An account of the proceedings of one of the parties of the Wheeler 

 Expedition of 1874, to which the writer was attached as palaiontolo- 

 gist. The most important discovery made was that of a great series of 

 lacustrine beds corresponding with the lowest fossiliferous beds of Wyo- 

 ming, and containing an abundant Mammalian fauna. These beds cover 

 an area of about 3000 square miles between the Chama and San Juan 

 rivers, are L. Eocene, and contain the remains of Vertebrata, many 

 being new. H. A. N.
