70 HELIX-PAPUINA. 



having scattered purplish-translucent dots. It is larger and more 

 solid than H. eros, with less expressed keel, more vivid coloring, and 

 wider umbilicus. 



H. EROS Angas. PI. 15, fig. 98, 99, 100, 101. 



Narrowly perforated, depressed trochoidal, about equally convex 

 above and below the acute peripheral keel. Surface obliquely striat- 

 ulate, densely sculptured with close, fine forward-descending wrinkles, 

 becoming concentric on the base. Spire low-conoidal, whorls 4?, 

 convex, the earlier 2 or 3 red, the remainder opaque, buff, with 

 scattered grayish-translucent dots, and a brownish band above and 

 below a whitish peripheral zone Last whorl convex above and 

 below, generally shortly deflexed in front. 



Aperture oblique, subrhombic, more or less streaked and dotted 

 inside on a white ground. Peristome thin, pink, expanded, the basal 

 and columellar margins reflexed, the latter straightened, having an 

 obsolete fold of callus in the middle and dilated at the insertion, 

 nearly closing the narrow umbilicus.

This species resembles H. fringilla in the red or pink upper whorls, 

 and the callous fold on the columellar lip ; it differs in being per- 

 forated, smaller, thinner, and sculptured in a totally different 

 manner. It is, in fact, very closely allied to H. lienardiana, but is 

 smaller, with narrower umbilicus and far less vivid coloring. Lives 

 upon trees. 



H. REDEMPTA Cox. PI. 3, figS. 40, 41. 



Shell obicularly convex, imperforate, obliquely finely striated 

 from above downwards and backwards with strait striae, and on the 

 last two whorls from behind forwards with interrupted malleated 

 striae, of a dull opaque white color, apex pink, variously ornamented 

 with irregular dark chestnut spots, or with two or more regular 

 broad bands ; spire bluntly coniform ; whorls 5, slightly convex, last 

 sharply keeled and shortly deflected in front, base flattened ; aperture 

 quadrilateral, beaked at the periphery of the last whorl, margins 

 joined by a thin pink callus ; peristome pink, narrowly reflexed ;
