“From Hall (1861, p. 19): “Body pyriform, base truncate, gradually ex- panding to the top of the radial plates; dome rounded and more or less convex. Basal plates four, strongly nodose, extended laterally, and one half or more of the entire width occupied by the articulating facet of the column, which is deeply inserted.”
