Rensselaeria ovoides, Eaton. In this extinct genus of the Silurian and Devonian, eleven species are known. Oriskany Sandstone, Schoharie, New York. FAMILY STRINGOCEPHALID^. Shell suborbicular, the hinge-margin rounded; under valve with deltidium and opening under the prominent beak; cardinal process large. No. 363. [728, Cast]. StringOCephalus Burtini, Defrance. Two Specimens. In this genus the ventral valve is pro- longed upwards into a very prominent, tapering beak, which is sometimes so curved forward as to rest iipon the dorsal valve. This latter has a very long cardinal process which quite crosses the interior of the shell, and is forked at the ex- tremity to meet the ventral septum. From the Devonian of Paffrath, Germany. FAMILY RHYNCHONELLIDiE. Shells oblong or trigonal, beaked; hinge-line curved; no area; valves articu- lated, convex, often sharply plaited; foramen beneath the beak, usually com- pleted by a deltidium; elongated .spiral arms. No. 364. Rhynchonella alta, Hall.
