q. and G., 1833 = scabra, Reeve, 1856). 



Specimens from the Kermadec Islands are in my collection. 

 They differ but shghtly from Tasmanian examples, an opinion 

 also shared by Mr. C. Hedley, of Sydney, to whom I sent the 

 shells for examination. 



Both species of Quoy and Gaimard are enumerated in Cap- 

 tain Hutton's Catalogue, 1873, but our large S. oUiquata, Sow., 

 was taken for diemenensis, and S. zelandica, Q. and G., for den- 

 ticulata. In his " Revision des Coquilles de la Nouvelle Zelande 

 et des lies Chatham," 1878, S. diemenensis (= denticulata, 

 C.M.M.) is again on the list, with the remark, " II existe, au 

 Museum colonial, des exemplaires de cette espece, mais la localite 

 est douteuse." In the Manual, 1880, the species diemenensis 

 and denticulata are omitted, and the same is the case in Hutton's 

 article on the New Zealand Siphonariidiv.* 



2. Bulla adamsi, Menke. 

 Having a few specimens of a (to me) unknown Bulla, ob- 

 tained at Cape Maria van Diemen, and no literature for naming 

 them at my disposal, I availed myself again of Mr. Hedley's 

 never-failing kind help, and the specimens were returnpd with 

 the name " (1) B. adamsi, Mke." To make quite sure about 

 the species I sent examples to Mr. E. A. Smith, of the British 

 Museum, and with his usual courtesy he informed me that he 

 considered them as small examples of B. adamsi, which may 

 only be a form of B. ampulla, L., judging from the shells. 



3. Mitromorpha striata, Hutton, sp. 

 Bela striata, Hutton, Cat. Tert. Moll. N.Z., 1873, p. 5. Daph- 



nella striata, Hutton, Proo. Linn. Soc. N.S.W., 1886 (1887), 



p. 214 ; Pliocene Moll. N.Z., in Macloav Meni. Vol., 1893, 



p. 52, pi. 7, fig. 33. 



One specimen was dredged by Captain J. BoUons in 37 

 fathoms off Cuvier Island, and kindly presented to me. It
