Excerpt from The Devonian Brachiopoda of the Province of Par???, Brazil Shell small and slightly asymmetrical in shape; length and breadth nearly equal, giving an irregularly subcircular outline to the shell, which is somewhat attened posteriorly; hinge line straight and slightly shorter than the width of the shell; cardinal extremities not preserved in the single specimen obtained. Ventral valve very convex (but rather less so than is usually the case in this genus), quite strongly curved from side to side, and strongly and nearly regularly curved from the beak to the front, the point of greatest prominence of the valve being, however, slightly posterior to the middle. Beak rather small, but strongly arched and regularly rounded, and projecting some distance behind the hinge line. The convexity Of the umbo broadens with moderate rapidity forward, leaving the portions of the valve bordering the cardinal extremities slightly and irregularly attened. The want of symmetry in the ventral valve results from the beak and more promi nent line of curvature lying a little nearer the right margin than the left. Dorsal valve unknown.
