contact medially, or more usually separated by a series of narrow scales. Pal- 

 pebrals about six in each disc, weakly keeled. Scales of the muzzle unicari- 

 nate ; facial rugae not very prominent, much raised above the plane of the 

 canthus rostralis, enclosing a very shallow concavity. Superior labiils four 

 or five ; first pair of inferior labials (" mentals ") large ; infralabials small, 

 elongate. Goitre small. Scales of the sides granular ; scales of the belly, 

 tail, extremities and from thirteen to seventeen dorsal rows, elongate, strongly 

 carinate. Digital expansions narrow. Anterior extremity not reaching the 

 groin, the posterior reaching the middle of the orbit. Length of head and 

 body 1 in. 5 lin. ; of tail, about 2 in., (mutilated.) 



The under surfaces are yellowish, unspotted. Above, the ground color is 

 golden olivaceous in the males, in the females golden brown. There is a slight 

 median dorsal line extending to the sacral region ; another similar one extends 

 from the superior posterior part of the orbit upon the anterior part of the tail, 

 and a third from the posterior superior labials, through the tympanic orifice, 

 upon the base of the tail. The superior lateral band is bordered above by a 

 deep brown band.

This species is somewhat similar in proportions to A. p u 1 c h e 1 1 u s, D. B., 

 which it seems to connect with the Draconturce.

Dr. Hallowell's description was taken from specimens much decolorized by 

 alcohol. The only differences noticeable, on comparing with Berthold's de- 

 scription, are, that the inferior brown band does not pass along the middle of 

 the side, but on the borders of the ventral plates ; and that the central palpe- 

 bral shield is not the largest, while the whole disc is in contact with the su- 

 perciliaries, with but one or two minute scales intervening. 



Habitat. New Grenada ? Surinam. 



Anolis (Dracontura) alutaceus Cope. 



Size small, form elongate. Plates of the front and muzzle weakly many- 

 keeled or smooth, those of the superciliary ridge separated medially by small 

 scales, in number four on each side, the apterior largest and in line with two 

 or three large scales anterior to it. Occipital plate small, irregular, widely 

 separated from superciliaries ; the latter separated by granules from the five 

 to seven plated palpebral disc. Facial rugae distinct, not elevated, convergent 

 anteriorly, and enclosing a very elongate depression. Canthus rostralis straight, 

 elongate, not prominent ; nostril lateral, terminal. Rostral plate rather large, 

 its superior border curved, and of a light color. Upper labials seven ; lower, 

 nine, the first pair (mentonnieres, D. and B.) transverse, separated by a short 

 straight median suture. Goitre of female rudimentary ; of male, elongate, 

 perhaps not very extensible. Ventral plates smooth, transversely oblong, in 

 some specimens having a carinate appearance upon the thoracic region. Late- 

 ral scales small, gradually blending into the larger dorsal, of which there are 

 about ten rows, weakly keeled. Scales of the external surfaces of extremities 

 rather large, weakly one many keeled. Tail cylindrical, a little more than 

 twice the length of head and body. Posterior extremity reaching to (% ) mid- 

 dle, anterior, or ( 9 ) posterior part of orbit ; anterior extremity two-thirds the 

 distance to the groin. Auricular opening moderate. Total length of adult 

 male 5 in. 3 lin. ; tail, from vent, 3 in. 7 lin. ; head to ear 7 lin. 



Color of the adult male above, dark cinnamon brown, deeper on the head 

 and extremities ; beneath paler, thickly punctulated with brown on the throat, 

 sides and extremities. On the head a light band crosses the anterior part of
