whose death in the very noonday of his glorious 

 career as a fossil hunter cast a gloom over the world 

 of paleontology, purchased this specimen from me 

 for the Carnegie Museum. It has been described 

 in the Memoirs of the Carnegie Museum by Dr. G. 

 R. Wieland, the authority on extinct turtles, under 

 the title " The Osteology of Protostega" He says, 

 on page 289 : " The third of a century which elapsed 

 since Cope's discovery of Protostega gigas, has not 

 sufficed to bring forth a complete restoration of any 

 single individual of these great sea-turtles. How 

 welcome then has been the discovery during the last 

 two years by Mr. Charles Sternberg in the Niobrara 

 Cretaceous of western Kansas, of the nearly com- 

 plete specimens of Protostega gigas which permit 

 the present description of the organization of the 

 limbs, the most important of the parts yet un- 

 described as well as the very least likely to be re- 

 covered in complete form." (Fig. 21.) 



This rare fossil was briefly mentioned by Pro^ 

 fessor Osborn also in Science as a " complete skele- 

 ton of Protostega which lay on its dorsal surface 

 with fore limbs stretched out at right angles to the 

 median line of the carapace, measuring six feet 

 between the ungual phalanges." 



A second specimen, which I discovered and sold 

 directly to Dr. W. J. Holland, the director of the 

 Carnegie Museum, is thus described by Dr. Wieland
