This species is closely allied to H. strabo, but apparently con- 

 stantly separated by the creamy peripheral band and deep purplish- 

 black peristome. The type is figured on pi. 17, figs. 40, 41. 



The variety called yulensis by Brazier (pi. 2, figs. 28, 29, 30, 31) 

 is smaller, with the " spout" of the aperture less developed. It must 

 however be regarded as a variety or form of the tayloriana. 



H. ALBOCARINATA Smith. PL 1, fig. 5. 



Short-conical, imperforate, thin, semi-pellucid, pale corneous, en- 

 circled by an opaque-white carina ; whorls 5, moderately convex, 

 obliquely roughly striate, the last whorl acutely keeled at the peri- 

 phery, sculptured below with rugose concentric strise, ornamented 

 with few, interrupted, white opaque lines, shortly descending in 

 front, margined with buff or milk-white behind the lip. Aperture 

 oblique ; peristome white, narrowly expanded and reflexed, outer 

 margin sinuous, columellar margin thickened, appressed parietal 

 callus thin. Alt. 17, greater diam. 24, lesser 20 mill. (Smith.} 



South Cape, Neiv Guinea.

The central keel is rather sharper and the texture more transparent 

 than in H. tayloriana, but it may prove to be an albino form of that 

 species.
