sauropod. It measures approximately 15 inches from top of skull to alveolar border. I have traced it forward about 18 inches from the posterior portion of the skull. The teeth are much like those which Marsh referred to Brontosaurus (Apatosaurus) and like those in parts of skull which we found with the Apatosaurus like skeleton -- No. 240 (I think that is the no.).

	About two days ago we found another disarticulated skull (or parts of one) apparently of the same kind. As nearly as I can judge now the teeth and maxillaries are the same. We have not yet finished exploring for the latter. It seems that at last we are finding the larger type of sauropod skull.
