There are three specimens of this species in the Woodwardian Museum, viz.: (1) Salter's fine original specimen (a 954) from the Wenlock Shale of Malvern, belonging to the first part of the Fletcher Collection, acquired prior to 1873; (2) a poor specimen probably from the same collection and horizon, locality unknown; and (3) an almost perfect specimen, also from the Wenlock Shale of Malvern, belonging to that part of the Fletcher Collection recently presented by Mrs. Fletcher. This specimen will be designated the Fletcher specimen in distinction to Salter's original specimen. Both these specimens show almost the whole trilobite preserved in excellent condition, and from them the following description has been drawn up.
