His chief object of research was the embryology of the 

 crocodile, in pursuit of which he collected two hundred and ten 

 eggs from nine nests, obtaining embryos of all stages. 



He also undertook the study of six Tegu eggs found in a 

 termites nest, together with the adults. 



Clifford Pope worked on the fish life of the vicinity and ob- 

 tained extensive and valuable data on thirty-five species. He 

 will continue this work during the coming season. 



Isabel Cooper made two hundred and forty-five paintings and 

 drawings in full color of fish, amphibians, reptiles and inverte- 

 brates, most of them known heretofore only from colorless alco- 

 holic specimens. 



Summary. — The expedition left New York on the S. S. 

 "Guiana" of the Quebec line on February 26th accompanied by 

 Professor and Mrs. Henry Fairfield Osborn who however, owing 

 to uncertain steamer accomodations were compelled to return on 

 the same boat. The Station was officially closed for the present 

 winter and the expedition returned on October 12th. 



Work on Volume II of the Pheasant Monograph has occupied 

 the time of the Director for the remainder of the year. 



It is planned to leave New York early in May 1920 for an- 

 other season's work.
