posterior tooth, and a minute prong-like tooth immediately 

 beneath the umbo. 



Height, 2; width, 2.4 mill. PI. VII., figs. 2, 2a. 



Hab. — Surprise Bay, King Island, in shell sand, six 

 single valves. 



In size, and to some extent outline, this resembles .1/. 

 gemmrttu, Tate, from South Australia, but that species is 

 ornamented with divaricating sculpture, and is still more 

 inequilateral. Shells of this genus are usually strongly 

 sculptured; the present species is therefore remarkable for 

 its perfect smoothness. 



Natica kiiir/ensis, Sp. nov. 



Shell very small, ovately turbinate with a small spire, 

 perforate. Colour light yellowish chestnut, a darker band 

 immediately below the suture, and a broader light band be- 

 low that; there is a patch of deeper colour behind the umbi- 

 licus, which is rather small, narrow, and deep. Whorls 

 four, rapidly increasing, the body whorl large. Aperture 

 semi-lunar, sharply pointed above. 



Height, 2.5; diameter, 2 mill. PI. VII., figs 3, 3a. 



Hab. — Plentiful in shell sand at Currie Harbour, King 

 Island, where about 200 specimens were collected, which are 

 of very uniform size. 



I place this little shell in Natica, as its general char- 

 acteristics seem to point to that genus, but this may 7iot be 

 its final location. 



A}(jaliiita kinr/oisis, Sp. nov. 



Shell small turbinate, solid, dull white, with faint 

 brown rays, perforate. Whorls four, rapidly increasing; 

 spire not much elevated. The upper surface is faintly 

 spirally Urate; under surface smooth. Aperture roundly 

 pyriform, the columella lip somewhat expanded, behind which 

 is an ample umbilicus. 



Major diameter, 2.5; height, 1.8 mill. PI. VII., figs. 5, 

 5a, 5b. 



Hab. — Typo with three others from Surprise Bay, King 

 Island, in shell sajid. .\il the specimens arc rather beach 

 worn. 



This is close to A. fhictiiuta, Hutton, from New Zea- 

 land, which differs principally in its smaller umbilicus and
