SKELETON OF CAMPTOSAURUS NANUS. 



The small skeleton shown in plates 59 and 60 was in 1894 briefly 

 described ^ by Prof. O. C. Marsh as the type of a new species, and 

 later a more detailed account ^ of this specimen was given by the 

 writer. 



The elements preserved are as follows: 



Ajcis intercentrum, axis, 7 cervical, 16 dorsal, 4 sacral, and 34 

 caudal vertebrae, 1 cervical and numerous thoracic ribs, right fore- 

 limb (scapula, coracoid, humerus, radius, and ulna), 2 femora, 2 

 tibiae, left fibula, 2 ilia, 2 ischia, portion of left pubis, 2 metacarpals, 

 1 carpal, and parts of ossified tendons. 



The specimen was collected by Mr. W. H. Reed from ''quarry 13" 

 in 1882.
