nated crest on each side, and three series of black spots along the 

 upper region of the body. The presence of but one series of supra-

OBSERV. -We are not prepared to tell whether Liolaemus bellii, 

 GRAY (Catal. Lizz. Brit. Mus. 1845, 212), L. unicolor, GRAVENH. (Nov. 

 Act. nat. cur. XVIII, ii, 1838, 728), both from Chile, belong to this 

 section or to Liodeira; they not being sufficiently described to permit 

 classification in regard to the genera or subgenera, as here circum- 

 scribed. Liolaemus elegans, TSCH. (Faun. Peruan. Herp. 1845, 33), 

 from the coast of Peru, falls into the same category.
