 Observations 071 certain Fossils from the Collection of the Academy 

 of Natural Sciences of Philadelphia, 

 By Richard Owen, Esq., F. R. S., &c. &c. 



[The organic remains which form the subject of the following paper by 

 Prof. Owen, are apart of the series collected by James Hamilton Couper, 

 Esq., during the excavation of the Brunswick Canal, near Darien, in Geor- 

 gia. Prof. Owen, having expressed a wish to examine these fossils, they 

 were transmitted to him through Mr. Charles Lyell, by authority of the Aca- 

 demy, and the following highly interesting memoir was promptly returned. 

 Besides the references by Prof. Owen to Dr. Harlan's original paper in the 

 American Journal of Science, some valuable remarks by Mr. Couper him- 

 self, will be found in volume I. of these Proceedings, page 216.] 



Genus Bos. 



No. 1. Distal half of right humerus: it is about one-sixth less 

 than the same part in Bos primogenius, and more resembles that of 

 the Aurochs : it belongs, probably, to a species of Bison. 



No. 2. The left tibia of the same species. 



Genus Equus. 

 No. 3. Fragments of a lower molar tooth of the size of the Equus 

 cahcllus : but the specific character not determinable. 



Genus Mastodon. 



No. 4. A portion of tusk, labelled Hippopotamus, but satisfacto- 

 rily known to have belonged to a Proboscidian Pachyderm by the 

 decussating curved lines, intercepting lozenged -shaped spaces, at 

 the transverse fractures of the ivory at the two ends. (The struc- 

 ture is shown in British Fossil Mammalia, p. 291, fig. 101, c.)
