Pfeiffer states 1-3 that spiral lines are visible under a lens in this species, but neither 
in Fischer and Crosse’s specimen, which comes from the same source as Pfeiffer’s, nor 
in that contained in Patel’s collection are such strize to be seen. Probably they are 
irregular and only present in some specimens, as is sometimes the case in the species 
of this and of the allied genera. Fischer and Crosse have established a variety, and 
Strebel even a new species, upon such specimens. Mr. Edgar Smith informs me that 
in his opinion “ O. paradensis, notwithstanding the very faint spiral striation, is a rather 
unsatisfactory species.”
