As there is great difference among conchologists in the spelling of the 

 specific name intended to represent that the species comes from New Zea- 

 land, I shall spell it uniformly neozelanicus, as I have already done in my 

 Eevision of the Land Shells, believing that this is the most correct and the 

 shortest form.

Dentition, 1-1-1, or 0-1-0. 



Sub-order Hamiglossa.

Varices with five or six slightly curved spines on each whorl, the pos- 

 terior much longer than the others.
