Viejo (M. A. Carriker) ; Palomina (W. W. Brown). This species is dif- 

 ficult to collect, as it frequents the heavy forest and is apparently not abun- 

 dant. Only one specimen was taken as low as 4.500 feet on San Lorenzo ; 

 the others observed in this region were between 5,000 and 6.000 feet. In 

 the forest on San Lorenzo about six were observed in two months' w'ork, 

 two on the ground, the others on ferns and vines to a height of 20 feet on 

 trees. Most of the specimens taken were secured in the large quebrada of 

 Viernes Santo, in 1920, where, owing to the wadth of the stream, the forest 

 canopy is broken and there is a riparian association of low shrubs and trees. 

 In this habitat the lizard was found on the small trees and shrubs. 



Norops auratiis (Daudin). — Santa Marta to 2,200 feet, San Lorenzo; 

 Aracataca (Rehn and Hebard) ; Fundacion ; Las Pavas ; Valencia; Valle 

 de Upar; Arroyo de Arenas; Palomina and Pueblo Viejo, 8,000 feet (W. 

 W. Brown). Common in open woods and in clearings; generally found on 

 grass and low bushes ; abundant about the open marshes at Bolivar and 

 Fundacion. 



Tropvdodactylus oiica (O'Shaughnessy). — This species was only found 

 at Riohacha, and in but one place — a desert flat between the town and the 

 Rio Rancheria. It was apparently not common. All of the specimens taken 

 (17) were on the ground. It is very shy and at the slightest cause for 

 alarm dashes into a hole. 



It is to be noted that the adpressed hind limb does not reach the border 

 of the eye, as stated by Boulenger, but the posterior border of the ear. 



Polychms spurrelli Boulenger. — Aracataca (Rehn and Hebard). Taken 

 from stomach of Leptophis occidentalis. 



The specimen is referred to P. spurrelli with some doubt. It corre- 

 sponds to the description of that form and differs from P. marmoratus in 

 the scutellation of the body, but it is like the latter in having a gular 

 denticulation. 



Basilisciis barboitri Ruthven. — From Santa Marta to 2,200 feet ; Gaira ; 

 Fundacion ; Valencia ; Valle de Upar ; Loma Larga ; Palomina and La Con- 

 cepcion (W. W. Brown). Apparently common in the localities in which 

 it was found, occurring only along the streams, where it is generally found 

 on rocks, logs, etc., near the water, occasionally in bushes up to a height 

 of about twenty feet. When alarmed, individuals frequently dash across 

 the water on their hind legs, and occasionallv adopt this method of locomo- 

 tion on land. (PI. IX, fig. i.) 



Leiocephalus erythrogastcr (Hallowell). — Bolivar to 2,000 feet; Tucu- 

 rinca (Rehn and Hebard) ; Valencia. Only observed on the ground and 

 on logs and rocks in dry forests. 



The species is secretive and apparently somewhat local in distribution 

 in the localities in which it was observed. 



Iguana iguana (Linnaeus). — Santa Marta to about 600 feet. San 

 Lorenzo; Aracataca (Rehn and Hebard) ; Fundacion; Valle de Upar; San 

 Juan de Cesar; Fonseca and Arroyo de Arenas (observed) ; Riohacha. 



Where there are deep ponds or streams (<?. g., Fundacion and Valle de
