NATURAL SCIENCES OP PHILADELPHIA. 481 



ovoid depression, the scales of which, are smooth ; those upon the snout cari- 

 nated, as also the scales upon the abomen ; the colors of these specimens are 

 much darker than that of another ; brownish above, and orange colored 

 mingled with yellow beneath ; in the other, the general color is golden yel- 

 low, lighter beneath, with a tinge of white upon the abdomen. Total length, 

 5 j inches ; of tail, 2 inches 8 lines. Found also in Surinam. (D. & B.) 



Anolis longicauda nob. 



Spec. char. Scales upon the muzzle keeled ; eight superior labials ; scales 

 of abdomen carinated ; dorsal scales indistinctly carinated ; median rows 

 larger ; 'tail very long ; color green ; gular pouch orange, with two indigo- 

 colored lateral stripes, one on each side. Total length, 5 inches, 5 lines. 



Description. 44 teeth in the upper jaw ; 10 posterior tricuspid; 43 in the 

 lower ; the 10 or 11 posterior distinctly trilobed ; scales upon the muzzle 

 keeled ; two crests upon the head, prolongations of the superciliary ridges, 

 circumscribing laterally a longitudinal depression, broader in front ; the 

 scales in this depression polygonal, much larger than those upon the muzzle, 

 keeled ; eight superior labials ; six rows of scales upon the side of the head 

 anteriorly, between the superior labials and its upper margin ; auricular open- 

 ing moderate ; abdominal scales much the largest, keeled ; those upon the sides 

 very small, granular ; back covered with polygonal scales, indistinctly 

 carinated ; several of the median rows larger than the others ; breadth of head 

 posteriorly, one-half of its total length ; body and extremities slender ; tail 

 very long and tapering, round at base, more than double the length of head 

 and body ; color bluish above, probably green during life ; lighter upon the 

 tail ; abdomen, chin, under part of tail and extremities very light blue ; gular 

 pouch orange with two indigo -colored stripes, one on each side. Total 

 length 5 inches, 5 lines ; of tail, 3 inches, 10 lines. One specimen. 



Gen. remarks. This species is quite different from An. sericeus, a Mexi- 

 can species, in which the scales upon the back are granular, and of nearly 

 equal size ; it is also a stouter animal, and the tail is shorter. Anolis tro- 

 pidogaster nob., from New Grenada, is destitute of the two well marked 

 crests so characteristic of this species, and the plates lying at the bottom of 

 the longitudinal depression between them are much longer than those on the 

 corresponding position in tropidogaster; and the shape of this de- 

 pression is quite different, being much broader in front, in longicauda. 

 In Anolis pulchellus D. Sr B., the carinations of the scales before the 

 back and abdomen are indistinct ; whereas, in the present species they are 

 well marked : the tail in the former is but one-third the total length. 



Anolis cupreus nob. 



Spec. char. Scales upon muzzle carinated ; supraorbital ridges separated 

 by several rows of scales; three or four rows of scales inteivening between 

 each interorbitar ridge and. the occipital scale ; six superior labials ; abdominal 

 and dorsal scales very distinctly carinated ; those upon tail very strongly 

 keeled ; copper colored above, whitish beneath ; throat orange ; in some 

 specimens a black spot upon the shoulder. Length of head and body 1 inch 

 8 lines. 



Description. A small species. Scales upon the muzzle very distinctly cari- 

 nated ; supraorbitar ridges separated by several rows of scales ; three or 

 four rows of scales intervening between the supraorbitar ridge and the occipital 

 scale ; six or seven supraorbitar scales separated from the supraorbitar ridge 

 by a single row of granules ; three scales carinated, and two of them much 

 larger than the others ; six superior labial scales ; six or seven rows of scales 

 upon the sides of the head anteriorly above the supraorbital ; auricular 

 opening moderate ; scales of the flanks smaller than those upon the back and 

 abdomen ; abdominal and dorsal scales very distinctly carinated ; those upon
