Paul, et.al,

This is definitely Cyclophorus daraganicus Hidalgo, 1888.  The
pattern and shape are characteristic of the species.  C. prietoi has
a slightly channeled suture and tigrinus has more defined and more
numerous spiral cords.  The illustration I have in Hidalgo (1891) is
identical to Paul's shell.  Zigzag patterns in Cyclophorids are a
common occurrence; the pattern on some specimens being more sharply
defined than others.

Also note that Wolfgang's spelling "daraganicus" is correct.  An
extra "n" slipped in for the caption in Compendium.
