NEW GENERA AND SPECIES OF SNAKES 



BY AFRANIO AMARAL 

 of the Instituto de Butantan, Sao Paulo, Brazil, and of the Museu Paulista 



During the course of my studies principally of Brazilian 

 snakes I have found two new genera and fourteen new species. 

 I am describing them in anticipation of a more extended dis- 

 cussion of these forms in connection with monographs now in 

 preparation. 



I wish very heartily to thank Dr. Leonhard Stejneger for the 

 opportunity to study the American pit vipers in the United 

 States National Museum and the staff of the Museum of Com- 

 parative Zoology for hospitality during the past year.
