1-18 DR. J. C. COX ON NEW LAND-SHELLS FROM [Jan. 21, 



Diam., greatest 076, least 0"C4 ; height 0*92 of an inch. 



Hah. Solomon Islands. 



In the collection of Mr. W. H. Hargraves, of Sydney. 



This species is closely allied to H. adonis of Angas ; hut after 

 comparing it with a number of specimens of that species I feel sure 

 that it has permanent differences ; it is a much thinner and lighter 

 shell, much more sharply keeled, and much less coarsely sculptured. 



Helix mendan^e, sp. nov. 



Shell with a deep, broad, open perspective umbilicus, discoid, 

 white, semiopaque, smooth and shining, finely transversely striated 

 throughout with lines of growth, ornamented with two narrow dark 

 brown bands, one immediately above, the other immediately helow 

 the periphery of the last whorl, and continuous to the apex of the 

 spire ; the last whorl is subcarinated only for a short distance near 

 the insertion of the outer margin of the aperture ; spire convexly 

 flattened ; whorls 6, gradually increasing in diameter, the last not 

 depressed ; base convex ; aperture oblique, irregularly subcircular ; 

 margins approximating, joined by a thin brown callus ; lip slightly 

 thickened and everted. 



Diam., greatest 0*72, least 0'63 ; height - 35 of an inch. 



Hah. Solomon Islands. 



In my own collection. 



A semiopaque, white, flattened species, with a conspicuously 

 open umbilicus, and ornamented with two narrow dark brown bands, 

 one above, the other below the periphery of the last whorl. 



Helix (Cam^ena) barneyi, sp. nov. (Plate XVI. fig. 2.) 



Shell with a deep open umbilicus, orbicularly conoid, obliquely 

 finely concentrically striated, of a brown-yellow colour, shining, 

 having a broad chestnut band below the suture, and a second 

 narrower band below the subcarinated periphery with an undefined 

 lower margin ; spire bluntly convex ; whorls 7, convex, the last 

 considerably deflected for about T 6 lT of an inch in front ; peristome 

 simple, straight ; lip everted, margins approximating, joined by a 

 dark-coloured callus ; columella irregularly dilated and broadly 

 reflected, half covering the umbilicus ; margin of the aperture black 

 within. 



Diam., greatest T30, least 1*10 ; height 1*15 inch. 



Hab. Barney Island, near New Guinea, Torres Straits. 



In my own collection. 



Helix howinsul*, sp. nov. 



Shell very narrowly but openly umbilicated, lenticular, thin, dark 

 brown ; spire flatly conoid ; suture margined ; whorls 6, above 

 standing flatly outwards, very coarsely striated with prominent folds 

 of a thick brown horny epidermis, which terminate at the periphery 

 in a prominent fringe, below corneous, smooth, shining, having there 

 no promiuent folds of epidermis ; last whorl not descending in front, 

 sharply keeled ; suture narrow and deep, margined with a prominent
