AxoLis 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 ; 

 npper head- scales rugose, not keeled ; scales on frontal ridges and 

 supraorbital semicircles large, the latter in contact on the inter- 

 orbital region ; three large supraoculars, forming together a disk 

 sepai'ated 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, iiTCgular, 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 lamella? under phalanges 

 II 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 ; 

 belly white ; gular appendage bright red. 



Total length 225 millim. Fore limb 37 millim. 



Head 20 „ Hind limb ... 63 „ 



Width of head... 12 „ Tail 145 „

This very distinct and handsomely marked Anolis is represented 

 by a single male specimen, from Tierra Colorada, South Guerrero. 



AxoLis 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 ; 

 npper 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 

 or separated from them by one series of small scales ; occipital 

 larger than the ear-opening, sepaiuted from the supraorbitals by 

 one or two series of scales ; canthus rostralis sharp ; canthal scales
