Jaffa, 2 poor : in 150 fathoms off Beachport, 1 poor. It is 

 •evidently alive in water up to 55 fathoms. 



The protoconch is prominent, consisting of three well- 

 rounded whorls, of which the first two are smooth, the third 

 gradually develops four spirals of tiny tubercles. It ends 

 ^abruptly, and then the very bold axial costate sculpture of the 

 spire-whorls begins. The protoconch may be wholly light- 

 brown or only its third whorl.

Vanikoro denselaminata, Verco, Trans. Roy. Soc, South Aus- 

 tralia, 1909, vol. xxxiii., p. 334, pi. xxix., figs. 1, 2, and 3. Mr. 

 Gatliff has suggested that this is the juvenile state of V. vin- 

 centiana, Angas, as may also be gathered from Tate and May's 

 note, and this is confirmed by my examination of a series of 

 Angas' s species; so I place my name as a synonym and add the 

 following observations: — Some examples show spirals in the 

 whorl immediately following the protoconch, in others these are 

 obsolete. In the later portions of the adult shell, the axials 

 become obsolete, and crowded spirals may become quite valid. 



Taken on the beach at Reevesby Island, Spencer Gulf, 

 and St. Francis Island. Dredged in Backstairs Passage and 

 Gulf St. Vincent, depth unrecorded. It appears to be a com- 

 paratively shallow water form, not having been taken by me 

 at any greater depth than 22 fathoms.
