ON THE REPTILIA OF PERU. 



Coppery-brovra above ; below, light coppery, frequently dusted and speckled 

 with brown, especially in females. 



As compared with A. bransfordii and other allies, the A. bocourtii has a longer 

 head, fewer and smooth supraorbital scales, and shorter hind legs. It is abundant 

 at Nauta. I dedicate it to Dr. Bocourt of Paris, whose magnificent work on the 

 Eeptiles of Mexico has added much to our knowledge of the Anolidce. 



18. Anolis trachyderma, Cope, sp. nov. 



Abdominal scales small, obtusely keeled ; three or four median dorsal series, 

 nearly as large as the ventrals, flat, keeled, and quickly graduating into the granu- 

 lar scales of the sides. These, with the scales of neck, throat, and sides of the 

 head, are angulate or subround so as to produce a shagreened surface. Tail round, 

 curved with flat keeled scales. Occipital oval, small, nearly equal to ear, separated 

 by two rows of elongate keeled scales. Facial rugae obsolete, the scales on its 

 usual position and external to it, larger than those that occupy the frontal con- 

 cavity, which are narrow, keeled, and in five or six rows, arranged (in the only 

 specimen) concentrically posterior to a median scale. Twelve rows at the middle of 

 the muzzle, all. flat and carinate. Supraorbitals keeled, arranged in a circle round 

 two central scales, ten altogether. Six rows at middle of lores. Auricular meatus 

 one- third of eye. Labials 9-11 ; infralabials not distinct from gulars, keeled. 



Head oval, as long as tibia ; muzzle longer than wide at front of orbits. The 

 fore limb reaches the end of the muzzle, but the hind limb only extends to the 

 middle of the orbits. Fan large. 



Color black, above and below, excepting thorax, abdomen, and inferior middle 

 line of tail, which are fulvous. An indistinct light band across the chin, half way 

 between eye and nostril.

Abdominal scales keeled ; dorsals much smaller, smooth, and a little larger 

 than the almost granular laterals. Tail subround, with equal scales. The head
