Several specimens from Caylloma and Sumbay, 11,300 to 
13,600 feet. 
This species is very nearly related to L. multrformis, Cope, 
from which it is to be distinguished by the larger dorsal 
scales. ‘The two species establish a passage from Liolemus 
to Ctenoblepharis, especially through C. Jamesii, Blgr. 
Liocephalus rhodogaster. 
Upper head-scales small, faintly pluricarinate; nostril 
supero-lateral ; nasal separated from the rostral by one series 
of scales; three or four supraoculars feebly enlarged trans- 
versely; parietals broken up; no distinct denticulation on 
anterior border of ear. Sides of neck slightly plicate, 
covered with small imbricate scales ; a strong fold in front of 
the shoulder. A feeble but very distinct dorsal crest. 
Dorsal scales rather small, mucronate, strongly keeled, the 
keels forming slightly oblique longitudinal lines; lateral 
scales a little smaller, strongly keeled, the keels forming 
oblique lines directed upwards; ventral scales quite as large 
as dorsals, smooth ; 73 or 75 scales round the middle of the 
body. Gular scales as large as dorsals. ‘he hind limb, 
stretched forwards, reaches the eye. ‘l'ail feebly compressed,
