PALEONTOLOGY — HAY, WIELAND, WILLISTON. 24I 



Hay, 0» p., American Museum of Natural History, New York, N. Y. 



Grant No. 118 (supplement). Cof/ipletioii of a monograph on the 



Jossil turtles of North America. (For previous reports see Year 



Book No. 2, p. xxxvii, and Year Book No. 3, p. 122.) $1,800. 



During the present year the monograph has been pressed forward 

 with all possible diligence. Nearly 500 pages of manuscript have 

 been written, about 400 drawings have been made, and over 100 pho- 

 tographs have been prepared. The large number of fossil turtles col- 

 lected by the writer in the Bridger basin in 1903 have entailed a large 

 amount of work in their preparation and determination, but they have 

 added greatly to our knowledge. A considerable number of inter- 

 esting forms have been collected during the past year by the exploring 

 parties of the various museums, and it has been necessary to study 

 and figure these. It is hoped that the work will be completed within 

 the present year. 



Wieland, G« R., Yale University, New Haven, Connecticut. Grant 

 No. 243. Researches on existing and fossil cycads. (For pre- 

 vious reports see Year Book No. 2, p. xxxvii, and Year Book 

 No. 3, p. 123.) $1,500. 



Abstract oj Report. — Dr. Wieland reports that his time has been 

 mainly occupied in bringing to publication the first results of the 

 cycad investigations in the form of a quarto volume on American 

 fossil cycads (structure), and in the preliminary work for a second 

 volume of equal, if not greater, extent on American fossil cycads 

 (taxonomy). 



Williston, S. "W"., University of Chicago, Chicago, Illinois. Grant No. 



49. Preparation of a monographic study of the North American 



extinct Mesozoic reptiles. (For previous report see Year Book 



No. 2, p. xxxviii.) $800. 



Abstract of Report. — Professor Williston reports that he has been 



engaged steadily in the study of North American plesiosaurs, but on 



account of its magnitude he can not state just when the work will be 



completed. About 75 plates and a large quantity of manuscript have 



been prepared. One month of the past year was spent at Yale 



University in the study of the material in the museum there, and 



some weeks in the collection of new material in Wyoming.
