deep. These burrows are usually constructed on sloping ground. 

 The eggs are placed in layers, each layer being carefully covered with 

 packed dirt. The breeding season is from April to the last of July. 



Range, north to Colorado, east to Missouri, south into Mexico. 

 Abundant in Texas. 



Colorado specimens.— University Museum: Boulder, June 23, 191 1 (135 

 mm.), E. Bethel, No. 124. As a specimen of this species escaped from cap- 

 tivity near the University campus about this time it is thought that this specimen 

 does not represent a true record for this species. Colorado State Historical and 

 Natural History Museum: Denver, 1872 (4 specimens, 80-105 nun.), J. W. 

 LaMunyon, locality uncertain; Stale Teachers' College Museum: Trinidad, A. E.

We have no specimens of this species in our collection. Professor 

 T. D. A. Cockerell reports this species from the Wet Mountain country 

 in Custer Co., Colo. The specimen which he collected there some 

 years ago was sent to Washington and the identification of Phrynosoma 

 modestum (Girard) returned. The specimen is lost and we are unable 

 to ascertain by whom it was determined. This species is included in 

 this report only as a species likely to be found in southern Colorado, 

 since it is found in northern New Mexico. We quote Cope 's descrip- 

 tion, as we have not examined specimens of it. 



Smallest of the species. Head broadly rounded; muzzle very obtuse, profile 

 descending steeply from a tranverse angle above the nostrils. Temporal regions 

 expanded, supporting a series of acuminate tubercles from below the front of the 

 orbit, of which the posterior only is distinctly a horn. It is directed posteriorly, 

 having usually the same direction and length of the occipital. One short acute 

 occipital horn on each side; no interoccipital. Posterior superciliary plate angu-
