progress made during the last twenty-five years on that continent, 

 while two journeys to South America, in 1896 and 1907, have 

 furnished material for many original papers. During one of his three 

 visits to Greece, in 1901, he was officially commissioned hy the 

 Trustees of the British Museum to supervise diggings at Pikermi 

 for fossil mammals, of which he returned with a large collection. 

 During his vacations in Spain, in 1902 and 1905, he obtained many 

 similar fossil mammals from Concud, in Aragon, while in 1908 and 

 1910, in the same country, he collected rare Jurassic fishes in the 

 Province of Lerida, and visited the well-known painted caves near 

 Santander. 



Among Dr. Woodward's papers, other than those on fossil fishes, 

 which resulted from these various journeys, may be specially 

 mentioned those on the fossil reptiles and certain mammalian 

 remains from South America, which he published with the co- 

 operation of Dr. Francisco P. Moreno, founder of the Museum of 

 La Plata. He described and interpreted a new Mesozoic crocodile, 

 Notosuchus, from the Cretaceous of JS'euquen, Patagonia, related to the 

 crocodiles from the English Purbeck Beds; also one of the most 

 primitive known snakes, Dinilysia, from the same formation. In the 

 same district were found the remarkable skull and other remains of 

 Miolania argentine/,, which he compared in detail with the similar 

 extinct horned tortoises from Queensland and Lord Howe's Island, 

 and discussed in connexion with the theory of a former antarctic 

 continent, connecting Australia and South America. He concluded 

 that the discovery of Miolania did not necessarily support the theory 

 because it was related to a practically cosmopolitan Jurassic group of 

 Chelonia. Among later fossils he prepared for the Zoological Society 

 in 1899 and 1900 the first detailed account of the dried skin and 

 associated bones of the Ground Sloth, Grypotherium listai, which 

 excited so much interest and speculation when they were found in 

 the Eberhardt cave at Last Hope Inlet, Southern Chile. His 

 interpretation of the original piece of skin proved to be correct 

 when the skull and other bones of the animal were subsequently 

 discovered. 



Dr. Woodward's other papers on the higher vertebrates include 

 several accounts of British fossils. In 1905 he described Mr. Alfred 

 Leeds' discovery of the limbs and tail of Cetiosaurus leedsi from the 

 Oxford Clay of Peterborough, and showed that this Dinosaur 

 resembled the American Diplodocus in having a long lash at the end 

 of its tail. In 1910, when describing Mr. P. L. Bradley's discovery 

 of a skull of Megalosaurus in the Great Oolite of Minchinhampton, he 

 pointed out that this Dinosaur also agreed with its American repre- 

 sentative, Ceratosaurus, in the possession of a horn on the nose. In 

 1907 he made known Mr. "William Taylor's remarkable discovery 

 of a dwarf leaping Dinosaur, Scleromochlus taylori, in the Triassic 

 Sandstone of 'Elgin, and in the same year he published the first 

 exhaustive description of the Triassic Rhynchocephalian, Rhyncho- 

 saurus, in the Report of the British Association. Among mammals, 

 his first important paper was on the discovery of the Saiga Antelope 

 in the Thames gravels at Twickenham in 1890. In 1891 and 1912
