212 Mr. GY&ys Description of a nexo Genus of Saurian Reptiles : 



Eyebrows crested, occiput depressed pyramidical with a 

 broad lobe on each side behind ; scales large, rugose, ridges 

 on the headj back, throat and belly larger, denticulated ; the 

 scales on the top of the head and the occipital side-flaps broad, 

 hexagonal, flat and smooth. 



In the Museum is another specimen of a smaller size, which 

 agrees with the above, but the flaps on the side of the head are 

 small. It may be the other sex, or the young; it is 8 inches 

 long. 



Kuhl in his Beitrage, and Caup, in his paper in the his, 

 speaks of a Chameleon under the name of C. bilohus of Leach. 

 The only one which I am aware that Dr. Leach has described 

 is the above, which certainly agrees with Merrem's descrip- 

 tion, but not with his references. 



Chameleon Senegalensis. 

 Superciliis cristatis denticulatis ; occipite piano, postice con- 

 vexiusculo; squamis parvis uniformibus granulatis, capitis 

 paulo majoribus ovatis planis ; nucha, gula, abdomineque den- 

 ticulatis.

Inhab. '■ ? 



Length 8 inches ; body 4, tail 4. 



Eyebrows crested, denticulated ; occiput flat, behind rather 

 convex, not denticulated, bony; scales small, uniform, granu- 

 lar; scales of the head rather larger, ovate, flat; back of the 

 neck, throat and belly, denticulated. 



The three bony processes of the occiput converge, but they 

 do not unite together at their tips, as may be seen by the larger 

 scales with which they are covered. 



Chameleon hifurcus, Brong. 



Superciliis arcuatis, occipite lunato oblique cristato, facie 

 ante oculos in lobos duos lanceolatos producto; squamis planis, 

 quadrangularibus capitis majoribus sexangularibus superciliis, 

 crista occipitali nuchaque denticulatis.
