An abundant and variable shell. Sometimes it is elevated, conical, 

 sometimes depressed, often carinated at the periphery. There is also 

 much variation in the coarseness of the sculpture, the size and color. 

 Umbilicated specimens are not infrequent. Figs. 1 to 5 represent 

 typical examples. 



A small form is rather lighter in color than the types. It meas- 

 ures alt. 10, diam. 15 mill. Others measure, alt. 14, diam. 18 mill.

Light yellowish, with two dark chestnut bands, the lower one 

 often lost, generally rather more depressed than the type, and um- 

 bilicus often open. Dimensions the same as in the type.

Umbilicate, depressed conical, solid, whitish, strongly, acutely, 

 lirulate all over ; spire conical ; whorls 6 }, very gradually increas- 

 ing, the last subangular at the periphery, not gibbous behind the 

 aperture, a little descending anteriorly; aperture quite oblique, 

 rounded-lunar ; peristome narrowly reflexed, margins converging, 

 the columella bearing a strong callous tooth within. Umbilicus 

 deep, partly covered by the reflexed columellar lip. 



Alt. 19-20, diam. 30-32 mill.

Easily recognized by the columellar tooth, the lack of dilation 

 and constriction of the last whorl behind the aperture, etc. Not a 

 common species.

Imperforate, globose-conoid, solid, obliquely striatulate and 

 spirally delicately, regularly striate ; yellowish with two or three 

 spiral bands of brown ; spire conoidal, obtuse ; whorls 6, the last 

 compressed on the base opposite the aperture, and with a deep curved 

 scar or trench, producing an elongated fold or tooth inside the whorl ;
