Proc. Acad. Nat. Sc. Phil. Jan. 1887, p. 12. pi. 1, f. 1. A fine large trilobite unlike all other Cambrian species; differs from the type of the second fauna in having an ocular ridge extending from the front edge of the eye to the dorsal furrow, beside the glabella. All other parts of the head, thorax and pygidium relate it more closely to Ogygia than to any other generic form. The oldest Ogygia species {selwyni) Salter, in the Welsh Arenig rocks, is closer to O. hucTii of the Llandeilo rocks than to 0, Motzi. " It is unusual that a genus showing so little variation from Ogygia should occur at a much lower horizon in an area separated by over 5000 miles from the area where the species of Ogygia flourished at a later period," ^. ^., Wales and the Rocky Mount- ains.
