Order Lacertilia. 
The local Lizards, which number two species, are so different 
in general aspect that immediate identification is possible even 
to the novice. The smooth, shining Blue-tailed Lizard and the 
rough, somber-tinted Fence Swift are the examples. The oc- 
currence of the latter species is rare within the limits embraced 
by this list. Both species are very active, and are insectivorous 
in habits.
