MOLLUSCAN FAUNA OF NORTHERN NEW ZEALAND 157 



herein, particularly the new species of Cratis, Pedicularia, Dimya, Epicodakia, Borniola, 

 Zeidora, Starkeyna and Coenaadum. 



Also the land molluscan fauna of this proposed new province has the following re- 

 stricted species: Placostyhis bollonsi, Suter; Placostylus hongii ambagiosus, Suter; 

 Rhytida duplicata, Suter ; Serpho matthewsi, Suter ; and Succinea archeyi, Powell. 



The name of the province is based upon the name of a northern Maori tribe, the 

 Aupouri, and is particularly appropriate, as these people originally dwelt on the northern- 

 most mainland until they were defeated in battle by the Ngapuhi people and forced to 

 flee to the Three Kings Islands.
