Discussion

C. bayeri closely resembles the Venezuelan C. paraguana but differs in having a lower, canaliculated spire, in having two sulci around the shoulder below the carina, and in having bands of tiny vertical lines instead of rows of dots. C. bayeri appears to be closer to members of the C. gradatus species complex from the Panamic Province eastern Pacific than it does to other Caribbean cones.
