1. CYLINDROVERTILLA KINGI (Cox). PL 5, figs. 1, 2, 3. 



The shell is sinistral, rimate, ovate, between cinnamon and 

 fawn color. Surface glossy, very closely, minutely striate, 

 the strias oblique, very low, usually most distinct on the 

 penult whorl, partly effaced or in part replaced by irregular 

 granulation 011 the last. The apex is obtuse. Whorls are 

 rather strongly convex, the last having a wide or strong, 

 rounded, striate crest behind the outer and basal lips, of a 

 dull orange-cinnamon color; behind the crest it is somewhat 

 flattened laterally, convex below the suture. The aperture is 

 somewhat oblique, shortly piriform, the peristome expanded, 

 heavily thickened within by an orange-cinnamon or paler 

 callous ridge. The angular lamella is strong, white, its 

 emerging outer end low, curving to join (or nearly join) the 

 termination of the outer lip. Columellar lamella white, rather 

 small and short, almost tuberculiform. The upper palatal 

 fold is short, not emerging to the callous rib. Lower palatal 

 fold smaller and a little deeper within. 



Length 1.95, diam. 1.1 mm. ; 5 whorls.
