observation, five in number, there are but four. Professors Baird and Girard state that in some 
specimens of Cnemidophorus tigris u four longitudinal yellow stripes may be seen extending from 
the occiput to the tail, and occasionally a little distance on the latter. In the young state, the 
black patches predominate, unite and form, as it were, the ground color, and the yellow con¬ 
stitutes irregular small spots .”—(Vide Stansbury’s Report, Appendix C, page 339.) 
The total length of Say’s Ameiva tesselata is 1 foot, tail, 8^ inches—in this respect corre¬ 
sponding with the above, but none of the specimens present the tesselated appearance described 
by Say, the “tranverse lines dividing the whole surface in a tesselated manner.”
