FALCONER ON THE AMERICAN FOSSIL ELEPHANT. 
G1 
§ A Associated Fossil Mammalia. 
Of the Mexican Mammal cotemporaries of E. Cohmbi , but very 
little has as yet been ascertained. Yon Meyer, in his notice of Herr 
Uhde’s collection, mentions a Mastodou, resembling M. angustidens of 
Kepfnach in Switzerland ; a phalangeal bone of a Pachyderm, bearing 
some resemblance to that of the genus Rhinoceros ; and upper and 
lower molars presenting the characters of the existing genus Equus* * * § 
The collection formed by M.H. de Saussure, included Mastodon Andium, 
as distinguished by the French Paleontologists from M. Himboldtii. 
In Texas,t as already stated, JE. Colimhi was found along with re¬ 
mains of Tapir us Americanus (Leidy), Bison latifrons (Leidy), a 
species of Mastodon not named; bones supposed to be of a species of 
Mylodon , and probably also a colossal form of JE. priniigenius. 
The Georgian remains from the Brunswick Canal have been 
severely examined by different paleontologists. Among them, be¬ 
sides Elephant, there were Megatherium mirabile (Leidy), Mylodon 
Harlani (Ow.), Mastodon Ohioticus, Bison latifrons (Leid.), JEguus 
Americanus (Leid.),£ together with bones of a large Chelonian, Che- 
lonia Couperi (Harlan). It was supposed, at the time of their dis¬ 
covery, that the Darien fossil Fauna, included Hippopotamus and 
Sus ; § of these the former was negatived by Prof. Owen, and the 
tusk fragment upon which it was founded referred to Mastodon, 
while the latter has passed through many phases of nomenclature. 
First named Sus Americana by Harlan (loc. eit.), it was then re¬ 
garded by Prof. Owen as the type of a new genus intermediate to 
Lophiodon and Toxodon , which he first described under the designa¬ 
tion of Lophiodon bathygnathus,\\ and afterwards as Harlan us Anieri- 
canus ; % but the specimen upon which the opinion rested has been 
satisfactorily determined by Leidy to be nothing more than a lower 
jaw of his Bison latifrons.** At Skiddaway Island on the Atlantic 
shore, near Savannah, the same genera and species have been met 
with ; and Dr. Leidy mentions the association, on the shores of the 
Ashley Fiver in South Carolina,ft of remains of the same Megatherium , 
with those of Blephas, Mastodon , Equus, Tapir us, Bicotyles, Hipparion^ 
Hydrochcerus , &c.{J On all occasions, until lately, where this Ele¬ 
phant has been named, in the American memoirs, it has been cited 
as E. primigenius. Generalising approximatively, as far as the as¬ 
certained data will admit, it would appear that where fossil Ele-
