Very like coarctatus in form, but widely differing in sculpture, 

 and especially in the aperture, which is not contracted, the peristome 

 not thickened within nor sinuous (Pfr.). 



Reeve's figure, here copied, which is said by Pfeiffer to represent 

 his schmidti and not coarctatus, shows a different color pattern from 

 that described by Pfeiffer, being " white, encircled round the upper 

 part with brown black interrupted lines, round the lower with bands, 

 lip ivory white'"
