State Missouri, I, 1884, pp. 15, 37, pi. 5.—Gurley, Journ. Geol., IV. 1896, pp. 90. 308. The original description is as follows: Frond consisting of stipes tiaving a common origin and rising above into a few stout, widely extended, bifurcating branches, averaging from L5 to 2 mm. in breadth, and terminating in dicbotomous points of equal thick- ness : texture corneous, with a striated surface. Owing to the striations the appear- ance of the surface is that of rough scales or fibers, somewhat resembling the exterior portion of /. iiluiiin- losus. In the growing state the branches appear to have been strengthened by longitudinal fibers— s<olid corrugations—and the cells to have been arranged vertically between Fig. them. A portion of the branches show a solid central axis, with a common canal surrounding it. The general arrange- ment of the branches resembles that of the horns of the American elk. The typical specimen consists of 6 principal stipes, each about 3 centimeters long, witli only a few branches. These stipes are united by a common runner (in the botanical sense), so that the whole organism is 5 centimeters broad and 3 centimeters high. Formation and localiti/.—This rare and beautiful species occurs in the shaly dolomites of the Blue Building beds of the Niagara formation at the " Jolly-cut," Hamilton, Ontario. A single specimen in the collec- tion of the U. S. National Mu- seum is known, but presents no ad- ditional in form a t i on. INOCAULIS PHYCOIDES Spencer. Iiiocanlh pliyorldcs Spencer.
