Ch. malthe, Giinth. Several specimens from Analamazotra. 4219-21. 
Ch. parsonsi, Cuv., cristifer, var. nov. (Plate XI, figs. 1-3). Differs 
from parsonsi in the possession of a dorsal crest on the body and an 
ill-developed parietal crest on the head. It is related also to Ch. glohifer, 
from which, however, it differs essentially in the shape of the rostral 
processes, which appear to be typical for parsonsi. Onr specimens show 
some variation in the lepidosis of the body and limbs; in most of the 
examples this lepidosis is homogeneous, but in one or two individuals a 
few somewhat enlarged tubercles are developed on the forearm. 
A common chamaeleon at Analamazotra. It reaches a considerable 
size ; the largest specimen preserved measures from tip of horns to vent 
172 mm., and from vent to tip of tail 265 mm. 4222-27. 
Ch. gastrotaenia, Blgr. Two individuals were taken at Analama- 
zotra and another at Ampantomaizina. In the specimen from the coast 
there is an incipient development of a dorsal crest, but the tubercles are 
ill-developed and ill-defined and extend but for a short distance along 
the back ; the lepidosis of the body is composed only of flattened scales ; 
in the Analamazotra specimens small granules occur between the scales. 
4228-30. 
Chamaeleon chauvini, sp. nov. (Plate XI, fig. 4). This species is closely 
related to Ch. furcifer, and just possibly it may eventually prove to be a 
juvenile form of that species. 
The casque is low, being practically continuous with the dorsal crest. 
Occipital lobes are absent. The scales on the head are small and subequal. 
There is no parietal crest. Three or four tubercles slightly larger than 
the scales which surround them indicate a very feeble dorso-lateral crest 
on both sides of the casque. The temporal crest is feebly developed ; 
the lateral crest is continued in front into a bony rostral process which is 
short, slightly concave above, and bifid at the end ; this rostral process 
projects about 1 mm. beyond the upper lip. There is present a dorsal 
crest of small compressed tubercles extending to a point just above the 
knee when the hind limb is placed in line with the body. No gular nor 
ventral crests ; lepidosis of body, limbs, and tail homogeneous ; scales 
granulated. 
From tip of snout to vent the measurement is 56-5 mm. The tail 
is 56 mm. long. 
A double white line extends along the throat and ventral surface of 
the body ; just before the vent it is interrupted as it passes up and down 
the hind limbs, to continue its course behind the vent for a distance about 
equal to one-third of the length of the tail. 
A faint light lateral line containing two white spots is also visible. 
One specimen, a collected by M. Herschell-Chauvin near Tamatave. 
4237. 
Ch. bifidus, Bronquiart. An adult male from Ampantomaizina, and 
an immature male from the forest of Chambaena (?), a day and a half 
distant from Tamatave (Herschell-Chauvin). 4231-32. 
Ch. nasutus, D. and B. Several specimens near the coast at Ambilo 
and in the “ jardins d’essai ” near Tamatave. The colour of this animal 
in life is reddish-brown. 4233-36.
