cae 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.

By T. W. Kmer, Assistant in the Colonial Museum. 
[Read before the Wellington Philosophical Society, 21st February, 1880.] 
Ur tothe 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 polished, and really beautiful species. 
Vitrina milligani, 
Shell pbi noni rather solid, polished, very glossy, translucent, 
olive-blaek ; spire convex; whorls three, second convex, last depressly- 
rounded; aperture more oblique than diagonal, lunately rounded-oval, 
within coloured as without; peristome simple; right margin dilated for- 
wards, anterior regularly and columellar slightly arched. (Petterd).
