^ Grus canadensis is used as a group name to cover records of Cranes of this 

 type from the Pliocene and Pleistocene, including specimens that range in size 

 from the modern Little Brown Crane to the Sandhill Crane. A small Crane 

 of uncertain identity is reported by Wetmore from the Pleistocene of Florida. 



Grus minor L. H. Miller, Univ. Calif. Publ., Bull. Dept. Geol., V, Aug., 

 1910, 446, fig. 8, from the Pleistocene of Rancho La Brea, is now considered 

 by the describer as a synonym of Grus canadensis. 



5 This specimen, from either Pliocene or Pleistocene deposits, is the basis of 

 Grus haydeni Marsh, Amer. Journ. Sci., ser. 2, XLIX, 1870, 214, considered 

 by Wetmore, Amer. Mus. Nov., 302, Feb. 29, 1928, 4, as a synonym of Grus
