386 PR0CEED1N08 OF THE NATIONAL MUSEUM. vol.54. 



The other anatomical details of the skeleton of Stegosaurus have 

 been so fully covered in an earlier paper ^ that no notice of them 

 need be taken here except to mention that the digital formula of the 

 forefeet is still in doubt. Following fragmentary evidence in the 

 form of several incomplete feet in the collections, they were restored, 

 as follows: Digit I, two phalanges; digit II, three phalanges; digit 

 III, four phalanges; digit IV, three phalanges; and digit V, two 

 phalanges. Digits I and II being terminated by broad, flat, hooflike 

 unguals ; the other three digits terminated by short but transversely 

 expanded elements which in life were doubtless inclosed entirely 

 within the muscular mass of the foot, thus giving but little, if any, 

 external indication of their presence. 



The fossil bones used in this mount Avere largely prepared by 

 N. H. Boss, preparator in the section of vertebrate paleontology, 

 who also niodeled manj'^ of the missing parts. The actual mounting 

 of the skeleton is the work of Thomas J. Home, preparator in the 

 same section, who is to be highly commended for the skill displayed 

 in overcoming the many difficult mechanical problems presented. 

 The inconspicuousness of the framework of iron necessary to sup- 

 port these fragile, though heavy bones shows for itself the highly 

 filled character of the work. For the pose of the skeleton and 

 whatever anatomical discrepancies may be found I alone must be 

 held responsible. 



Many of the bones used in the mount are described and figured 

 in Bulletin 89, United States National Museum, these being indi- 

 cated in the appended list of bones used in the mount.

THE STEGOSAURUS EXHIBIT IN THE UNITED STATES NATIONAL 



MUSEUM. 



In 1904 a natural size life restoration of Stegosaums stenwps 

 Marsh (see pi. 62), formed a part of the United States National 

 Museum exhibit at the World's Fair held in St. Louis during that 

 year. At the close of the fair it was returned to Washington and 

 there made a part of the exhibition series of the Section of Verte- 



« Gllmore, C. W., Bull. 89, U. S. Nat. Mus., 1914.
