1871.] DR. J. COX ON NEW LAND-SHELLS. 645 



Hab. North end of Expedition Range, Rockhampton, Queensland, 

 Australia {Anderson). 



This species in its general aspect closely resembles Helix yulei, 

 Pfr. ; but from many fine specimens collected by Mr. Anderson I 

 find it unvarying in its characters, of which the occluded umbilicus 

 is most conspicuous. 



Helix scandens, sp. nov. (Plate LII. fig. 5.) 



Shell narrowly umbilicated, turbinately globose, of a dull reddish- 

 yellow colour, thin, transparent, above finely striated throughout, 

 smoother below and shining ; whorls 5|, gradually increasing in size, 

 convex, last not keeled ; aperture broadly lunate ; peristome simple, 

 thin, columellar margin white and opaque, triangularly dilated over 

 the umbilicus. 



Diam., greatest 013, least 0*11; height O0!) of an inch. 



Hab. Port Macquarie, east coast of Australia, 6 feet from the 

 ground on the trunk of a tree. 



Helix kempseyensis, sp. nov. (Plate LII. fig. 6.) 



Shell very minute, perforate, globosely conical, thin, pale horny 

 yellow, (microscopically) striated ; spire obtuse, conical ; whorls 5, 

 slightly convex ; aperture lunately oval ; peristome simple, thin, 

 margins approached, columellar margin slightly dilated and everted 

 over the narrow umbilicus. 



Diam., greatest 004, least 003 ; height 0"03 of an inch. 



Hab. East Kempsey, MacLeay River, east coast of Australia; 

 found under leaves on wet ground. 



Helix macquariensis, sp. nov. (Plate LII. fig. 7) 



Shell broadly, openly, and deeply umbilicated, flatly depressed, 

 thin, transparent, very shining, glossy, yellow, striated above with 

 rather irregular coarse lines of growth, below smoother and finely 

 spirally striated, faintly rayed with broad chestnut-coloured mark- 

 ings ; whorls 4g, rapidly increasing at the last, rather flat and mar- 

 gined at the suture; apex scarcely raised ; aperture almost round, 

 slightly lunate ; peristome blunt and darkened, margins closely ap- 

 proached, columellar margin not expanded. 



Diam., greatest # 14, least 0*11; height - 06 of an inch. 



Hab. Port Macquarie, east coast of Australia ; under leaves on 

 damp ground. 



Helix guadalcanarensis, sp. nov. (Plate LII. fig. 8.) 



Shell imperforate, trochiform, rather solid, finely obliquely ar- 

 cuately striated, pale yellow-brown, ornamented with broad or narrow 

 dark chestnut lines, sometimes almost absent ; spire turbinate ; 

 whorls 5|, slightly convex, the last rather inflated, not descending 

 in front ; aperture large, very oblique, irregularly lunately rounded, 

 inclining to be angled at the periphery of the body-whorl ; peristome 

 white, porcellaneous, broadly expanded, margined with black exter-
