ON THE REPTILIA OF PERU. 



except at the orbit, where there are two. Postocular and temporal scales equal to 

 or larger than the dorsal. A series of large infralabials in contact with the labials 

 throughout. Auricle half the size of the eye-slit. The legs are short ; the fore 

 foot only reaching to the front of the orbit, and the hind limb falling considerably 

 short of the axilla. Toe expansions rather narrow. Lateral occipital crests 

 prominent. 



Color above dark gray, below pigmented white (in spirits). The two colors 

 are abruptly denned between the orbit and the scapula, and there are brown spots 

 behind the axilla. Tail distantly annulate.

From between Moyabamba and Balsa Puerto, on the river Huallaga in Eastern 

 Peru. 



Besides its generic characters, this species has larger head scales than the A. 

 gracilis, where the superciliaries are separated by two series. The legs are shorter.

From Nauta. 



Mr. O'Shaughnessy has recently (Annals Magaz. Nat. Hist. 1875) regarded 

 the A. impetigosus, Cope, as identical with the present species. I think that it 

 will be found on examination of the type specimen now in the British Museum, to 

 differ from the A. transversalis in its larger abdominal scales, larger and fewer 

 supraorbitals, less numerous large inferior caudals, and strikingly in the coloration. 



A few other determinations of Mr. O'Shaughnessy's paper will require revi- 

 sion. Thus the specimen in the British Museum labelled Chamaeleolis porcus is 

 not the species described by me under that name ; the only specimen of it known 

 to me, is in the museum of the Philadelphia Academy. Anolis argenteolus and A. 

 lucius are distinct. The A. chlorocyaneus, of Dum. Bibr., includes two species, as 

 their description indicates, and as I discovered by an examination of the type
