SYSTEMATIC ACCOUNT OF THE SPECIES. 143 
nuchal and anterior dorsal fold, capable, however, of more extended voluntary 
elevation in life; limbs medium short, digits well dilated, the adpressed hind 
limb reaches to the posterior border of the orbit; about sixteen lamellae under 
phalanges II and III of the fourth toe; tail rather long, strongly compressed 
with very indistinct verticils, separated by about five rows of scales; the limit- 
ing rows but slightly enlarged; no ‘fin’ upon tail; postanal scales slightly 
enlarged. 
Colour (in life): — Very varied in the fully adults, usually black or brown 
more or less uniform, pale below; the dewlap skin brick-red with black seales 
and a yellow margin. In young lizards there is generally either a light band 
along the back or a series of more or less distinct separated or confluent pale 
rhombic markings. 
Dimensions: — Total length 165 mm. 
Tip of snout to vent 61 mm. 
Vent to tip of tail 104 mm. 
Width of head 10.5 mm. 
Fore limb 25.5 mm. 
Hind limb - 46 mm. 
In this species as well as the two following the males have a markedly 
developed, erectile nuchal fold which is extended simultaneously with the 
expansion of the dewlap. 
This is the common lizard of the roadside fences and garden walls. It is 
excessively abundant, one of the commonest lizards in the world where it occurs. 
It is usually found in the lowlands and it is very rare or entirely absent in the 
more thickly forested areas. It is found all over Cuba but far more abundantly 
in the Provinces of Havana and Pinar del Rio than elsewhere for here cultiva- 
tion has cleared the face of the countryside more than in the less densely popu- 
lated Provinces of Camaguey and Oriente. 
Anolis sagrei occurs upon the hot dry coastal plain near Kingston, Jamaica, 
whence the U. 8. N. M. has received specimens some of which are now in the 
M. C. Z. The senior author did not find it when collecting about Kingston 
in 1909 and it may have been accidentally introduced. It is recorded by Boul- 
enger from Belize and Caracas but these records are very unlikely and the 
specimens should be compared with topotypes from Cuba. In ease they are 
the same further collecting is needed to show that we have not to deal with 
mistakes in labeling. The Belize record is possible but improbable, the Caracas 
record seemingly wholly impossible.
