Lac. africana, Gm.; CamSlSon ordinaire^ Lacep., I, xxii; Seb. 

 I, Ixxxii, 1, IxXxiii, 4.(1) (The Common Chameleon.) The 

 hood pointed and relieved by a ridge in front; the granules on 

 the skin equal and close; the superior crest indented as far as 

 half the length of the back, the inferior to the anus. The hood 

 of the female does not project so much and the denticulations of 

 her crests are smaller. From Egypt, Barbary, and even the 

 south of Spain, and India. 



Cham, tigris, Cuv. Another similar species from the Se- 

 chelles with a hood resembling that on the female of the pre- 

 ceding; the granules on the skin fine and equal; it is distin- 

 guished by a denticulated and compressed appendage under the 

 extremity of its lower jaw. The body is sprinkled with black 

 points. 



Cham, verrucosus^ CuV. A third neighbouring species from 

 the island of Bourbon, marked by granules larger than the 

 others which are scattered among them, and by a series of 

 Avarts, parallel to the back at about two thirds of its heights. 

 The hood is like that on the female of the common one; the 

 -notches on the back are deeper, those on the belly the reverse. 



Cham, pumilus, Daud. IV, liii; Lacerta pumila, Gm.; Cham, 

 margaritaceus, Merr; Seb. Ixxxii, 4, 5. The hood directed back- 

 vv^ards; warts scattered on the flanks, limbs and tail; numerous, 

 compressed, finely notched appendages (lambeaux) under the 

 throat, which vary in each individual. Found at the Cape, Isle 

 of France and the Sechlles.(2) 



Ch. planiceps, Merr., Seb. I, Ixxxiii, 2; Laccrta chamselion, 

 Gm. The hood flattened, and almost destitute of a ridge; its 

 figure is a horizontal parabola. Found in Senegal, Barbary, and 

 even in Georgia. 



Ch. pardalis, Cuv, The hood flat like that of the Senegal spe- 

 cies; but there is a little prominent edge to its muzzle, in front 

 of the mouth; larger granules scattered among the smaller ones, 

 and the body irregularly marked with round black spots, edged 

 with white. From the isle of France. 



Ch. Parsonic Cuv. Phil. Trans. LVIII. Another species, with 

 a flat hood, which is slightly truncated behind; crest of the eye-
