 Anolis ortonii Cope, sp. nov. 



Of the same group as the last, that is, with smooth abdominal scales, and 

 the median series of caudal scales not larger than the lateral ; the tail is, 

 however, only partially preserved, and as it is somewhat compressed the char- 

 acter of the vertebral scales may have been different in tlie lost portion. 



Muzzle convex, wider than long, (measuring at anterior angle orbit,) covered 

 with scales of different sizes. Occiput small, separated by several rows from 

 superciliaries. Scales between tlie facial rugaj hexagonal, smooth, in four 

 longitudinal rows, a little smaller than the plates of the ruga which extend to 

 the central row. Dorsal and lateral scales granular, nearly equal, and smaller 

 than the rounded ventrals. Brachial scales a little larger, weakly keeled, anti- 

 brachials much larger, keeled. Labials 8 — 8, the two posterior very small ; 

 loreal rows six. Frontal cavity distinct ; superciliaries separated by one row 

 scales. Sides of muzzle M'ith longitudinal, smaller, weakly keeled scales. 

 Auricular meatus two-fifths length eye fissure. Infralabials longitudinal 

 smooth, in two or three rows. Supraorbital disc of some seven broad smooth 

 plates, separated from superciliaries by a row of granular scales. Gular fan 

 large. 



When the limbs are extended the end of the metacarpal reaches end of 

 muzzle, and the longest toe nearly reaches the orbit. The digital dilatations 

 are well developed. 



Top of head, nape, a rather narrow dorsal region and upper surfaces of 

 limbs Ijlackish coppery ; sides and below golden, fan deep saffron yellow.
