The Annals and magazine of natural history; zoology, botany, and geology . re the coracoid,scapula, and a part of the humerus. The coracoid is imper-fectly preserved; it appears to have been about 4 inches long,and 2 inches wide at the distal termination, very thin, andconvex on the superior side; its proportions are more in accordwith the Emydian type than with that of the marine scapula measures nearly 1^ inch from the articular sur-face to the part where the scapula proper branches at about aright angle from the part called the precoracoid. This latterportion is small, subcylindrical, a little compressed, and about2 inches long. The scapula is fractured, so that its length isnot known. So far as the remains preserved indicate affinities, the genusmay as well have been Chelonian as Emydian, but cannot withcertainty be affiliated to either type. Prof. Owen observes that this carapace is understood to 230 Mr. H. G. Seeley on Chelonian Remains have formed part of the same individual turtle as the skull(t. ix.) on which I now offer a feAv ]?ack view of the skull of Chelone hamcensis (Woodward), half uat. size,showing the large hyoid bones in shade; between them is seen thetripartite occipital condyle, with the conical foramen magnum aboveit, and laterally the outlines of the other occipital bones. Chelone jjlammentum (Owen), Proc. Geol. Soc. 1849, pi. ix. This skull has been very incorrectly figured and imperfectlydescribed. It is wide behind the orbits, but in front of them tapersmore abruptly from side to side and from above downward thanshown in the figure, somewhat resembling Chelone caouanna. The nostril is subquadrate, broader than high, about -j-f ofan inch wide, and small for the size of the skull when com-pared with recent marine Chelonians. The premaxillary is alittle worn; but the extreme length of the skuU from the pre-maxillary to the occipital condyle is 5 inches; the antero-posterior length to the termination of the
