TWENTY-SECOND ANNUAL REPORT 49 



at the Zoological Park. It is entitled "In the Days of the Bison 

 Millions," and depicts a herd of perhaps 250,000 bison quietly 

 feeding on a rolling prairie covered with buffalo grass and sage 

 brush in northwestern Wyoming with the Wind River Moun- 

 tains in the background. The scene depicted would date back 

 something over half a century. 



Another new painting depicts the rapidly disappearing Cali- 

 fornia condor, the largest North American bird of prey. The 

 picture is by R. Bruce Horsfall, and shows a gorge in the Sierras 

 painted from studies made on the spot. The bird is life-size, 

 and the canvas measures sixty by seventy-five inches. 



A number of paintings showing the color changes in trop- 

 ical fishes at the Aquarium have been prepared for publication 

 by the Zoological Society. Mr. H. B. Tschudy has illustrated 

 five species, each exhibiting three to eight color phases. Mr. H. 

 Murayama has illustrated eight species, with three to four color 

 phases of each. Mr. Richard Deckert has illustrated two spe- 

 cies, with three color phases of each. Mr. L. L. Mowbray has 

 illustrated one species showing four phases of color.
