Covered perforate, globose-turhinate, solid, sharply obliquely 

 striate-crenulate ; tawny, and under a subpearly epidermis having 

 a number of brown-bluish bands and minute irregular spots ; white 

 at the suture. Spire conoid, vertex acute, brown. Whorls 4?, con- 

 vex and separated by an impressed suture. Last whorl large, a little 

 descending in front, subconstricted in the middle and then very 

 obscurely subangulated, the base little convex. Aperture ovate, 

 very oblique, the throat brownish-pearly ; peristome white, margins 

 converging, joined by a pellucid brown callus. Lip expanded and 

 reflexed throughout, subflexuous above, the base little curved, col- 

 umellar margin subarcuate, its base dentiform and truncate, brown 

 spotted within, and expanded at the insertion above the umbilicus. 



Alt, 23, greater diam. 36, lesser 29 mill. (T.C.)

Covered perforate, globose-turbinate, solid, obliquely rudely

 ovate, very oblique, throat white ; peristome white, the margins con- 

 verging and joined by a thin pellucid callus, expanded and reflexed 

 throughout ; basal margin nearly straight ; columellar margin ex-
