large blue or green area along each side of the body is 

 crossed by two almost vertical black blotches, behind which 

 there usually is a small round black spot. The limbs are 

 crossed by bands of dusky. The females have the larger 

 markings on the upper surfaces more distinct than the males,

 spot of the males, and often have a large bright cad- 

 mium orange spot behind the axilla.

Remarks. — This species is of smaller size than C. ven- 

 tralis. The difference in the lateral black blotches in the 

 males is very constant as is also the color and shape of 

 the upper caudal cross-bars. It is most closely related to 

 C. d. carmenensis, and some specimens from La Paz show 

 intergradation with that subspecies. It is like C. d. carmen- 

 ens'is in the coloring of its back and tail but differs in the 

 number and arrangements of its black lateroventral blotches. 



'Distribution. — This species was first described from a 

 specimen collected by Botta in "California." It has since 

 been found at La Paz, San Jose del Cabo, Cape San Lucas, 

 Sierra San Lazaro, Miraflores, Agua Caliente, Buena Vista, 

 San Bartolo, San Antonio, Triunfo, and San Pedro, all in 

 the Cape Region or San Lucan Fauna of Lower California. 

 Here it is a common species, especially near the sea-coast in
