sides, the greater part of the feet and three-fourths of the terminal 

 end of the tail are bright yellow, the feet and tail being rather 

 narrowly banded with bright orange. The upper crest of the 

 body is grey, it slightly continues on the anterior greyish por- 

 tion of the tail ; the lower crest is white, and specially in front 

 very distinctly developed. The forehead is very concave and 

 the occipital crest high ; the posterior naps are not developed, 

 but the orbital ridge which begins at the rostral end is very 

 prominent, and joins the posterior end of the occipital ridge by a 

 flexuoiis curve, being slightly bent downwards behind the eye, 

 but at the same time continuous throughout. A distinctly separ- 

 ate low ridge runs from the end of the occipital crest to the upper 

 posterior end of the tympanoid region ; the scales on this ridge are 

 elongately tubercular, but not much larger than those accompanying 

 it on both sides. The scales on the gular sack are small and 

 arranged longitudinally in two rows. 



The deeply excavated forehead and the numerous cross bands 

 distinguish the present specimen as the variety called by Dr. 

 Grray marmoratics, but the author of the monograph does not 

 state where that variety was obtained ; it is certainly a peculiar 

 one, for judging from our specimen, it does not exhibit a trace of the 

 two longitudinal bands on the sides of the body, noted as character- 

 istic of the typical Ch. vulgaris of Africa and Europe. Fitzinger 

 applied the name Ch. Coromandelicus to the Indian Chamceleon, but 

 the name Ch. Ccylom'cas, Laur., used by Dr. Jerdon in his account 

 of the species has priority (J. Asiat. Soc. B., XXII, p. 466.) 



Dr. Gr ay (loc. cit.) however, says that " after rigorous examina- 

 tion and comparison," the differences existing in the European', 

 African and Asiatic forms do not possess specific value. There can 

 be no doubt that both forms are very similar and perhaps referable 

 to one species only. Setting asido coloration and conrparing 

 various specimens of the Indian Chamaleon, it is remarkable to 

 find that the posterior extension of the supraorbital ridge is always 

 very distinct in them, and the same also applies to the ridge descend- 

 ing from the posterior cud of the occipital crest downwards, whilfij 

 in the African form these ridges appear to be much loss developed]
