 toater MoUusca. 



By Henry Sutek. 



[Bead before the Philosophi:al Institute of Canterbury, 1st November, 



1893.] 



Very important changes in the classification of our MoUusca 

 and valuation of species have taken place lately, and I think 

 a check-list will be acceptable to New Zealand scientists. I 

 give short references to descriptions and figures contained in 

 works which are supposed to be easily accessible in New Zea- 

 land, and, to abbreviate as much as possible, the ciphers only 

 are used for the following works : — 



(I.) " Transactions of the New Zealand Institute." 

 (II.) Hutton: "Manual of New Zealand MoUusca," 



1880. 

 (III.) " Proceedings of the Linnean Society of New South 



Wales." 

 (IV.) Tryon : "Manual of Conchology;" continued by 



H. A. Pilsbry. Second series.
