VI. Note of the Colours displayed hy a Species of Chameleon belong- 
ing to the Genus Lophosaura of Dr J. E. Gray. By John Alex, 
Smith, M.D. (Specimen exhibited.) 
The chameleon exhibited belongs to the genus Lopho- 
saura of Dr Gray's Synopsis of the Chameleonidce, published 
in the " Annals and Magazine of Natural History," vol. xv. 
1865. The genus is distinguished by having a series of 
elongated skinny processes covered with scales, which run 
backwards from below the chin and throat ; in this species, 
the whole length of the base of lower jaw. 
It is apparently the L. ventralis {?) of Dr Gray, but the 
characters of the species are necessarily not very minutely 
detailed. 
It was much emaciated in appearance, and was allowed 
to dry considerably before putting it into spirits, and the 
brilliancy of the colours are still retained to a considerable 
extent. They are certainly strikingly different from the 
usual dingy bluish grey or dirty white which generally 
characterises all the specimens of the chameleons preserved 
in spirits. 
The whole upper surface of head is concave, and covered 
with tubercles, and the projecting occiput has a central ridge, 
and is narrow and rather pointedc Two patches of flattened 
scales lie behind the orbit, on sides of occiput and temples, 
and are divided by a ridge running back from the orbit. 
Its occipital crest is relatively more abruptly prominent 
and higher than the Lophosaura ventralis figured in the 
monograph already referred to. 
The back is denticulated along its ridge, and there is a 
series or belt of rather pointed, closely-set scales, varying in 
size, running along each side of the central line, and this is 
continued in a similar way along the whole upper half of the 
tail ; the toothed ridge disappearing towards its extremity. 
Three or four series of larger rounded scales run somewhat 
parallel to one another along the sides of the body, the largest 
series running backwards from behind the shoulder to the 
root of the tail. A belt of larger sized light- coloured scales
