Distance of each section from the beak: 1 — mm. 2— 3— 4— .5 mm. 7— In a shell mm. in length the dorsal septum persisted for mm. and the ventral septum was present 9 mr anterior to the beak. The chief distinguishing features of Rhynchocamara are the camereUoid exterior, short hinge-line, ventral spondylium duplex, and rhynchonelloid cruralium. From Camerella it differs in outline, the former being more globular, and in the structure of the dorsal valve. The cruralium duplex of Camerella is long and nar- row, extending for perhaps one-fourth the length of the valve, whereas in Rhynchocamara it is confined to a small region beneath the beak.
