SYSTEMATIC ACCOUNT OF THE SPECIES. 161 



head downward upon the trunks of large forest trees. It has, like homokchis, 

 the curious habit of convulsively curUng and imcurling 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 brilUant 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 beUeve to be this 

 species in the neighbourhood of Mayari and Nipe Bay while collecting there 

 for the M.C.Z. inl915. Thus its distribution is general where there are forests 

 in the Province of Oriente.

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 semicircles ; 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 disc composed of about six large and a few additional smaller but some- 

 what enlarged scales ; these are all veiy feebly keeled and arranged m gradation, 

 the largest scales nearest the scales of the semicircles, which they equal in size; 

 there are about three series of enlarged scutes in the discs; disc separated from 

 semicircles by one row of granules; thi-ee or four scales between the super-
