420 Mr. E. A. Smith on some Land-Shells 



peculiar in having no black callus connecting the columella 

 and extremity of the outer lip. 



Helix (Acavus) lati'axis, Smith. (PL XV. fig. 7.) 



A single specimen from the foot of the Owen Stanley 

 Mountains, British New Guinea, differs from the type* in 

 having the last whorl very much more sharply keeled at the 

 periphery, the aperture consequently also being more pointed 

 in front. The epidermis upon the body-whorl is disposed in 

 ten spiral zones instead of six, five above and five below the 

 carina. Being a younger shell, the interior has not been 

 coated over with the bluish-white callus as in the adult type, 

 and the external banding is, on account of the comparative 

 thinness of the sliell, obscurely visible. 



Messrs. Brazier f and Tapparone Canefri :j: consider this 

 species the same as H. zeno of Brazier, described in the year 

 1876. This can scarcely be correct, as certain terms of the 

 description are not applicable to H. latiaxisy which cannot be 

 described as '^ globosthj turhinatedj'' nor " thin,''^ nor ^'Jlesh- 

 colour ; " and the spiral bands do not " in front all run into one^ 

 The omission of any mention of the acute angulation of the 

 body-whorl also induces me to consider this species distinct ; 

 and, finally, Mr. Brazier having now sent me a specimen of 

 this species marked " Helix, sp. nov. (only specimen): foot of 

 Mount Owen Stanley Bange, British New Guinea," strongly 

 indicates that the two forms are specifically different, for it is 

 very unlikely that he would have sent a specimen of his own 

 species thus labelled. 



Helix {OeotrocJius) lacteolota. (PI. XV. fig. 9.) 



Testa conica, perforata, zonis pluribus lacteis et nigro-fuscis lacteo 

 illitis cincta ; anfractus 5, liueis incrementi ohliquis striati, ulti- 

 mus ad peripheriam rotundatus, infra convexiusculus, antice 

 paiilo descendens ; apertura perobliqua, perist. versus purpureo- 

 Bigrescens, longe intus caerulea ; peristoma album, undique ex- 

 pansum et paulo reflexum, margine columellari superne livido- 

 fusco, late dilatato umbilicum partim obtegente. 



Diam. max. 36 millim., min. 28, alt. 34. 



Hab. Foot of Owen Stanley Mountains, British New 

 Guinea. 



This handsome species, in some respects, bears a consider- 

 able resemblance to H j^lurizonata, Adams and Reeve, from
