. Acadian geology : the geological structure, organic remains, and mineral resources of Nova Scotia, New Brunswick, and Prince Edward Island. Geology -- New Brunswick; Geology -- Nova Scotia; Geology -- Prince Edward Island; Paleontology -- New Brunswick; Paleontology -- Nova Scotia; Paleontology -- Prince Edward Island. Clidophomis concentricus, n. s. (Fig. 204). Shell sub-equilateral, very broadly oval-ovate, the anterior end the broader; height nearly four-fifths the greatest length; anterior side a little shorter and more broadly rounded at the extremity; a slight depressed sinus on the posterior umbonial slope, which is more anterior than in the preceding species. Surface marked by even band-like concentric striae; shell thin; a linear curving clavicle extends from the cardinal line just anterior to the beak more than half way to the base. The prominent points of distinction between this and the preceding shell are the nearly central beaks, the band-like striae, and the curving clavicle with the broad and nearly equal extremities of the valve. Arisaig. Clidophorus erectus^ n. s. (Fig. 205). Shell somewhat rhomboid- ovate, the height and length about equal; umbones prominent, beaks nearer the anterior end, somewhat curved and elevated; posterior.
