38. Phrynosoma coronatum (Blainville) 



This lizard was not found to be particularly abundant and 

 was collected in only a few localities : Todos Santos, Pesca- 

 dero, San Jose del Cabo, Miraflores, Agua Caliente, Triunfo, 

 and San Pedro. Eleven specimens in all were taken. One of 

 these (C. A. S. No. 46832) was secured at Triunfo in the sandy 

 bottom of a small arroyo as it was standing near the mouth of 

 an ants' nest. The native name is Chameleon. 



The femoral pores in eleven specimens vary from fifteen to 

 twenty-three; being 15 three times, 16 three times, 17 six times, 

 18 four times, 19 four times, and 23 twice. 



39. Phrynosoma blainvillii blainvillii (Gray) 



Four specimens (Nos. 4694-4697) were collected at Ense- 

 nada, April 30 and May 1, 1903. 



42. Gerrhonotus multicarinatus (Blainville) 



Owing to the difficulty of reaching the higher altitudes in 

 the mountain ranges of the Cape Region, only six specimens of 

 this lizard were collected. These were found at an elevation of 

 5400 feet in the Sierra Laguna. One was found under a dead 

 Yucca stalk, three under fallen pine trees, and two were running 

 about the grass in a mountain meadow. They probably are 

 not rare, but the cool weather and daily thunder showers at 

 this time of year (the middle of August) kept them under 

 cover. 



47. Cnemidophorus maximus Cope 



This lizard was collected at La Paz, San Pedro, Triunfo, San 

 Antonio, San Bartolo, Buena Vista, Agua Caliente, Miraflores, 

 San Jose del Cabo, Cabo San Lucas, Todos Santos, and 

 Guamuchil Rancho about twenty-five miles north of Cabo San 

 Lucas. It was one of the common lizards of the lower levels, 

 but was not seen at a greater elevation than at Guamuchil 

 Rancho, 1800 feet. Its movements were extremely swift and 

 on several occasions individuals were seen to lift the front 

 legs clear of the ground and hold the body at a slight angle 

 while running. Not always relying on brush for shelter, they
