Terrestrial Mollusca from Norfolk Island. 527 



Advena campbellu nepeanensis, subsp. n. 



Shell much broader and with less elevated spire than has 

 A. campbellu (Gray) * from Norfolk and Phillip Islands. 

 Alt. 15, diam. maj. 27, diam. min. 23'5 mm. 

 Hab. Nepean Island, in subfossil condition only (R. Bell). 



Fanulum testudo, sp. n. 



Shell roundedly turbinate, with strongly earinate periphery 

 and very slightly convex base, yellowish, irregularly trans- 

 versely banded and mottled with reddish chestnut above, 

 the transverse banding becoming paler and less marked on 

 the base of the shell; whorls 5, regularly increasing, marked 

 only with transverse ridges, which assume a more definitely 

 sculptural appearance on the latter half of the last whorl; 

 suture very lightly incised, narrowly, but coarsely callously 

 margined above; columella margin white, obliquely de- 

 scending, bearing an oblique, oblong, tooth-like projection 

 above; labium simple, acute, receding below ; aperture sub- 

 rectangular; interior of shell showing the reddish-chestnut 

 markings through the test. 



Alt. 4 - 5, diam. maj. 7*75, diam. min. 7 mm. 



Aperture: alt. 2'5, diam. 3 mm. 



Bab. Mount Pitt, Norfolk Island (R. Bell). 



QuiNTALlA, gen. nov. (Zonitidce). 



Shell imperforate, turbinately conic, minutely spirally 

 striate, angled at the periphery. 



Genotype : Caracolla stoddarti, Gray f, from Phillip 

 Island. 



Hob. Norfolk Island and immediately adjacent islets. 



The above genus includes, besides the type-species, Helix 

 flosculus, Cox J, and the subspecies below described, which 

 would seem to be intermediate between C. stoddarti and. 

 H. flosculus, both of which have been erroneously placed in 

 the New-Zealand genus Carthcea, the former by Sykes §, the 

 latter by Pilsbry ||.
