lip, but much less pronounced, in other respects being totally 

 distinct. The peristome in H Tapparonei is most remarkable, 

 being so peculiarly contracted that the most prominent part of 

 the whorl is at the carination. It is broadly margined with 

 intense black, with the extremities united by a callosity of 

 the same colour, which extends upon the penultimate whorl 

 within the aperture as far as the eye can reach. The 

 rest of the interior is rosy white. The outer lip at the 

 margin is only a little thickened and reflexed ; but at fhe 

 base the reflexion is somewhat greater, gradually widening 

 as the columella is approached. With the exception of the 

 black peristome, the base of the shell is uniformly cream- 

 colour, which towards the front is rather yellower. The 

 upper surface, however, is ornamented with spiral bands of 

 a lilac-rose tint, in some specimens ill defined or coalescing, 

 so that this colour predominates. 



Helix (Geotrockus) latiaxis. 



Testa subsolida, imperforata, depresse trochiformis, in medio medio- 

 eriter acute angulata, sublilacea, apieem versus livido-nigrescens, 

 epidermide caduca, fusca, zonis concentricis disposita ornata, un- 

 dique minute concentrice granulata, lineisque incrementi obliquis 

 sculpta ; spira mediocriter elevata, marginibus vix convexis, apice 

 subobtuso. Anfractus quinque, convexiusculi, celeriter aceres- 

 centes, sutura lineari discreti ; anfr. ultimus inferne paulo con- 

 vexus, antice maxime oblique descendens, pone labrum leviter con- 

 strictus, zonis sex, tribus supra, tribusque infra angulum ornatus. 

 Apertura valde obliqua, intua cseruleo-alba ; peristoma saturate 

 nigrum, undique late expansum, marginibus callo crassiusculo nigro 

 junetis; columella latissima, complanata vel concava, margine 

 aperturam versus subrosaceo, in medio parum prominulo. 



Longit. 28 millim. ; lat. max. 38, min. 32. 



This is a very handsome shell, and quite unlike any as yet 

 described from New Guinea, with the exception of H. brumeri- 

 ensis, Forbes. This is similarly sculptured, has a broad black 

 expanded lip, but is not angled at the periphery or spirally 

 banded in the same manner. 



Helix (Obba) oxy stoma. 



Testa anguste umbilicata, depressa, in medio acute carinata, incre- 

 menti lineis striata, undique rugis subconcentricis, confertis, parvis 

 Bculpta, submalleata, flavescens, ad apieem rufescens, zonis duabus 

 nigreseentibus plus minusve interrupts (una supra altera infra su- 

 turam) maculis sparsis, irregularibu9, nigris rufisque peculiariter et 

 insigniter picta ; spira parum elevata, marginibus vix convexis.
