Shell umbilicated, orbicularly-depressed, rather coarsely rugosely 

 ribbed, especially at the suture, rather thin, moderately shining, red- 

 dish-chestnut with a pale spiral band under the suture ; spire widely 

 and obtusely conical ; whorls 5, convex, last whorl sometimes indis- 

 tinctly angulated, not descending in front ; base smoother and more 

 glossy than above, with a wide yellowish patch surrounding the dark 

 circumference of the umbilicus, which is moderate and deep ; aper- 

 ture diagonal, lunately-ovate ; peristome simple, thin, straight, the 

 dark columellar margin dilated above and reflexed, to cover ? of the 

 umbilicus. ( Cox.)

A very variable species ; an examination of a series collected by 

 Mr. Masters shows the ground color to range from pale reddish- 

 horny to very dark reddish chestnut, the band is seldom very well 

 defined, is often very indistinct, and occasionally wanting ; and the 

 yellow patch on the base may be indistinct or absent. Two speci- 

 mens from Flinders Island are of a smaller variety ; but there can 

 be no doubt as to specific identity, for one shows very plainly, not 

 merely, in addition to similarity of sculpturing, &c., the pale patch 

 on the lower surface, but also the spiral band below the suture.

Shell sub-globose, strong, coarse, obtusely keeled at the periphery, 

 of a pale chestnut-brown which is here and there diluted so as to 

 form large, irregularly disposed clouds, and sometimes bands, the 

 shades blending with each other ; the region of the apex is generally
