promise for the recovery of the nearly complete skeleton that lay 

 buried beneath the surface. However, it was a prospect, and as such 

 must be developed. I first commenced by uncovering the right femur 

 already mentioned as standing vertically in the beds with the proximal 

 end uppermost. On account of its length and the vertical position of 

 this bone it became necessary to remove considerable quantities of the 

 surrounding clay in order to give room to work advantageously. Dur- 

 ing the progress of this operation the right tibia and fibula and por- 

 tions of the pes were encountered. Then, as the work was extended 

 in order to take up these, the bones of the opposite hind leg and foot 

 were found while the development of these in like manner led to the 

 discovery of the scapulae, fore limbs and feet, and a jumbled up mess 

 of vertebrae and ribs, which, though mingled together in the utmost 

 confusion, were in a splendid state of preservation, so that when care- 

 fully separated and brought together each was seen to fall very readily 

 into its proper place in the articulated skeleton. By careful work in 

 the field all the bones of the entire skeleton were recovered save the 

 skull, atlas, axis, and third cervical, which had entirely weathered 

 away, as had also the proximal portion of the right ulna and the 

 greater portions of the first and third lumbars, which were only reprcr 

 sented by parts of their centra. Of the other bones all were recov- 

 ered except the manubrium, the second and some three or four of the 

 posterior caudals, and a few of the less important tarsal bones, pha- 

 langes and sesamoids. The right ilium and ulna, several of the ribs 

 and a few of the vertebrae were somewhat injured by surface Aveather- 

 ing and had to be partially restored in plaster after the same bones 

 from the opposite side, or, as in the case of the vertebras, from the 

 opposite sides of the same bone. The missing cervicals were replaced 

 in the mounted skeleton by actual bones from a second individual of 

 approximately the same size and proportions, while the skull is taken 

 from a third and decidedly smaller skeleton, as is shown by a com- 

 parison of the associated bones common to each, and as will readily 

 appear from an examination of the accompanying plates. This skull 

 is only placed temporarily with the present skeleton and will be re- 

 placed by another of more appropriate size and proportions when such 

 shall have been procured. 



The missing sternal, caudals and foot bones mentioned above were 

 modeled in plaster from others in our collections. These are indi- 

 cated in the articulated skeleton by a red cross, while such portions
