124 CLASS REPTILIA. 



There is at the Cape a smaller agama, with mode- 

 rate tail, varied with brown and yellowish, and hav- 

 ing all the upper part bristling with raised and 

 pointed scales. {.Ag. Aculeatea^ Merrem. Seb. I. viii. 

 6, Ixxxiii. 1 & 2, cix. 6). Its belly sometimes has 

 an inflated form.* 



Agam-s: Orbicularijl. Daud. in part. 



Which are only agamse ; those with the inflated belly 

 have the tail short and slender. Such is 



The Tayapaxin of Mexico. Hern. 327- Lac. 

 orhiculai'is. L. 



With spiny back and belly sown with blackish 

 points.t 



cclxxiii. 2, which is an anolis, Edw. ccxlv. 2, which is also an anolis, and 

 this same figure is again cited by him and Gmelin under the Polychrus. 

 Shaw even copies it to represent the Polychrus, with which it has 

 nothing in common. Seb. I. cvii. 5, which is the true Ag. Colononim of 

 Daud., is quoted by Merrem under Ag. Superdliosa ; and Seb. I. cix. 6, 

 which is his Aculeata, is cited under Orbicularis, Src. 



* The Agame a Pierreries, Daud. IV. 410. Seb. I. viii. 6, is but the 

 young of this spinous agama, more varied in colours than the adult. 

 Add, Ag. Atra, Daud. III. 549, rough, blackish, with a yellowish line along 

 the back ; — Ag. Umbra, Daud., which is not the Lac. Umbra of Linnaeus, 

 but is distinguished by five lines of very small spines predominating on 

 the back. 



•]- I do not think that this subgenus can be preserved. The species just 

 named does not appear to me to differ from the Agama Cornuta of Harlan. 

 Annat. sc. Phil. IV. pi. xlv. except, perhaps, in sex. Daudin has reprinted 

 it in its place. III. pi. xlv. f. 1. The adult is our Trapelus of Egypt.
