All the above trilobites have been recorded previously with theexception of Olenoides cf. quadriceps and Oryctocephalus Beynoldsi,, the latter of which I have much pleasure in naming in honourof its discoverer. The specimen is of peculiar interest as it consistsof a complete individual in perfect preservation, whereas our previousknowledge of the genus has been restricted to the disconnected head-shields and pygidia of Orycto. primus described by fiestored outline of Onjctocephahts Reynoldsi, sp. nov. Middle Cambrian: MountStephen, Field, British Columbia. Magnified about four times natural size. Oryctocephalus Eeynoldsi, Head-shield transversely semicircular, broad, short, more thantwice as broad as long. Glabella elongate, cylindrical, sides parallel;reaches margin; front rounded ; surface marked by four pairs oftransverse furrows. The three anterior pairs of transverse furrowsare equidistant, and terminate in small deep pits within the marginof the glabella; each furrow is shallow and arches slightly back-wards in the centre. A shallow groove parallel to the axal furrowconnects the pits on each side longitudinally. The fourth transversefurrow crosses the base of the glabella at a distance from the thirdfurrow rather greater than the latter from the second or the second 1 Owing to slight crushing the glabella in our specimen appears to be slightly?wider in front than at the base. 360 F.
