I have found this species not uncommon in shell-sand from 

 Lyall Bay, near Wellington ; Titahi Bay shell-sand also showed 

 it ; whilst I have one specimen from seaweed-washings from 

 Taylor's Mistake Bay, near Sumner. It is a very fragile shell, 

 and the majority of the specimens noted are imperfect. Having 

 carefully compared specimens, there is no doubt it is congeneric 

 with Cyclostrema angeli, Ten. -Woods, and for the present the 

 best location is in the genus Cyclostrema. 



Rissoa emarginata, Hutton.

Vol., 1893, p. 65, pi. viii, fig. 68. 



This peculiar little shell is an addition to the list of Pliocene 

 fossils found recently. I have found it in shell-sand from Purau, 

 Lyttelton Harbour ; in shell-sand from Lyall Bay, near Wel- 

 lington ; and Queen Charlotte Sound, 30 fathoms. From the 

 description and figure, the shell recently described as Rissoina 

 parvilirata, Suter (Trans. N.Z. Inst., vol. xxxix, p. 257, pi. ix, 

 fig. 5, 1906 [1907J ) would appear to be its nearest ally, if not 

 identical. 



Cominella costata (Quoy and Gaimard). 



Buccinum costatum, Quoy and Gaimard, Voy. " Astrolabe," 

 Zool, vol. ii, p. 417, pi. xxx, figs. 17-20 (1833). 



This species has only recently been re-recorded from 

 New Zealand ; locality unknown : Suter, Trans. N.Z. Inst., 

 vol. xxxviii, p. 330, 1905 (1906). Collecting at Shag Point, 

 Otago, I found a dead specimen of this shell. 



Siphonalia valedicta (Watson). 

 Fusus valedictus, Watson, Rep. Scient. Results " Challenger," 

 Zool., vol. xv, p. 201, pi. xvii, fig. 7, 1886. Siphonalia 

 mandarina, Duclos, var. valedicta, Watson, Index Fauna? 

 N.Z., p. 72, 1904. 



The type specimen was dredged in 275 fathoms, 200 miles 

 west of Cape Farewell, New Zealand. I do not know whether 

 it has been since found. If it has not, the finding of a dead shell 

 on the south coast of Otago Peninsula must be of interest. My 

 specimen has the apical whorls missing, and the outer lip is 

 broken. Having collected numbers of S. mandarina, Duclos, 

 in'all stages of growth, it appears to me that this shell is worthy 

 of full specific rank, as Watson gave it.
