The result of the Tendaguru expedition to German East Africa has been the discovery by Drs. W. Janensch and E. Hennig of some forty Dinosaurs, ranging in size from forms larger than Diplodocus to ones as small as a pointer dog; these finds may be extended since Dr. H. Reck has proceeded to the locality with the intention of digging for a further year. In a paper by Dr. Hennig on the possible extension of the Dinosaur deposits this author calls attention to the discovery by the late Dr. W. G. Atherstone of Dinosaur remains in the Wood Bed (Lower Cretaceous) of Bushman's River. In his description, published in the Eastern Province Magazine, Grahams town, 1857, Dr. Atherstone states that a large part of the skeleton as well as the skull was discovered, but the only parts so far describe are two skulls named by Owen Anthodon serrarius. Very little is known of this form, and Zittel places it in the Pareiasauridae a a Karroo reptile. Dr. R. Broom described another Dinosaur from the same beds at Despatch, near Port Elizabeth, under the name Algoasaurus Bauri. Messrs. Eogers and Schwarz mention Dinosaur bones as occurring in the sandy beds along the Bezuidenhouts River in Uitenhage, and some detached bones and teeth from these beds are exhibited in the Albany Museum, Grahamstown. All these remains are of comparatively small animals for Dinosaurs. In the recent Whitsuntide holidays Professor E. H. L. Schwarz took his students to the Bushman's River, and in Dr.
