132 HELIX-HADRA. 



pale, and that of the umbilicus dusky. Whorls six, well rounded, 

 with coarse irregular striae of growth, the suture deeply impressed. 

 The aperture is large, rounded, its diameters about equal ; throat 

 livid, becoming darker near the lip; peristome slightly reflexed, 

 whitish, the basal portion nearly horizontal, and the extremities 

 widely separated, columella rapidly widening, so as to leave a mere 

 chink of the umbilicus uncovered ; a very thin coating of enamel 

 unites the two lips. ( Gould.} 



Diarn. about one inch, axis four-fifths inch.

See Gould (I. c.) for notes on the animal and its peculiar mode of 

 progression. The observations on this last point need confirmation. 

 The periphery is marked by a trace of the keel, so obtuse as to escape 

 superficial observation, in the specimens before me. This species has 

 been considered a synonym of H. lessoni Pfr., but on wholly insuffi- 

 cient grounds. It is the type of Gould's group Badistes. H. coriaria 

 Pfr. is in all probability a synonym for H. gulosa. 



H. CORIARIA Pfeiffer. PI. 43, figs. 48, 49, 51. 



Shell almost imperforate, globose-depressed with low-conoidal 

 spire, obsoletely keeled at the circumference; uniform chestnut 

 colored all over, or a little darker at suture and umbilicus ; surface 

 densely and very minutely granulate, smoother around the um- 

 bilicus. 



The color is darker than in H. grayi, and the granulation has a 

 somewhat different pattern. There are rather rude, coarse, oblique 

 wrinkles of growth, most obvious at the suture. The upper whorls 

 of the spire are lighter in color. Whorls 5, convex, the last de- 

 scending below the blunt carina in front. Aperture oblique, flesh- 

 colored inside, of a rounded-lunar form ; outer lip a mere trifle ex- 

 panded, pink; columellar lip reflexed, dilated, covering the um- 

 bilicus except for a narrow chink. 



Alt. 25, greater diam. 30, lesser 25 J mill.
