452 Mr. E. A. Smith on three new Species of Helix. 



around the umbilicus are opalescent white and devoid of the 

 oblique markings and bands. In the type the upper ter- 

 minations of the brownish, oblique, irregular stripes on the 

 body-whorl ai - e almost of a reddish tint, and form as it were 

 a series of spots at the suture. The variety is of a uniform 

 opalescent or greenish-white colour, variegated above with 

 the radiating, somewhat zigzag, opaque, deep cream-coloured 

 markings, which on the lower surface assume the form of 

 zones and irregular spots or blotches. In form this species 

 bears some resemblance to H. Tayloriana (Adams & Reeve). 



2. Helix (Papuina) ianthe. 



Testa depresse trochiformis, anguste rimata, ad peripheriam acute 

 carinata, omnino alba, striis incrementi obliquis tenuibus sculpta ; 

 anfractus 4, superiores convexiusculi, ultiraus supra et infra 

 carinam leviter concavus, antice haud descendens ; apertura 

 oblique subquadrata, ad carinam acuminata ; peristoma superne 

 leviter reflesum, inferne latius expansum, margine columellari 

 late dilatato, umbilicum fere obregente ; spira breviter conica, ad 

 apicem obtusa. 



Diam. maj. 25| millim., min. 21 ; alt. 13|. 



In form this species is very like H. hero, but more obtuse 

 at the apex, and the aperture is not quite so acuminate. It 

 differs also from that species in the absence of colour-markings 

 and spiral stride. The last whorl also is a trifle narrower and 

 does not descend in front. 



3. Helix (Papuina) cerope. 



TeBta sublate umbilicata, depresse trochiformis, ad peripheriam 

 obtuse angulata, pallide vel albido-fuscescens, circa medium zona 

 angusta rufa cincta ; anfractus 5, convexiusculi, sublente accres- 

 centes, lineis incrementi tenuibus oblique striati, ultimus postice 

 carinatus, carina versus aperturam sensim evanesceute, supra et 

 infra a;qualiter convexus, antice breviter descendens, circa medium 

 minute rugosus ; apertura transversa, lunata, intus albida vel 

 dilute lilacca ; peristoma album, dilatatum et reflexum, margine 

 columellari late expanso. 



Diam. maj. 23| millim., min. 19g; alt. 15. 



This species somewhat resembles H. aurora, Pfr. (Novitat. 

 Conch, vol. ii. pi. liv. figs. 9-11), in form, but is a trifle 

 higher in proportion to the diameter. It also differs in being 

 a smaller form and in having a larger umbilicus. The young 

 of this species is evidently sharply keeled at the middle, but 

 in the adult shell the keel gradually disappears towards the 

 aperture.
