SYSTEMATIC ACCOUNT OF THE SPECIES. 161 
head downward upon the trunks of large forest trees. It has, like homolechis, 
the curious habit of convulsively curling and uncurling the tail when it is wounded 
or noosed; and when it is at rest the tail is almost always kept more or less 
tightly curled up. The enormously developed and brilliant dewlap often sud- 
denly expanded with a quick nodding motion of the head make a bright flash 
of colour in the sombre forests which allogus frequents. The large series now 
in the M. C. Z. are from Los Negros, Baire, Jiguani, San Luis, Pozo Prieto, 
and Monte Libano (de la Torre, Barbour, and Rodriguez); the collection of 
the junior author contains specimens from many stations about Guantanamo, 
and Sagua de Tanamo, while Mr. J. L. Peters found what we believe to be this 
species in the neighbourhood of Mayari and Nipe Bay while collecting there 
for the M. C. Z.in 1915. Thus its distribution is general where there are forests 
in the Province of Oriente.

Plate 10, fig. 3. 
Lagartija. 
Diagnosis: — A rather small but not a slender Anolis, in general appear- 
ance like the common A. sagrei, but it may be recognized at once, since it has 
a white dewlap with a large red-brown spot on its base. 
Description: —Typr. Adult M. C. Z. 11,285. Cuba: Pinar del Rio; 
Valley of Luis Lazo, March, 1915. Thomas Barbour. 
Head with two slightly diverging ridges on the frontal region; forehead 
concave; all the head-scales rather feebly keeled; seen from in front, rostral 
about the same height as the mentals; six elongate scales between the nostrils: 
a single series of scales separating the supraocular semicireles; occipital slightly 
smaller than ear opening, separated from the supraocular semicircles by about 
four rows of scales, which are very much larger than the dorsal granules and 
slightly larger than the scales which bound the occipital posteriorly; supra- 
orbital dise composed of about six large and a few additional smaller but some- 
what enlarged scales; these are all very feebly keeled and arranged in gradation, 
the largest scales nearest the scales of the semicireles, which they equal in size; 
there are about three series of enlarged scutes in the dises; dise separated from 
semicircles by one row of granules; three or four scales between the super-
