Gay Head, Martha’s Vineyard.—In 1900 (Bull. Geol. Soc. Amer., vol. XI, p. 459, plate XLII, fig. 2), J. B. Woodworth reported finding an astragalus of a horse in an osseous conglomerate, regarded as belonging to the Miocene. It was identified by Professor H. F. Osborn, who remarked that it resembled closely the same bone of some Pleistocene horses. From this conglomerate have been obtained bones of whales, supposedly also a skull of a walrus. While the size of the astragalus suggests more that of a Pleistocene horse, it is possible that there was some large Miocene equid that lived there. The present writer is inclined to believe it will be found that the astragalus came from one of the older Pleistocene deposits recognized as present at Gay Head.
