24 LACERTILIA. 
One of the commonest and most generally distributed species of Central America, 
extending southwards into Venezuela and Ecuador. 
Very common in woods about the Isthmus of Tehuantepec (Sumichrast) ; common 
at Duefias, Coban, and Lanquin, in Guatemala (Salvin).

Ameiva festivus, Bocourt, Miss. Sc. Mex., Rept. p. 260, t. 20 a. fig. 10, and t. 20 p. fig. 3. 
Hab. Guatemata, lower forests of Vera Paz (Salvin), Rio de la Pasion, Rio Polochic; 
Costa Rica (Cope); Panama, Veragua (Ler/. MJus.). 
Abdominal scutes in eight longitudinal series; three large przeanals, one in front of 
the two others. A patch of enlarged scales occupies the middle of the throat, and is 
surrounded by very small scales. Supraorbitals three. Anterior margin of the collar 
covered with large scales. Nostril between two scutes. Humeral scutes in one series, 
separated by a granular interspace from the pectoral scutes. 
‘This species is scarcer and less generally distributed than A. undulata, and extends 
southwards into Colombia (Cope). 
5. Ameiva quadrilineata. 
Cnemidophorus quadrilineatus, Hallowell, Proc. Ac. N. Sc. Philad. 1860, p. 488. 
Ameiva quadrilineata, Cope, Proc. Ac. N. Sc. Philad. 1862, p. 61. 
Hab. Nicaracva (Hallowell). 
Abdominal scutes in eight longitudinal series; the praanals disposed in a single 
series, the posterior being the largest. A patch of enlarged scales occupies the middle 
of the throat ; they are numerous, and graduate into the smaller ones. Supraorbitals 
three, sometimes a minute posterior fourth. Collar bordered by two series of enlarged 
scales. Humeral scutes in one main series. “Two narrow yellow lines on each side ; 
the superior from the superciliary margin, convergent on the nuchal region, the inferior 
from the orbit, interrupted by the femur, continued on the base of the tail, bounded 
above and beneath by black. Inferior lateral region black, greenish vermiculated. 
Back posteriorly varied with black.” 
A. quadrilineata was founded upon young specimens, the bodies of which are only 16 
lines long; and Bocourt is quite right in regarding the species as a very doubtful one 
(Miss. Sc. Mex., Rept. p. 295); he himself notices, under the name proposed by Hallowell, 
a young specimen from Veragua, but thinks that this as well as the types may prove to 
be young A. undulata.
