Smaller than H. nuxdenticulata, without oblique wrinkles, and 

 with different armature of the outer lip. H. crassidens Pfr. (fig. 21) 

 is founded on specimens with the two lip-teeth subequal. 



H. PARILIS Ferussac, PI. 29, figs. 22-24. 



Imperforate, depressed-globose, solid, opaque, shining, brown or 

 yellowish, with two encircling dark bands often ill-defined, and 

 numerous irregular, zigzag, bright golden markings ; surface marked 

 by incremental stride and obliquely descending fine dense wrinkles, 

 which are concentric on the base ; spire low, rounded, very obtuse ; 

 apex flat ; suture linear ; whorls 4, penultimate nearly as wide as 

 the last; body-whorl commencing subcarinate, becoming rounded, 

 gibbous and then constricted behind the aperture, deflexed above ; 

 aperture very oblique, transverse, oblong or trilobed ; peristome 

 heavy, convex, brownish, outer lip bearing above a more or less 

 developed callus or tooth, basal margin thickened within but not 

 toothed; terminations of the peristome remote, the upper one pro- 

 duced downward upon the parietal wall in a tubercular tooth, and 

 connected with the columellar end by a slightly thickened callus.

Obliquely wrinkled like H. uuxdenticulata, but smaller, with 

 different peristome and variegated coloration. 



H. pseudoparilis Grat., is probably an immature specimen of this 

 shell.
