222 THE AMERICAN MUSEUM JOURNAL 
Dr. R. Broom, the leading authority on the Permian vertebrates of 
South Africa and collecting there for this Museum, has recently announced 
the discovery of a fossil skeleton of Delphinognathus, a large and aberrantly 
specialized extinct reptile, related to the group of Theriodonts. These 
latter forms are believed to stand rather near the borderland between 
reptiles and mammals. The accession is important because there is very 
little South African material in the Museum. 
THE SEVENTEENTH CONGRESS OF AMERICANISTS in accordance with an 
adjournment taken in Buenos Aires in May reassembled in Mexico City, 
September 7 and continued its sessions until September 14. These con- 
gresses meet biennially, alternating between Europe and America. This 
meeting of the Congress in reality formed a part of the Mexican centennial 
which continued throughout the month of September. The papers. pre- 
sented dealt for the most part with various subjects concerning Mexican 
archeology and ethnology and were read by leading anthropologists. 
Europe was represented by Dr. Edward Seler, Berlin, the president of 
the Congress; Dr. Francois Heger, Vienna; Professor Capitan, Paris; and 
Professor Moguel, Madrid. From the United States there were in attend- 
ance, Drs. Dixon and Tozzer of Harvard, Dr. MacCurdy of Yale, Dr. Boas 
of Columbia, Dr. Gordon of Philadelphia, Dr. Hrdlicka of Washington, 
Professor Starr of Chicago and Mr. Stansbury Hagar of New York. Drs. 
Goddard and Spinden were delegates from the American Museum. 
Pusuiic meetings of the New York Academy of Sciences and its Affili- 
ated Societies will be held at the Museum according to the usual schedule. 
Programmes of meetings are published in the weekly Bulletin of the
