 United States National 

 Museum. The Irish elk has 

 been remounted at least three 

 times, and is noio in Hall 6. 

 This ground sloth is not the 

 Panamanian specimen 

 currently on exhibit. The 

 Zeuglodon was not collected 

 until the 1890s, so the pho- 

 tograph can be dated within 

 about a fifteen-year intenial 

 near the turn of the century.
