Show 556 DR. A. GtJNTHER ON REPTILES AND [Nov. 1, narrowed in front, nearly twice as long as the eye, and longer than the distance between the eye and the small ear-opening. Rostral broad; nostril opposite to the suture between the rostral and first labial ; upper labials seven or eight; mental broad, but not extending backwards to the posterior margins of the first pair of lower labials, which are separated from each other by a pair of small scutes. Digits and toes very unequal, free ; tbe first digit and toe very short, but provided with a claw. Seven prseanal pores disposed in a chevron-shaped line. Tail with a median series of enlarged scutes below. Brown, above marbled with darker ; sides of the thorax with alternate yellow and black spots ; white below, throat with three or four concentric V"ghaped blue lines, the angles being directed backwards. Length of body and head 38 millim. „ head 9 „ Tail mutilated. One specimen. CHAMELEON ISABELLINUS. (Plate XXXIII. fig. 2.) This species belongs to the dilepis-gvoup of the genus, being distinguished by the large scutes of the occipital flaps and of the occiput. Casque slightly raised posteriorly ; parietal crest low, but distinct; distance between the commissure of the mouth and the extremity of the casque considerably longer than the length of the mouth ; lateral crest very distinct, Interorbital space rather concave. Occipital lobes large, elongate, covered with flat scutes in three longitudinal series; also the scutes on the crown are flat, not tubercular. Granules of the body homogeneous; a dorsal and gular-ventral crest. Tail at least as long as the body. Of an isabelline colour, with a white straight band from the axil towards the groin, and with a similar shorter, interrupted band above it. Total length 6| in. Length of tail 3| in. Distance of end of snout from end of parietal crest 1 in. Width of interorbital space 41 lines. RHAMPHOLEON PLATYCEPS. (Plate XXXIV. fig. 1.) Beside the additional cusp on each claw, neither the fingers nor the toes are provided with a spine. Body finely granular, with scattered slightly enlarged tubercles. The upper side of the head and the interorbital space are flat, granular, with a transverse series of somewhat larger granules crossing the interorbital space, and another crossing the temple ; another starts from each side of the crown, and converging and meeting its fellow behind the occiput at a very acute angle is lost on the back ; pairs of very small tubercles are placed at regular distances along the vertebral line. Tail (lost by accident) was proDably as long as or perhaps shorter than that of |
