ANOLIS GADOvII. (Plate VI. fig. 1.) 
Head once and two-thirds as long as broad, slightly longer than 
the tibia; forehead concave; frontal ridges distinct, divergent; 
upper head-scales rugose, not keeled ; scales on frontal ridges and 
supraorbital semicircles large, the latter in contact on the inter- 
orbital region; three large supracculars, forming together a disk 
separated from the supraorbital semicircle by two series of small 
scales; occipital large, a little larger than the ear-opening, 
separated from the supraorbital semicircles by two series of small 
scales; canthal scales four, loreal rows six; six or seven upper 
labials to below centre of eye; ear-opening large, vertically oval. 
Gular appendage very large, extending far back on the breast ; 
gular scales smooth. Body compressed; no dorso-nuchal fold. 
Dorsal scales small, smooth or faintly keeled, irregular, juxtaposed ; 
lateral scales minute, granular; ventral scales larger than dorsals, 
smooth, juxtaposed. The adpressed hind limb reaches the eye; 
tibia as long as the distance between the end of the snout and 
the ear; digits moderately dilated; 20 lamelle under phalanges 
TI and III of the fourth toe. Tail feebly compressed, not crested, 
once and three-fourths length of head and body. No enlarged 
postanal scales. Greyish above, with black wavy and vermicular 
lines; two parallel black lines on each side from shoulder to hip ;

This very distinct and handsomely marked Anolis is represented 
by a single male specimen, from Tierra Colorada, South Guerrero, 
ANOLIS LIOGASTER. (Plate VI. fig. 2.) 
Head once and a half as long as broad, longer than the tibia ; 
forehead deeply concave ; frontal ridges strong, short, divergent , 
upper head-scales smooth or feebly keeled; scales of the frontal 
ridges and supraorbital semicircles large, the latter in contact on the 
interorbital region or separated by one series of small scales ; three 
large, smooth or faintly keeled, transverse supraocular scales 
forming a single longitudinal series, in contact with the supraorbitals 
ov separated from them by one series of small scales; occipital 
larger than the ear-opening, separated from the supraorbitals by 
one or two series of scales; canthus rostralis sharp; canthal scales
