horizontal, thickened by a callus, columellar margin dilated, thick- 

 ened, partly closing the narrow umbilicus. (Mlldff.*) 

 Alt. 21, greater diam. 27*, lesser 25 mill.

Very near to If. sucdncta, but more conic with flatter whorls, the 

 last one very acutely keeled, much more compressed beneath, and 

 remarkably flattened behind the mouth, causing the basal lip to be 

 horizontal instead of arcuate. Described from a single specimen. 



H. STENOZONA Mollendorff. PI. 27, figs. 4, 5. 



Shell umbilicated, conoid-depressed, thin, obliquely arcuately 

 striatulate, decussated by very delicate spiral lines, straw colored, 

 painted with a very narrow brown peripheral band. Whorls 5*, a 

 little convex, the last obtusely angulated at the periphery, slightly 

 deflexed in front, subcompressed on the base, subangulated around 

 the umbilicus. Aperture oblique, rotund-lunar, the peristome nar- 

 rowly expanded, a trifle reflexed, whitish, margins joined by a very 

 thin callus, the basal margin subhorizontal, callously thickened, the 

 columellar margin dilated. (Moll.') 



Alt. 14J, greater diam. 23, lesser 19 mill.

H. stenozona MOLL., Jahrb. D. M. Ges. 1884, p. 385, t. 9,f. 5, 6. 



A species closely allied to H. sucdncta H. Ad., especially to its 

 smaller forms, but smaller, thinner, somewhat more widely umbili- 

 cated, the last whorl much more bluntly angulated, the spiral stride 

 finer and more regular. The color is simply straw-yellow, with a 

 very narrow reddish brown girdle. (Moll.}

Shell globose or globose-depressed, imperforate or half-covered 

 umbilicate, thin, somewhat solid, greenish-amber-colored encircled at 



the periphery by a narrow red zone; cancellated by broad, con- 

 spicuous oblique and concentric stria? ; shining ; spire subelevated or 

 much compressed ; whorls 4 to 5, a little convex, separated by linear 

 sutures ; the last whorl large, and angulated below the color-band, 

 convex, not descending in front; aperture little oblique, oblong- 

 lunar, sinuous; peristome white, thickened, straight, scarcely reflexed,
