140 THE HERPETOLOGY OF CUBA. 
cephalus. The distribution of A. lucius is rather limited. Gundlach found it 
at Matanzas and the San Miguel hills near Coliseo, and it has been taken also at 
Madruga and near Aguacate (Barbour). Barnum Brown collected an example 
now in the M. C. Z., in the Sierra de Jatibonico in Santa Clara. The species 
extends much farther eastward than we had previously supposed, for it has 
been taken near Cienfuegos, at Guaos, in February 1917 (Barbour) and Rodri- 
guez has sent us a typical example from Guaimaro, in the Province of Camaguey.

Lagartija; Lagartijo de Tablado, (Santiago). 
Diagnosis: — A slender, long limbed, long tailed, ashy gray Anolis, having 
a very large eye and a flat almost spatulate rostrum. 
Description: — Adult @ M. C. Z. 7,488. Cuba: Santiago, The Plaza, 
1909. Thomas Barbour. 
Related to Anolis lucius from which it may be easily distinguished by its 
form and colouration. It is much more slender, having a head twice as long 
as broad, instead of one and one half times as in luctus; the snout much more 
depressed; the white occipital spot and the conspicuous white head-band and 
the brown chevrons are wanting in argenteolus. 
Top of head with two slightly developed ridges, enclosing, however, a 
sharply depressed oval area; head-scales smooth or feebly keeled; about eight 
scales in a row between the nostrils; supraocular semicircles very broadly in 
contact, the whole median part of each semicircle being composed of a pair of 
great plate-like scales; supraocular semicircles consisting of six or seven flat 
scales; barely separated from the semicircles by a row of minute granules; 
occipital as large as ear opening and in contact with the semicircles; canthus 
rostralis scarcely indicated, consisting of four or five slightly enlarged scales, 
continued posteriorly it forms a weak superciliary ridge to above the centre of 
the eye; loreal rows, seven; subocular semicircles of elongate strongly keeled 
scales broadly in contact with supralabials; seven smooth supralabials, the 
suture between the sixth and seventh about under the centre of the eye; tem- 
porals minute; a very indistinctly defined supratemporal line; whole of back 
and sides covered with minute flat scales, almost granular; ventral scales 
larger, squarish or rotund, non-imbricating; scales on anterior aspects of limbs
