SALVADORA MEXICANA (Dumeril and Bibron) 



One specimen (No. 109234) was collected 4 km. north of Apatzingan, 

 Michoacan, on March 15, 1939. This specimen was discovered in a 

 fence formed of loose rocks, with the body concealed and a small portion 

 of the neck protruding straight up from the top of the fence, the head 

 turned toward me as I approached. The snake made no movement, and 

 it was quite by accident that I saw it. The stomach contained a Scelo- 

 ponis pyrrhocephalus and a Uta gadovi.
