No. 238. MOODIE, ROY L. The Coal Measures Amphibia of North America. 

 Quarto, x+222 pages, 26 plates, 43 figures. Published 1916. Price $5.50. 



A complete account of the anatomy, distribution, classification, and relation- 

 ships of the oldest known land vertebrates of North America is given so far as 

 may be determined from the material which has been discovered. It is accom- 

 panied by a bibliography of 645 titles, which are citations to all the studies made 

 to December 1915, on the fossil Amphibia of the world. Especial emphasis is 

 laid on the anatomical facts. Plates and text figures show the osteology, the 

 lateral-line system, the dermal covering, the alimentary canal, and such other 

 features as are possible of ascertainment from the fragmentary material. The 

 history of the classification of the fossil Amphibia is given, together with an ac- 

 count of the discovery of the land vertebrates in the Coal Measures of North 

 America. Discussions of the manner of occurrence and the geological and geo- 

 graphical distribution are accompanied by maps and photographs. A large share of 

 the volume is devoted to careful description and classification of the 90 species 

 which are now known to occur in the Coal Measures of North America, with 

 figures, reconstructions, location of type material, synonymy, and references to 

 the original descriptions.
