 tantly, transversely striated. 



Length, -6 inch ; breadth, -07 at anterior end, 



Waikanae. 

 Dentalium, sp. 



A broken shell, in the collection of Mr. Herbert, Wellington, would 

 appear to add a fifth species of Dentalium to our " List ;" but as only about 

 half the specimen remains, and that the apical portion, its identification is 

 somewhat difficult. 



The shell is white, ribbed, ribs equal, about nineteen in number. 



Island Bay, Wellington. 

 Scalaria ivelUngtonensis. 



Shell white, lustrous ; acuminate, imperforate ; whorls nine, rounded ; 

 varices numerous, thin, about seventeen on the body- whorl ; interstices 

 smooth ; aperture sub-rotund.

Art. XLI. — Notice of the Occurrence of Vitrina milligani in New Zealand. 

 By T. W. KiEK, Assistant in the Colonial Museum. 

 [Read before the Wellington Philosophical Society, 21st February, 1880.] 

 Up to the present time only two species of Vitrina have been recorded as 

 indigenous to New Zealand.* I have now to notice the discovery of a 

 third ; a large, highly pohshed, and really beautiful species. 

 Vitrina milligani, Pfr. 



Shell depressly-ovate, rather solid, polished, very glossy, translucent, 

 olive-black ; spire convex ; whorls three, second convex, last depressly- 

 rounded ; aperture more oblique than diagonal. Innately rounded-oval, 

 within coloured as without ; peristome simple ; right margin dilated for- 

 wards, anterior regularly and columellar slightly arched. (Petterd). 



Diameter, greatest, -9 inch ; least, '6 ; height, -4 ; aperture, '6 inch 

 long, '4 broad. — South Karori (T. W. K.)
