2. Limacip2z. 
1. Hexix Dunnia, Gray, Ann. Nat. Hist. v. 317, 1841; Fau- 
nula N. Z. 247. n. 143. Named in honour of Mrs. Dunn, a relative 
of Mr. Joshua Alder, from whom I received the first land-shell from 
New Zealand. 
2. Herix GreEnwooptl. 
Shell rather depressed, largely umbilicated, pale brown, thin, pel- 
lucid, rugose ; spire slightly raised, outer whorl rounded, with three 
or four rather oblique ridges directed towards the front; umbilicus 
very large, conical, wide, deep, the pillar side of the outer lip straight 
and high. 
Hab. Auckland, New Zealand; Major Greenwood. 
This species is very like Helix Dunni@ im size, colour and form, 
but the outer whorl is rounded, and with some very peculiar oblique 
ridges on the outer periphery ; the umbilicus is much larger; the 
pillar-lip, as high as the confines of the umbilicus, is straight, and 
not arched, as in that species. 
I have great pleasure in dedicating it to Major Greenwood, who has 
so kindly enabled me to add the above genus, and this and the follow- 
ing species, to the New Zealand Fauna.
