NEW ACCESSIONS TO THE EXHIBITION SERIES AT YALE MUSEUM 

 BY RICHAKD S. LULL 



The speaker exhibited on the screen photographs of two notable specimens 

 placed on exhibition in the Peabody Museum at Yale, a remarkably complete 

 skeleton of a Cotylosaurian reptile, Limnoscelis from the Permian of New 

 Mexico, together with a model described by Professor Williston and a mounted 

 skeleton of Equus scotti from the Pleistocene of Texas. 



NEW MASTODON FIND IN CONNECTICUT 

 BY EICHARD S. LULL

NOTES ON CAMAROSAURUS COPE 

 BY CHARLES C. MOCK 



The author summarized the results of his studies on the Camarosaurus 

 skeleton in the Cope collection and exhibited a photograph of the life-size 

 reconstruction made many years ago under Professor Cope's direction. The 

 skeleton is a composite representing several individuals ; the reconstruction is 

 chiefly of historic interest as the earliest attempt at restoration of the skeleton 

 of a sauropodous Dinosaur. He called attention to the upright pose of the 

 limbs. The genus Camarosaurus did not appear to be separable from Moro- 

 sauriis Marsh, which it antedated by some two months.

DINOCEPHALIANS

 specialized adaptations. Both were offshoots from the main line of reptilia 

 which led up into the primitive mammalia. 



Doctor Gregory commented on divergent views that had been entertained 

 as to the affinities of the Pelycosaurs.
