Rep. d'Eg. pl. v, f. 3, 4; the adult, Daucl. III, xlv, 1, under the name of Orbiculaire, is a little animal whose body is also sometimes inflated, and remarkable for changing its colours even more suddenly than the Chameleon. When young it is entirely smooth; there are some larger scales scattered among the small ones on the body of the adult.( 1) LEIOLEPis, Cuv. The teeth of an Agama, the head less inflated, and completely covered with very small, smooth, and compact scales. Pores on the thighs.(2) The TnoPIDOLErxs, Cuv. Still similat· to the Agam~ in teeth and form, but regulal'ly covered with imbricated and carinated scales. The femot·al pores are stt·ongly marked.(3) The LEroso:r.lA, Spix-TnoPmosAunus, Boie, Only differs ft·om Tropidolepis, by· having no pores.( 4) CALOTEs, Cuv.(5) Tbe Calotes differ from the Agam::e in being regularly covered (1) lt.is difficult to establish precise limits between this subgenus and certain short, tluck Agam;e, that have but few spines. (2) There is a ~pecies in Cochin China that is blue, with white stripes ~uvl spots, al)d a long tatl (Leil. guttatus. Cuv. ). (3) .!lg. urufulata, Daucl., a species that is founcl throughout America, remaJ·k-able ~ot· a ';lut~ cross under the throat, on a bbck-blne ground. The .9g. nigri-collarzs, ~ptx, XVI, 2, and c,yclurus, XVIII, f. 1, arc at least closely allied to it. . (4) Sptx has not e_XJ_>resscd himself with precision in saying that the scales of hts lepoTso ma 'adr e verltctllate, and this it is which has de·c eived M. ."cLt• 't zm· gc1.. Tl1 e ge~us . ~·opt osam·us was made by Boie from a small species from Cochin China wluch ts m the Cabinet du Uoi. ' (5) Pliny says that the Stellio of the Latins was called by the Greeks Galeotes, Co~otes, and . .!lslralabotes. It was, as we have seen, the Geclcotte of Lacep. Its application by_Lmn;eus. to his Lac. calotes is arbitrary, and was suggested to him by Seba. Sptx com~rtses our Calotes in his genus LOPHYRUR, which is not the same as that of Dumertl. SAURIA. 29 with scales, arranged like tiles, frequently carinated and terminating in a point on the body as well as the limbs and tail, which is very long; those on the middle of the back are more or less turned up, and compressed into spines forming a crest of variable extent. They have no visible pores on the thighs, which, added to their teeth, distinguishes them ft·om the Iguan~. The most common species, Lac. calotes, L.; Seb. I, lxxxix, 2; xciii, 2; xcv, 3 and 4; Daud., III, xliii; .!lgama ophiomachus, Merr., is of a pretty light blue with transverse white streaks on the sides; there are two rows of spines behind the ear. From the East Indies. It is called a Chameleon in the Moluccas, although it docs not change its colours. The eggs are fusiform. ( 1) In the LorHYRus, Dumeril, The scales on the body are similar to those of the Agamre; there is also a crest of palisado-like scales still higher than that of the Calotes. The tail is compressed and the femoral pores are wanting. A remarkable species is, .figama gigantea,(2) Kuhl; Seb. I, c. 2, whose dorsal crest is placed very high on the neck, and is formed of several rows of vertical scales; two bony ridges, one on each side, extend from the muzzle to the eye, where they terminate in a point, and join (1) Add the ./lg. gutturosa, Merr. or c1istatella, Kuhl; blue, without bands, and small scales on the back; Seb., I, lxxxix, 1 ;-the .!lg. cristata, Mcrr., Seb. I, xciii, 4, amlll, lxxvi, 5, a reddish brown, with blackish brown scattered spots, of which the Jlgame arlequine, Daucl. III, xliv, is the young;-the .!lg. vultuosa, Ilarl. l>hil. Ae. Nat. Sc.lV, xix. • All these species are from the East Indies; the Lopltyrus ocl11'ocolla1·is and margaritaceus, Spix, XII, 2, are American Calotcs; the first is the same as the .!lgama picta, Pr. Max.; the Loplt. panthem, Spix, pl. xxiii, f . .1, is the young of the same. Add to these American Calotes Loplt. rlwmuifer, Spix, xi, of which the Loph. alUomaxillaris, Id., XXIli, f. 2, is the yonng;-Loplt. am·onitens, Spix, pl. xiii. 'Ve might separate from the other Calotes ~species ft•om Cochin China, with a smooth back, without any visible scales; the belly, limbs and tail covered with carinated scales (Cal.lepidogasler, Nob.); the .!lg. cr;denala, l'r. Max. liv. V, may belong to this group . N.B. The designer of Seba's plates has given to most of his Iguanre, Agam:-c, .Calotcs, &c. extensible and forked tongues, drawn from imagination. (2) It is difficult to imagine the reason that induced Kuhl to c::Lll this Saurian gigantic, as it is not larger than its most closely allied Agamre and Calotes. • From the observations of Major Le Coutc, it would seem that what is here called the .!lg. mdtuosa is the young of anotllCI" species. .!lm.
