 45967) San Pedro (45961, 45968, 45969), Triunfo (45962, 

 45963, 45970, 45971), San Bartolo (45964, 45972), Agua 

 Caliente (45973-45975), Miraflores (45976), San Jose del

61. Salvadora hexalepis (Cope) 



This species was next in abundance to Natrix and Coluber. 

 It inhabited the same kind of country as Coluber and was found 

 from sea level at La Paz to over 900 feet at Triunfo. Of the 

 ten specimens taken none gave an opportunity to discover their 

 food. They were active throughout the day, being found out 

 during the heat of the day as well as during the cooler hours. 

 One specimen (No. 45954) was taken just about noon time 

 in a brush thicket. Both the light and dark phases were found. 

 Fallen cactus trees and brush thickets were good places to find 

 this species. The natives call it Culebra sorda.
