Discussion

C. binghamae is closest to the sympatric C. patae in both shape and size, but differs in being a smoother shell by lacking axial pilcations and heavy beading, and by having a different color pattern, consistently composed of a checkered mid-body band and darker anterior tip. The base color of C. binghamae is also more variable than that of C. patae which is consistently in shades of pink or lavenders with dark orange scattered flammules. C. patae also lacks of rows of tiny dots seen on C. binghamae.
