160 THE HERPETOLOGY OF CUBA. 



posteriorly it forms a distinct superciliaiy ridge to over the hinder third of the 

 eye; loreal rows, five; subocular semicircles not very distinct, composed of 

 enlarged but rather weakly keeled scales, in contact with supralabials ; eight 

 supralabials, the posterior two weakly keeled, the sixth mider the centre of the 

 eye; temporals granular, those of the central temporal area smallest, a faintly 

 indicated supratemporal line; scales of back and sides minute and granular, 

 about four middorsal rows shghtly enlarged, weakly keeled and slightly imbri- 

 cating; ventrals larger but not very large, smooth, cycloid, and imbricating; 

 scales of anterior aspects of fore and hind Umbs enlarged, keeled and imbricating ; 

 body short and compressed, a well-developed nuchal but scarcely a trace of a 

 dorsal fold; hmbs rather long, the adpressed hind hmb reaches to between 

 eye and nostril; about fifteen lamellae under phalanges II and III of fourth toe; 

 digital dilatations well developed; tail rather long, strongly compressed; a 

 fold along the top of the tail has a slight tendency toward a "fin" (in old males 

 the "fin" may be well developed but it does not appear to be invariably equally 

 high) ; tail with evident verticils, limiting rows separated by about eight scales 

 on upper part of side of tail and by only about four or five on the lower part 

 of the side; postanal scales not distinctly enlarged. 



Colour (in fife) : — Varying shades of brown or blackish with or without 

 dorsal rhomboid markings, the rhombs often becoming confluent and fomfing 

 a Ught middorsal zone; throat with a mesh of gray lines, lower surfaces fight 

 brown or ochraceous; dewlap enormously developed (as in A. bremeri) with a 

 rich carmine spot upon a brilhant yellow ground. 



Dimensions: — Total length 166 mm. 



Tip of snout to vent 62 mm. 



Vent to tip of tail 104 mm. 



Width of head 10.5 mm. 



Fore leg 29 mm. 



Hind leg 51 .5 mm. 



This species was discussed at some length as A. angustirostris Hallowell 

 (Barbour, Mem. M. C. Z., 1914, 44, p. 292). The discovery later of Hallowell's 

 type made it clear that the name should be appfied to a totally different species. 

 This Uzard, which is a common woodland species throughout most of the Province 

 of Oriente, has probably been seen and caught by most collectors in Cuba but 

 mistaken variously for A. sagrei, A. homolechis, and perhaps other species. It 

 is usually dark brown or black when at rest and may ordinarily be foimd resting
