After a most careful comparison, I have not been able to discover 

 any distinction between the African and Asiatic specimens. The 

 Asiatic ones have the bands on the sides less marked ; indeed they are 

 generally absent, but in some specimens they are clearly indicated. 



I was much tempted to separate them on this ground ; but this cha- 

 racter, and the height of the occipital crest, would not hold out after 

 a rigorous examination and comparison. 



II Fitzinger,in his 'Sy sterna Reptilium,' gives the names ofC.coroman- 

 delicus to the Chameleon of India, C. a/7'icanus to that from Africa, 

 C. rimulosus to that from Egypt, and C. hispanicus to that from Spain ; 

 but these species, or presumed species, are not characterized. 



4. Chameleon auratus. B.M. 

 The scales large ; dorsal, chin, and ventral crest well developed. 



The occiput extended and rather pointed behind, covered above with 

 rather convex scales. The dorsal ridge is strongly toothed. 



In spirits, pale yellow, with many bright yellow spots, and with- 

 out any white spots or bands. 



Hab. Arabia (H. Christy). 



There is a second specimen, allied to this Chameleon, in the Mu- 

 seum collection, which differs in the occipital keel being very much 

 lower and flatter ; but in other respects they are very much alike. 

 The one with the flatter occipital keel was received from the Zoo- 

 logical Gardens, and was said to have been sent from Mexico. 



c. Occiput produced and acute behind, with a distinct central keely 

 with large hood-like occipital Jlaps, from apex to side of the 

 temple, covered with flat scales.
