These figures indicate that the species is one of the largest as well as the most extravagantly orna- mented of all forms of Lichas. It is surpassed in dimensions only by Terataspis grandis and Uralichas ribeiroi, the lords of this tribe. Equipped with cerements of mortality, successors of this genus Gaspelichas are not to be expected. Lower Devonic. Grande Greve, P. Q. Lichas bellamicus nov. This is a species of medium dimensions having the lobation of cephalon and the outline of the pygidium very similar to the cor- responding parts in the prevalent forms of Lichas from the Helder- bergian. The frontal lobe is pyriform, not elevated or bombate but uni- formly convex, without abrupt posterior slope; the lateral furrows. Lichas bellamicus are deep and the converging lateral lobes elongate, of about equal width throughout and divided only by an extremely faint cross furrow. The grooves dividing these outer glabellar lobes forming the fixed cheeks are very shallow, and these cheeks are convex and elongated about the eye lobes. The cephalon appears to be bounded by a smooth margin which is flat in front. The entire surface except the furrows is coarsely tubercled and it would.
