6, slowly increasing, moderately convex, scarcely descending in 

 front ; periphery with faint keel, base convex, smoother than the 

 upper surface, aperture diagonal, roundly lunate ; peristome white, 

 simple, straight, margins scarcely approaching, expanded and re- 

 flected anteriorly, columellar margin rather broadly reflected on the

The following two varieties come from Gould Island, and are 

 much smaller than those from the mainland : 



Var. a. Thinner, darker in color on the upper surface, granula- 

 tion finer ; light yellowish band following the suture spirally to the 

 apex. Alt. 8, greater diam. 13, lesser 10 J lines. 



Var. b. Thicker, light straw yellow, upper surface granulated, ob- 

 liquely rugosely striated, keel more distinctly seen on the periph- 

 ery ; peristome scarcely reflected at the columellar margin. Alt. 7, 

 greater diam. 11 f, lesser 9f lines. (Brazier.)

Shell umbilicated, globose, inflated, very thin, distinctly obliquely 

 striated, granulated from left to right, taking somewhat of a zig-zag 

 form, smoky yellow, with a chestnut band under the suture having 

 a faint broad one above, giving it a darker color ; body-whorl from 

 the periphery dark chestnut ; spire somewhat globular, suture 

 smooth; whorls 5J, slightly convex, slowly increasing, the last 

 roundly convex, descending a little in front ; aperture nearly diag- 

 onal, roundly lunate ; peristome below slightly raised somewhat in 

 the form of a small obtuse callus-like tooth, bluish white, very little 

 expanded or reflected ; margins rather distant, joined by a thin, 

 bluish-white callus ; columellar margin broadly expanded and re- 

 flected on the umbilicus. (Brazier.) 



Alt. 17, greater diam. 23, lesser 18 lines.
