Of the vertebrate texts in use there are several, any- 

 one of which covers special portions of the field exception- 

 ally well. Karl A. von Zittel's, Die Grundzuge der Paldon- 

 tologie, however, is the only reliable general and comprehen- 

 sive work. The English translation of the vertebrate sec- 

 tion of Zittel by Charles R. Eastman has been completed 

 and published through the fishes, amphibians, reptiles and 

 birds, but the volume on the mammals has not yet appeared. 

 Professor Wiiliston's "Water Reptiles of the Past and 

 Present" is a splendid and up-to-date work in the special 

 field of reptiles, as is this same author's American Permian 

 Vertebrates. Dr. Osborn's The Age of Mammals, and 

 Professor Scott's A History of Land Mammals in the 

 Western Hemisphere are both excellent and thoroughly 

 systematic texts. A readable, though not very up to date 

 text is : Henry A. Nicholson and Richard Lydekker's A 

 Manual of Paleontology, volume 2, London, 1889. Other 

 good German works are O. Abel's, Grundzuge der Palae- 

 obiologie der Wirbeltiere ; Guztave Steinmann's Elemente 

 der Paldontologie and K. H. Stromer's Lehrbuch der Pald- 

 zoologie, Part I, Wirbellose Tiere. 



The best North American collection of displayed 

 and stored vertebrate fossils is located at the American 

 Museum of Natural History in New York City. The 

 Yale University vertebrate collection now ranks second, 

 though up until the last few years, it was the largest and 

 most complete in the United States. There is a very good 

 vertebrate collection at Princeton University. An excellent 

 collection of vertebrate fossils is also to be found at the 

 National Museum in Washington, D. C. The best col- 

 lection of Permian reptiles is in the Walker Museum at the 

 University of Chicago. The Universities of Kansas and 

 of Nebraska have good vertebrate collections. The Uni- 

 versity of Wyoming has a splendid stored collection but 

 none mounted. There is a large mounted collection at the 

 University of California at Berkeley and also at the Uni- 

 versity of Toronto. A fine collection of vertebrates has 

 also been acquired by the Canadian Geological Survey 

 at Ottawa. Harvard like many other American Universi- 

 ties has practically no vertebrate collection at all. The 

 best collections of vertebrate fossils in the world are now 

 distributed throughout the United States and, for this
