1. Helix Dunni^, Gray, Ann. Nat. Hist. v. 317, 1841 ; Fau- 

 nula iV. .^. 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. Helix Greenwoodii. 



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 Greenicood. 



This species is very like Helix Danniis in size, colour and form, 

 but the outer whorl is rounded, and with some very peculiar oblique 

 ridges on the outer periphery ; the umbihcus 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.
