“In form it is more globose and inflated than the other sinistral 
Helices, excepting H. (Ariophanta, Beck) cicatricosa, Mull. (China, 
Woosung), guesita, Desh., and bajadera, Pfr. In figure it more 
nearly approaches H. quesita, Desh. (Fér. t. 10 B. figs. 10, 12), 
but differs in the narrow umbilicus, smaller number of whorls, with 
a greater size, as well as in colour, texture, and less developed 
peristome.”
