Hurter — Reptiles an Batrachians found in St. Louis. 259

found under the detached barks of trees and under decaying logs.

28. Humeces Fasciatus. (Linn.) The Blue Tailed Lizard or ‘ Scorpion.’’ 
n abundant and very variable lizar . The young have five yellowish 
streaks on the back, and the tail is of a bright es color; in older speci- 
mens the stripes are very faint, often wanting; and in the spring the head 
of the old males becomes of a eoppery red. On one occasion I brought 
home a female of this species which I transferred to my Vivarium, where in 
a short time it deposited its eggs, six in number, in a small cavity in the 
sand under a rock. Whenever I lifted the rock, I found the lizard coiled 
around its eggs, which made it appear as if she was hatching them. Indue 
time all the eggs were hatched, and I had six nice small blue-tailed lizards, 
quite different in color from the old female. On account of not being able 
to procure the proper food for them, they soon died.
