EXTINCT VERTEBRATES*

 curator of the newly-created department of Comparative Anat- 

 omy, with Mr. S. H. Chubb as assistant.

Museum has lost one of the ablest and most prom- 

 ising of its illustration staff. Mr. Christman was in the prime 

 of life and had been connected with this department since boy- 

 hood. Gifted, hard working, painstaking, loyal and unselfish in 

 official and personal relations, he was cordially liked and much 

 respected by all his associates. 



The Snake Creek fossil quarries in western Nebraska were 



worked during the summer by a party in charge of Albert 



Thomson. A large collection was secured, mostly 



* e , fragmentary, but containing a series of fifteen 



skulls of Carnivora, three-toed horses, camels, 



ruminants, etc., a crocodile skull and several shells of turtles, 



besides great numbers of jaws, teeth and bones of some forty 



to fifty different kinds of animals, several of them new to 



science. 



Associate Curator Granger left for China in May to join the 

 Third Asiatic Expedition as palaeontologist. His reports indi- 

 cate that up to the end of the year he has been chiefly busied in 

 organization and reconnaissance work. These preliminary prob- 

 lems are especially difficult in China, where there has been very 

 little geologic survey work, the usual prerequisite for systematic 

 fossil collecting. During the coming season this requirement 

 will be partly filled by the attachment of Professor Berkey as 

 geologist to the staff of the expedition. 



Associate Curator Barnum Brown rejoined the staff of the 

 Museum in August and has been engaged upon reconnaissance 

 work in Greece, Asia Minor and India, as a preliminary to 



* Under the Department of Vertebrate Palaeontology (see also page 213).
