III. — Molluscan Fauna of Some Parts of the Province of 



Auckland. 



Some time ago Mr. Charles T. Musson, F.L.S., of Eich- 

 mond, New South Wales, sent me a large number of shells 

 collected by him in the Province of Auckland, at Ohaupo, in 

 conjunction with Dr. Eud. Haeusler, for naming ; and I think 

 it worth while to publish a list of the land-shells. The locali- 

 ties are the following, as given to me by Mr. Musson : 

 1. Heavy bush, Parua Bay, near Whaiigarei. 2. Wha- 

 ngarei Head, bush on steep hill-sides facing sea. 3. Hillyer's 

 Creek, near Auckland. 4. Mount Wellington lava-fields. 

 5. Ohaupo. 6. Domain, Auckland.
