(Original.) the union, among themselves, of the septa in the counter quadrants, and their separation from the alar septa. Counter septum not reaching the center. A pseudo-columella, is formed by the junction of the longer septa in the center. Found in the lower Moscow shale at Eighteen Mile and Morse creeks (rare). Genus CRASPEDOPHYLLUM. Dybowsky. [Ety. : Krospedos, an edge; phyllon, leaf.] (Beschr., von neuen Devonischen Artea der Zoantharia Rugosa, p. 153.) Corallum simple or fasciculate; corallites commonly cylindrical, each with a moderately-deep calyx and well- developed epitheca. A secondary central wall is present, which is not crossed by the septa, the longer of which join it to the outer wall. Inner area with tabulae, outer with dissepiments. Upper edges of septa carinate. Craspedophyllum abchiaci. Billings. (Not figured.) (Diphyphylhun archiaci. Billings. Canadian Journal,, p. 260, Fig. 8.) Distinguishing Characters.— Heads consisting of parallel nearly straight cylindrical corallites, nearly or quite in con- tact with each other; young stems added by lateral or marginal gemmation; central tube small, apparently want- ing in some corallites; dissepiments numerous; epitheca showing numerous lines of growth, and sharp-edged annula- tions. Some corallites exhibit sudden constrictions of growth. Found in the Hamilton group (Encrinal limestone ?) on the shore of Lake Erie
