[From the Atlantic Journal and Friend of Knowledge. No. IV., page 142. Philadelphia, 1832.] [1491 New Fossil Shells of Pennsylvania, by C. S. Rafinesque. Among the 40 N. sp. of Bivalve fossils found this year on Sherman cr. in the Alleghany mts. I select those which are unequilateral as the most curious, and I shall describe 10 of them giving above the figures of 1, ranged under 3 new genera. All are Inequivalve. 1. N. G. Hemisterias Raf Shell transversal with 2 wings thus unequilate- ral, hinge with 2 teeth and an angular sinus outside at the beak, margin lobed —-~H. quadriloha fig. 1. Four obtuse lobes and 3 obtuse sinusses, lateral lobes like wings one much longer, an oblong furrow on each lobe, length half of breadth. 2. N. G. Telistrophis Raf. Shell unequilateral transversal with one wing on the longest side, hinge without beak, straight with a round impression inside at the apex, margin unlobed—T. Un^sala fig. 1. Shell convex, minute longitudi- nal curved strias, short side rounded, long side with a twisted obtuse wing, length 2-5ths of breadth.—Impression in Petrosilex, one inch, 3. N. G. Pleureterites R. Shell unequilateral transversal with- out wings, hinge more or less curved simple or with a wrinkle and a beak, margin unlobed.—The name means irregular sides, Telistro- 2)his means spotted hinge, and Hemisterias means half star
