primitive known four-footed animals, from the Permian of 

 Texas. 



The principal items of Mr. Chubb's work during the year 

 may be summarized as follows: "Lee Axworthy" skeleton and 

 Zebra skeleton in process of construction; Mountain Zebra skull 

 and limb bones prepared for study collection; 112 sections of 

 fossil teeth made; "Man-o'-War" album, containing 31 sepia 

 prints, presented to Mr. S. D. Riddle, owner of "Man-o'-War" ; 

 247 prints labeled, trimmed and filed; 149 prints mounted and 

 labeled in Equidae albums; tables of measurements of Equidae 

 skeletons; tables of vertebral formulae of Equidae. 



Work on the series of restorations of dinosaurs, including 

 Camarasaurus, Diplodocus, Ankylosaurus and others, has been 

 interrupted by the sad death of Mr. Erwin S. Christman, and 

 only the Camarasaurus was completed and placed on exhibition. 



The Curator, accompanied by Mr. H. C. Raven, left New 

 York on May 25th on the "First Australian Expedition." The 

 Australian objects of the expedition are: first, to secure ex- 

 Field hibition material for the proposed Australian 

 Work Hall; secondly to obtain reference and study col- 

 lections illustrating the mammals, birds, fossil vertebrates and 

 anthropology of Australia; thirdly, to bring about a closer co- 

 operation in scientific and educational work between this Museum 

 and Australian museums and other scientific centers. In all 

 these objects the expedition is meeting with considerable success, 

 owing in part to the generous cooperation and assistance of many 

 Australian colleagues and friends. 



In the mountains of Northern New South Wales the expedi- 

 tion secured excellent exhibition and study collections, including 

 kangaroos, wallabies, flying phalangers, pygmy phalangers, 

 "opossums" (Trichosurus) , and several species of small insectiv- 

 orous marsupials {Phase ogaW). Mr. Raven is now (January, 

 1922) in Queensland, where he has succeeded in securing the 

 tree-kangaroo, the koala, the rare pygmy kangaroo Hypsiprym- 

 nodon, and four genera of polyprotodonts. 



Dr. Gregory visited the principal museums and other scien- 

 tific centers in New South Wales, Queensland, Tasmania, 

 Victoria and South Australia, and made arrangements for ex- 

 tensive exchanges illustrating the anthropology, zoology and
