This varied character of the waters, taken into account with the 

 number of prominent rivers, results in an unusually large number 

 of species. The subject has been investigated by many authors, 

 so that the list here given may be regarded as very nearly complete. 

 The volume gives for each species the technical name and original 

 describer, the popular names and a concise description ; then fol- 

 lows a general account as to distribution, habits, economic value, 

 and so on. The volume is liberally illustrated, both by text- 

 figures and by excellent full-page plates, many of the latter show- 

 ing the species in their natural colors. 



9. W-iedersheinx's Comparative Anatomy of Vertebrates / 

 adapted from the German by W. N. Parker. Third Edition, 

 pp. vi, 576 ; with 372 figures. London, 1907 (Macmillan & 

 Co.). — For a quarter of a century the German editions of this 

 work have served as standard books of reference throughout the 

 world. The two preceding English editions have been used 

 extensively in advanced courses in vertebrate anatomy in the 

 principal universities of all English-speaking countries. The 

 present book, based on the sixth German edition, has been almost 

 entirely re-written by Professor Parker and such additional mat- 

 ter and illustrations added as were necessary to include the 

 results of the most recent investigations in the field of vertebrate 

 zoology. The more important original publications on the sub- 

 ject are arranged in a classified bibliography containing more 

 than two thousand titles. 



As a standard text-book for advanced students, and a reference 

 handbook for teachers and students in elementary courses, this 

 work stands preeminent. It is, however, to be regretted that 

 so excellent a book is marred by a large number of typographical 

 errors. w. R. c. 



10. Final Natural History Mssays / by Graham Renshaw. 

 Pp. 225. London and Manchester, 1907 (Sherratt & Hughes). — 

 This book consists of a series of essays on some of those species 

 of mammals which are of peculiar interest to the general reader 

 either because of their singular habits and instincts or their near 

 approach to extinction. The subject is treated from the stand- 

 point both of the zoologist and the historian, and a multitude 

 of interesting facts about the animals selected are presented in a 

 popular and entertaining manner. w. r. c.

1. Report of the Secretary of the Smithsonian Institution for 

 the Year ending June SO, 1907. Pp.95. Washington, 1907. — 

 The report of the Secretary of the Smithsonian Institution 

 recently published is of special interest since it is the first which 

 has been issued by Dr. Walcott. The Institution is fortunate in 

 that its new head has not only a thorough command of the various 

 branches of science concerned, but also has unusual executive
