82. Crotalus exsul Garman 



Our collections include four specimens of this rattlesnake. 

 Three of these were collected by Mr. R. H. Beck near Ense- 

 nada, February 27 \ 1908. The fourth (No. 42047) was 

 brought back by the "Albatross" from Turtle Bay, Lower Cali- 

 fornia. The scale-counts are given below. 



84. Crotalus enyo Cope 



This species was the most abundant of the rattlesnakes en- 

 countered. Like the gopher-snakes they were mostly confined 

 to the vicinity of habitations. As in other places, rattlesnakes 

 were found in the early morning or evening. One specimen 

 (No. 45884) was found early in the morning coiled up under 

 a pile of brush. Another (No. 45886) was found coming out 

 of a rock wall within a few feet of a house. Their food con- 

 sisted of small mammals, as far as discovered from specimens 

 collected. The natives call all rattlesnakes by the name Vivora. 

 Specimens were collected at Miraflores (45879), San Antonio 

 (45880), Todos Santos (45881), San Bartolo (45882), San 

 Pedro (45883, 45884), San Jose del Cabo (45885), and in the 

 Sierra Laguna (45886).
