In this paper the author endeavors to trace the redistrij)ution of Life 

 in that part of North America which was covered with glacial ice. The 

 first migration was by the arctic types, which pushed up against the 

 border of the retreating ice; second by the subarctic life, following close 

 upon the heels of the arctic, and the third the temperate, the last mi- 

 gration, represented by the fornis now found in Ohio, Indiana and Illin- 

 oia. Only the third class are typically American. The northward mi- 

 grations were marked not by river course.'-! so much as by forest and 

 plains regions. We welcome this paper as throwing lightui)onthe post- 

 glacial origin of our flora and fauna. L. J. 



Southeastern United States as a Center of Geographical 

 Distribution of Flora and Fauna. By Charles C. Adams. Re- 

 printed from Biological Bulletin, Vol. Ill, No. 3, July, 1902. Pages 

 116 131. 



The author here shows that so far as the eastern United States is 

 concerned, the post-glacial life has been distributed from the southeast, 

 except the distinctly boreal forms, and still remains as a center of dis- 

 persal. He recognizes, also, a southwestern center of dispersal in the 

 arid region of northern Mexico and the southwestern United States. L J
