GROUND LIZARD. 651 
not contiguous. Length, 74 inches; fore limbs, 1; head to axilla, 14; body, from 
muzzle to anus, 3; hind limbs, 18; tail, 43; diameter of head, 3; diameter of body, 4. 
Habitat, Massachusetts, New York, to Georgia, Florida, and Mississippi, north to 
Ohio, Michigan, and Illinois. 
In the young the yellow stripes are very distinct, and disappear with 
age, a8 well as other marks of coloration, which, taken with a slight varia- 
tion in the cephalic plates, would lead one to suspect a distinct species. 
The female also probably differs from the male by the retention of the 
characteristics of the young longer, it may be to an adult state. 
The blue color of its tail may be due to its having been broken off and 
reproduced, but it is probably its natural tint. 
The Blue-tailed Skink is found under bark in May; it is very active in 
its movements and difficult to capture. It lays nine oval eggs ata time; 
is occasionally seen sunning itself, and when alarmed makes a rapid 
retreat.
