Pfeiffer's description is given above, and his figures copied 

 on pi. 31, figs. 61, 62, 63. The type was a more swollen form 

 than that ordinarily encountered, and further differed in hav- 

 ing 10 whorls, while the usual range is from 7 to 9. C. carnea 

 C. B. Ad. is universally admitted to be the same species, but 

 the name applies especially to the more slender and cylindric 

 form shown in fig. 64. 



The color varies from crimson or brownish-red to purplish 

 or light yellowish-brown. Some of the specimens from Stony 

 Hill are almost as purple as U. cylindrus. The striae are 

 rather widely spaced, separated by intervals of double their 

 own width. The circle of the peristome is interrupted above 

 for a short distance, the lip usually being brown-tinted; basal 

 keel is inconspicuous or almost obsolete. The internal pillar 

 is rather stout and strongly twisted spirally in the last four 

 whorls, less so but still perceptibly twisted above. The spiral 

 is stronger than in U.megacheila or U. amethystina. 



Specimens from Bellevue (pi. 31, figs. 65, 66, 69) are rather 

 large and somewhat swollen, and in color vary from purplish- 

 red to pale brown, always with a dark sutural border. Ex- 

 tremes measure:
