DESCRIBED AS Cymakra granata

Cymakra (= Mitromorpha) granata most resembles the Californian C. gracilior (Tryon, 1884), but has a smaller protoconch, less inflated whorls, a longer aperture, 3 rather than 4 cords on the first and second postnuclear whorls, more numerous cords on the body whorl, and weaker columellar plicae. The name is a Latin adjective, having many grains or seeds, suggested by the sculpture of fine granular beading.
