tions of two new genera of uncertain ordinal position as well as 

 two new genera of rodents, including in all an equal number of 

 species. In the second paper a number of creodont genera and 

 species are described, all referable to the Hysenodontidse, the last 

 surviving family of the order. r. s. l. 



9. New or little known Titanotheres from the Eocene and the 

 Oligocene ; by Henry Fairfield Osborn, Bull. Amer. Mus. 

 Nat. Hist., vol. xxiv, 1908, pp. 599-617 with 21 figures in the 

 text. 



"In the preparation of the U. S. Geological Survey monograph 

 'The Titanotheres' the collections of Eocene and Oligocene 

 materials in the larger museums of the country have been 

 reviewed with care. Like the Oligocene titanotheres previously 

 reviewed, the Eocene titanotheres prove to be in a high degree 

 polyphyletic." From the Wind River formation are two genera 

 and three species ; from the Lower Bridger one genus and three 

 species ; from the Upper Bridger and Lower Washakie three 

 genera and five species ; from the Upper Washakie and Lower 

 Uinta two genera and four species; from the Upper Uinta two 

 genera and three species, and finally from the White River 

 Oligocene two new genera, each with a single species, are 

 described. 



Dolichorinus hyognathus, of which the more familiar name, 

 Telmatotherium cornutum y is a synonym, is restored in the skele- 

 ton and gives a good idea of the appearance of one of these 

 ancestral titanotheres. r. s. l.

1. The Autobiography of Nathaniel Southgate Shaler, with 

 a supplementary Memoir by his wife. Pp. 481, with 16 illustra- 

 tions. Boston and New York, 1909 (The Houghton Mifflin 

 Company). — The six or seven thousand students who heard Shaler's 

 lectures at Harvard during his forty years service were always 

 deeply impressed with his personality, his wide experience of men 

 and the world, and his vivid presentation of the principles of geo- 

 logy, enlivened by ever-flowing narrative of pertinent incidents, all 

 the more entertaining from being phrased in picturesque language. 

 The personality of the man is strikingly presented in this volume, 

 of which the first half, descriptive of his youth up to the begin- 

 ning of the Civil War, comes from Shaler's own pencil — for it 

 was his habit to prepare manuscript with pencil rather than with 

 pen — while the second half, descriptive of his more mature years, 

 is written by his wife. The picture that we gain of the way in 

 which science was studied at Harvard under Agassiz is particu- 

 larly interesting ; a way that was well fitted for youths of the 

 strong individuality that Shaler possessed. Several chapters on 

 excursions along the coast of Maine and farther down east, with 

 Hyatt, Stimpson, Verrill and others, are of special interest as
