Show 1879.] DR. GUNTHER ON N E W SPECIES OF CHAMELEON. 149 Dorsal crest very low ; anterior part of the throat and the abdomen with a very low crest, formed by a double series of short conical tubercles. The occipital flaps are covered by large flat rounded scutes, much larger than those of the temple, which is crossed by an indistinct raised ridge running parallel to the occipital ridge. Sides of the throat with very indistinct longitudinal wrinkles. Body and^ limbs finely granular, with scattered somewhat larger tubercles. Heel without prominence. Greyish or yellowish ; occipital flaps whitish ; snout blackish. A single male, 9f inches long, of which the tail takes 6 inches. CHAMCELEON GULARIS, sp. nov. (Plate XII. fig. B.) Allied to C. brevicornis. Snout of the female not produced. The raised canthus rostralis passes uninterruptedly into the superciliary and occipital ridge, and is covered with a series of enlarged prominent reddish tubercles. Upper surface of the occipital region flat, without prominent median crest. Occiput pointed behind, but not produced into a spine ; on each side a broad flap, the two flaps being separated from each other by a deep notch. Dorsal crest very low ; anterior part of the throat with some isolated pointed tubercles in the median line ; abdomen with a low median crest. The basal portion of the occipital flap covered with small flat tubercles, the marginal half with larger ones, of which two or three are conspicuous by their very large size. Temple crossed by a raised curved ridge. Sides of the throat with two or three longitudinal wrinkles, the bottom of which is extremely finely granular, and which are separated by rows of larger tubercles. Sides of the body and legs with numerous very conspicuous larger tubercles between the smaller ones. Heel without prominence. Yellowish, sides of the body and snout black ; canthus rostralis purplish red. A single adult female, 8| inches long, of which the tail takes 4\ inches. CHAMELEON GLOBIFER, sp. nov. (Plate XIII.) Allied to C. parsonii and C. pardalis. Each canthus rostralis terminates (in the male) in an erect globular protuberance in front; behind, it passes uninterruptedly into the superciliary and lateral occipital ridge ; the occipital region being flat (without projecting median ridge), slanting from behind forwards, and with an obtusely rounded margin behind. No occipital flap. The spinous processes of the vertebral column form a crest, which, however, shows no denticulation, and but an indistinct serration immediately behind the head. Throat and abdomen without median crest. The sides of the body are uniformly finely granular ; but the dorsal crest is covered with larger quadrangular scutes arranged in vertical series, some of which descend into the fine granulation of the side of the body. The legs, loins, and sides of the throat with numerous round flat tubercles interspersed between the fine granules ; also the skin of the cheek is similarly covered. Temple very rough with |
