54 DR. J. C. COX ON NEW AUSTRALIAN LAND SHELLS. [Jan. 17, 



A fine showy species combining the characters of Helix macleayi 

 and Helix blomfieldi, and found, in company with the former, rather 

 abundantly. 



2. Helix coxeni, sp. nov. (Plate III. figs. 2, 2 a.) 



Shell deeply, rather largely, and openly umbilicated, depressedly 

 globose, very thin, translucent, light yellow-brown, irregularly striated 

 with slightly raised waved striae, irregularly studded with numerous 

 sharp, rather long, fine recurved bristles ; whorls 5^, last rapidly 

 increasing in size, a little descending in front, and considerably in- 

 flated ; aperture broadly oval, anterior margin scarcely everted, 

 posterior broadly everted ; columella much dilated, slightly covering 

 the umbilicus, and produced beyond it ; margins joined by a thin 

 callus. 



Diameter, greatest % 97, least O/O ; height 063 of an inch. 



Hab. Whitsunday Island, off Port Denison, Queensland. 



I have named this species after Mr. Coxen of Brisbane, an ardent 

 and enthusiastic collector of our Australian shells. 



3. VlTRINA SUPEREA, Sp. 110V. 



Shell depressed, orbicularly auriform, light olive-green, rather 

 opaque, shining ; whorls 3, convex, rapidly increasing, last much 

 expanded ; spire scarcely raised, rounded, striated with lines of 

 growth ; aperture oblique, lunar-ovate, largely open ; peristome 

 simple, thin ; columella sharply arched ; margins widely separated. 



Diameter, greatest 1*20, least (V/4 ; height 0"59 of an inch. 



Hab. Mount Dryander, Port Denison, Queensland. 



This fine species is, so far, the largest known. According to Reeve's 

 figure it must closely resemble Vitrina magnified, but is larger and 

 more depressed. 



4. Helix bellengerensis, sp. nov. 



Shell deeply, rather narrowly umbilicated, turbinately depressed, 

 lenticular, thin, dark claret-brown, not shining; whorls 5 \, coarsely 

 obliquely striated, very gradually increasing in size, last whorl rather 

 sharply keeled at the periphery and depressed in front ; base convex ; 

 aperture rotundately lunar ; last whorl suddenly contracted behind 

 an everted peristome, which is white and slightly thickened ; mar- 

 gins approaching ; anterior margin inserted below the carina ; colu- 

 mellar margin only slightly dilated. 



Hab. Bellenger River, east coast of New South Wales. 



Diameter, greatest 0-55, least 0-48 ; height 0*35 of an inch. 



A simply lenticular species allied to H. leucocheilus, Cox, from 

 which it differs in being more conical and more sharply keeled. 



5. Helix sarda-labiata, sp. nov. (Plate III. figs. 3, 3 a.) 

 Shell deeply, openly, rather largely umbilicated, orbicularly conoid, 



thin, smooth, very finely striated throughout, pale fawn-grey ; 



whorls 6, gradually increasing in size, the last sharply deflected" in. 



front ; aperture oval, margins closely approximating, slightly thick-
