There is some variation in the lamellae of the axis, but the 

 thin wide lamella below is not so prominent in the last 

 three whorls as in U. humboldtiana, and the others are more 

 nearly equal in size. Ordinarily there are lOi/2 to 12 whorls. 

 In a specimen with the spire complete (fig. 82 x 6) there are 

 161/2 whorls, 6!/2 of them above the plug, the position of which 

 is marked by a change in color. The apex is rather large and 

 smooth. Figures 82, 83, 86 are magnified 6 diameters.
