Glauconome GRANDIS. M'Coy. (PL XXVIII. fig. 3). Sp. Ch.—Stem less than twice the thickness of the lateral branches; lateral branches rather more than the width of the midrib apart, obscure ; lateral branches carinate, and bearing two alternating rows of very small, round, prominent pores, which indent the margin slightly ; the stem is obscurely carinate, and has usually two rows of small, round, prominent pores, which do not alternate, or reach the margin ; one at the origin of each lateral branch, and three between one branch and the next. The small size, and great number of the pores distinguish this from every other species of Glauconome I know. It is a very large species. Length of imperfect specimen one inch nine lines ; length of lateral branches two lines ; diameter of midrib about half a line. Collected by Mr. Charles B. Newenham of Cork, who kindly presented the specimen figured. http://www.thefossil...-carboniferous/
