an author. Probably the best known publications outside of Japan are: 



Uguma, K., and Makino, S. Check-list of chromosome numbers in Vertebrata, 

 Zool. Mag. (Japan) 43:176-212. 1931. 



Oguma, K. , and Makino, S. A revised check-list of the chromosome numbers 

 in Vertebrata, Jour. Genetics, 26:239-254. 1932. 



Uguma, K., and Makino, S. A new list of the chromosome numbers in 

 Vertebrata (March 1937), Jour. Fac. Sci. Hokkaido Imp. Univ., 

 Series VI, Zoology, Vol. 5(4): 297-356. 1937. 



Students of animal science will immediately recognize the importance of 

 this chromosome list as a reference, particularly those in the fields of zoology, 

 cytology, genetics, taxonomy, evolution, and animal breeding. It has a parallel 

 in the "Chromosome Atlas of Cultivated Plants" published by C. D. Darlington 

 and E. K. Janaki-Ammal in 1945. 



This list of animal chromosome numbers represents the fulfillment of a 

 request that I made of Dr. Makino to prepare an English Language edition for 

 publication in the United States. At the time, I was on the staff of General 

 Headquarters, Supreme Commander for the Allied Powers, as Chief of the Agri- 

 culture Division of the Natural Resources Section. 



It is a privilege to recommend AN ATLAS OF THE CHROMOSOME NUMBERS IN 

 ANIMALS, second edition, to biologists everywhere.
