1879.] DR. GUNTHER ON NEW SPFXIES OF CHAMJSLEON. 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 au 

 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. 



Chameleon 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 fl;U 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, 85 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, s>hows no denticulation, and but an indistinct serration im- 

 mediately 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
