HELIX-HADRA. 157 



Smaller, lighter colored and more depressed than H. gratiosa and 

 most other species of Sphserospira, the surface often appearing 

 denuded of cuticle, and of a pinkish tint; spire low; whorls 5& to 

 to 5f, slightly convex, the last deflexed in front, convex all over. 

 Aperture rounded, pinkish-fawn-color inside, showing the band ; lip 

 expanded, dilated at the columella, closely adherent over the umbili- 

 cus and spreading in a deep brown callus over the parietal wall 

 and into the mouth. Alt. 23, greater diam. 25, lesser 22J mill.

The greatest circumference of this shell is higher on the whorl 

 than in most of the species, and the body-whorl is notably convex 

 in every part. The coloration is lighter than in Sphserospira 

 generally. 



H. ANDERSON: Cox. PL 23, fig. 68. 



Shell imperforate, rather thin, depressedly globose, finely striated, 

 yellow brown, with three or more rather narrow dark chestnut bands 

 round the center and lower part of the body-whorl, and one beneath 

 the suture ; whorls 6tr, almost flat, gradually increasing in size ; aper- 

 ture diagonal, elongately lunately rounded, lip dark, as is also the 

 covered umbilicus ; margins converging, thin, slightly expanded, 

 columellar margin triangularly dilated, adnate, occluding the um- 

 bilicus and sunk below the marginal line of the aperture, causing 

 the latter to be sharply angled. ( Cox.)
