COUES AND YARROW ON HERPETOLOGY. 287 



BafracMa, these animals are true Lizards, belonging to a large group 

 which contains the Iguana, and numerous well known smaller species of 

 this country. The presence of a tail, which is not found in adult life in 

 the typical Batrachians; the scaly armor of the body, as contrasted 

 with the naked skin of Batrachians 5 the mode of development, in not 

 passing through a larval Tadpole stage, in which the species breathe in 

 the water by means of gills ; and the ambulatory, not saltatorial, mode 

 of progression, are some of the prominent characteristics by which the 

 Phrynosomw show their true affinities. 



Although of rather repulsive aspect, the Horned Lizards are inof- 

 fensive and perfectly harmless animals. They are rather sluggish, 

 easily captured, make no resistance, and are readily tamed, when they 

 make rather amusing pets for those who may desire to watch their sly 

 and furtive ways. They feed principally upon flies, ants, and other small 

 insects, which they catch by rapid protrusion of their viscid tongue, 

 leaping, or rather running, at their prey sometimes. One that had been 

 tamed would eat from the fingers, and also take a drop of milk, appear- 

 ing greatly to relish it. Like other cold-blooded animals, they sustain 

 long fasts without apparent inconvenience, and may be safely mailed 

 alive, as curiosities, to almost any part of the country. We have never 

 been able to keep them alive over four months. 



The subspecies of this same P. dotiglassii {ornatissimum) is principally 

 found in the Sonorau region, but specimens are in the National Museum 

 from Utah and Upper Colorado and Pole Creek (wherever that may be).
