•with a Revision of the Species of Chameleons. 2i 3 



Eyebrows arched ; occiput lunate, obliquely crested ; the face 

 between the front of the eyes and the tip of the nose extended 

 into two long lanceolate lobes ; scales flat, quadrangular, rather 

 large; scales of the head, especially those of the forehead, lobes 

 and occiput, larger, hexangular; edge of the eyebrows, occi- 

 pital crest, and back of the neck denticulated; the scales on 

 the side of the belly united into a group so as to form an irre- 

 gular whitish band on each side. 



Chamceleon Parsonii, Cuvier. 

 Superciliis arcuatis ; occipite oblique jnaxime cristato, facie 

 ante oculos in lobos duos breves compressos serratos pro- 

 ducto; squamis parvis quadrangularis, congregatis, capitis 

 majoribus sexangularibus.

Eyebrows arched ; the occiput obliquely expanded over the 

 back of the neck, above flat ; the front of the head over the 

 nostrils expanded into two short compressed serrated lobes ; 

 scales of the head large and hexangular, smooth, those of 

 the body small quadrangular, separated by the wrinkles into 

 ovate groups, back not crested with a central row of larger 

 scales. 



This species is easily known from the former by the large 



size of the occipital crest, and by the dentated nasal processes. 



My late friend Dr. Kuhl, in his Beitruge zur Zoologie has 



described two other species, which I have only casually seen 



in the French Museum. 



1. Chamcdeo Tigris. 



Obscurus, rufescens, totus maculis nigris adspersus, labiis 

 albescentibus ; corpus gracile, capite parvo, lineis tubercu- 

 lorum duabus pone oculos in unam medianam parum eleva- 

 lam confluentibus; frontali utrintjue cum occipitali confluen- 

 tibus.
