XV. RECENT MOLLUSCA. 
The Shells in this Collection ave arranged according 
to the system of classification adopted in ‘ Woodward's 
Manual,” —(Weale’s Series, 1866, price 5s. 6d.) 
The Mollusca of the New Zealand coasts belong to 
the Australo-Zelandic Province, which includes New 
Zealand, the Chatham Islands, Tasmania, and Extra- 
tropical Australia from Sandy Cape on the east, to the 
Swan River. 
In the Collection, several of the species found in 
the other sub-divisions of the aboye province, but not 
in New Zealand, lave been placed for comparison, 
but they are distinguished by the colouring of the 
mounting, and in the Catalogue thus (x). 
A blank space opposite the name of a Shell men- 
tioned in published lists, indicates the fact that it is 
not as yet represented in the Collection ; and where 
the species is of doubtful occurrence in New Zealand, — 
an asterisk is prefixed, as in Dr. Gray’s List of New 
Zealand Shells, given in Vol. IL of “ Dieffenbach’s 
New Zealand,”—Murray. 1843. 
The specific names have heen determined by 
reference to that work, as well as to those mentioned 
in the following list, and where the species has not 
been recognized it is merely distinguished by a letter :—
