Six supraocular scales ; one row between supraorbitals ; muzzle 

 elongate ; six iuterrugal rows ; median dorsals small, weakly 



keeled ; ear opening large A, roderiguesi. 



cc. Not continued to canthal series. 

 About twelve supraoculars, of which three are largest ; three 

 rows between supraorbitals ; muzzle longer ; nine interrugal 



rows ; median dorsals smooth ; ear large A. trochilus. 



Six principal supraoculars ; one or two rows between supra- 

 orbitals ; six rows interrugals ; muzzle short ; median dorsals 



small, weakly keeled ; ear large A. aureolus. 



" Fifteen supraoculars ; one or two rows between supraorbitals ; 



ear small, less than occipital plate." (Bocourt) A. guentherii. 



Twelve supraoculars ; one row between supraorbitals, six rows 



of interrugals ; ear large ; muzzle short A. bransfordii. 



"Eight to ten keeled supraoculars; one row between supraor- 

 bitals ; one interrugal row ; ear opening small, less than 

 occipital scale ; scales of front and muzzle tricarinate". . .A. baecatiis. 

 aa. Supraorbital scales in contact medially.

 opening small, much less than occipital plate." (Bocourt) 



A. boumerii. 

 Of the Anolis aureolus the Smithsonian Institution possesses four speci- 

 mens from Yucatan, obtained by Arthur Schott, and tM'o specimens from 

 Guatemala sent by Henry Hague. 



Color above golden gray ; below (in alchohol) light golden yellow. 

 The females are tinged with brown above, and have a trace of a yellowish 

 dorsal band. In two of the males there are three small black quadrangu- 

 lar spots on the middle line of the nape and back separated by wide 

 spaces. 



Akolis quaggxjltts, sp. nov. 



Belonging to the section of the genus with round tail and keeled ven- 

 tral scales. 



There are seven rows of truncate and keeled dorsal scales, which are 

 much larger than the ventrals, or the granular laterals, from which they 

 are abruptly distinguished. Muzzle short and narrowed. Supraorbital 

 series separated by three rows of keeled scales, and continued well on 

 muzzle, but not to the canthus rostralis. They are separated on the muz- 

 zle by four rows of polygonal, nearly smooth scales. Facial rugae obso- 

 lete ; facial concavity shallow. The supraocular disc consists of two 

 principal large longitudinal median scuta, surrounded by seven or eight 

 smaller ones. Occipital scale little larger than those by which it is sur- 

 rounded, two of which separated it from the supraorbitals. Auricular 

 meatus much larger. Five rows of loreal, and one row of suborbital 

 scales. Tibia shorter than head. Infralabials very narrow, keeled. When 

 the posterior limb is extended forwards the end of the longest toe marks
