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.

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 lucius; 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-hke 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 sUghtly enlarged scales, 

 continued posteriorly it forms a weak supercihary 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 &,spects of limbs
