AMERICAN SOCIETY OF ZOOLOGISTS. I. 



The American Morphological Society 

 and the Zoologists of the Central and 

 Western States met in Washington, D. C, 

 in the Medical School Building of the Co- 

 lumbian University, December 30, 1902, 

 and held joint sessions during this and the 

 two succeeding days. A very large num- 

 ber of the members of the societies were 

 in attendance, and an unusually long and 

 interesting program was enjoyed. 



During the meeting final action was 

 taken that brought the members of the two 

 above-mentioned societies together under 

 the name of the American Society of Zo- 

 ologists, with an eastern and a central 

 branch. The constitution adopted looks 

 toward meetings of the society once in 

 three years, to be held alternately in the 

 territories of the two branches. The time 

 and place of the annual meeting of each 

 branch is to be determined by its executive 

 committee. 



During the afternoon of the first day a 

 joint session was held with Section P of the 

 American Association for the Advancement 

 of Science, at which papers from the pro- 

 grams of each of the societies were given. 

 Owing to the large number of papers to 

 be presented, further combination did not 

 seem expedient. 



The following are brief abstracts of the 

 papers that were presented:
