Liolaemus alticolor sp. nov. 
Plate 5, upper figure. 
Types,— two specimens, no. 7287, Museum of Comparative Zodlogy, 
from near Tiaguanaco, Bolivia, altitude about 13,100 feet; T. Barbour, 
collector. 
Nostrils lateral. Upper head-seales rather small, smooth, somewhat 
convex; a small frontal; interparietal smaller than parietals; two or 
' three greatly enlarged supraoculars; a single series of scales between the 
supralabials and the infraocular; temporal scales slightly swollen but 
smooth; anterior border of ear with one or two very small projecting scales. 
Sides of neck with a few granular scales, not conspicuously folded. Dorsal 
scales rather large, strongly imbricate, keeled, mucronate; lateral scales 
smaller; ventrals smaller than dorsals, rounded, smooth; fifty to fifty- 
four scales around middle of body. The adpressed hind limb reaches to 
between shoulder and ear. Hinder side of thighs granular. Male with 
three preanal pores. 
Color complicated in pattern. Above with longitudinal lines and stripes 
of black, grayish, light and dark brown. Sides of male red, of female 
brown. Belly silvery gray. 
These specimens were caught as they ran into a very ancient 
stone wall, during a flurry of snow. No others of the species 
were seen. 
Among a number of tree frogs taken by Mr. Hay and me, while 
in Petropolis, is a specimen which does not seem referable to any 
described species; it may be known as 
Hyla hayii sp. nov.
