 Anolis (Dracontura) alutaceus, Cope, Proc. Ac. Philad. 1801, p. 212. 



Head elongate, less so than in A. spectrum. Frontal ridges dis- 

 tinct, not elevated, convergent anteriorly, and enclosing a very- 

 elongate dej)ression ; anterior upper head-scales weakly many-keeled 

 or smooth, those of the supraorbital semicircles separated medially 

 by small scales ; five to seven enlarged supraocular scales, separated 

 by granules from the supraorbitals ; occipital small, irregular, 

 widely separated from the supraorbitals ; canthus rostralis not 

 prominent ; upper labials seven ; auricular opening moderate. 

 Gular appendage elongate, of female rudimentary. Lateral scales 

 small, gradually blending into the larger dorsals, of which there are 

 about ten rows, Aveakly keeled ; ventral scales smooth, transversely 

 oblong, in some specimens having a carinate appearance upon the 

 thoracic region. The adpressed hind limb reaches the orbit. Tail 

 cylindrical, a little more than twice the length of head and body. 

 Upper parts dark cinnamon, lighter in the female, beneath paler, 

 thickly punctulated with brown on the throat, sides, and extremities; 

 on the head, a light band crosses the anterior part of the supra- 

 orbital region, and another extends longitudinally back from the 

 rostral plate. 



Total length 134 millim., head to ear 15, tail 01.

Head nearly twice as long as broad, as long as or slightly longer 

 than the tibia ; snout acuminate ; forehead concave, frontal ridges 

 obsolete ; upper head-scales strongly bi- or tricarinate ; scales of 

 the supraorbital semicircles slightly enlarged, separated by two or 

 three series of scales ; six or seven strongly enlarged, pluricarinate 

 supraocular scales, separated from the supraorbitals by one series of 

 smaller scales ; occipital as large as the ear-opening, separated from 

 the supraorbitals by three or four scries of scales ; canthus rostralis 

 distinct, cauthal scales four ; lorcal rows seven ; eight labials to 

 below the centre of the eje ; ear-opening rather large, vertically 

 oval. Gular appendage large, extending posteriorly beyond the 

 thorax, indicated in the female ; gular scales keeled. Body a little 

 compressed ; no dorso-nuchal fold. Dorsal scales large, hexagonal, 

 juxtaposed, strongly keeled, in eleven longitudinal series ; lateral 

 scales minutely granular ; ventral scales larger than dorsals, rounded, 

 imbricate, strongly keeled. Limbs slender ; the adpressed hind 

 limb reaches the anterior border of the orbit or the nostril ; digits 

 very feebly dilated ; thirteen or fourteen lamellae under phalanges 

 n. and iii. of the fourth toe. Tail roundish, slightly compressed, 

 covered with equal, strongly keeled scales ; its length not twice that 

 of head and body. No enlarged postanal scales. Tale brown above; 

 a broad dark brown band from the eye to the side of the body : limbs
