MEXICAN Miocene 



From Mexico, Bosef has described several small faunas 

 from the Isthmus of Tehuautepec, and from the States of 

 Oaxaca and Vera Cruz. These faunas, he considered as Upper 

 Miocene and Pliocene. 



The most interesting of these localities, in the present con- 

 nection, are those at Tuxtepec in the State of Oaxaca, and 

 Santa Rosa and the Barranca de Santa Maria Tatetla in the State 

 of Vera Cruz. From these localities, we may note together 

 with their Costa Rican and other affinities, the following 

 species:
