in profile. Nostrils lateral ; scales of the middle and extremity of the muzzle 

 small, numerous. Occipital elongate oval, not in contact with the supercili- 

 aries. The latter, four on each side, separated on the medial frontal line (which 

 is concave), by a series of very small scales. Facial rugae almost obsolete, 

 enclosing an ovoid concavity, broader anteriorly, which is occupied by elon- 

 gate smooth scales. Three or four palpebrals of large size, surrounded by 

 several smaller plates, some of them weakly keeled. Canthus rostralis short ; 

 loreal scales in eight series. Superior labials eight. One large symphyseal 

 scarcely divided; no larger series (" infralabials") beneath the inferior labials. 

 Goitre moderate. Scales of the sides small, not keeled ; of the belly larger, 

 smooth ; of the back still larger, in about twelve rows, smooth ; no dorsal or nu- 

 chal crest. Tail stout at the base, compressed, the median superior scales flat, 

 offering no rudiment of a crest. Digital expansions narrow. Anterior extremity 

 reaching to the groin ; the posterior, to the nostril, when extended forward. 

 The scales of the upper surfaces of the extremities, moderate, flat, weakly 

 keeled. 



General color above, bronze brown, with a few darker shades on the dorsal 

 region. Tail and hinder extremities paler, femora light spotted behind. A 

 light band extends from the angle of the mouth to the middle of the side. 

 Beneath it there are brown vermiculations, which become darker near the 

 groin. Belly immaculate ; lips dark. 



One specimen in the Museum of the Academy, sent from Cocuyas de Vera- 

 guas, New Grenada, by Mr. R. W. Mitchell. 



Anolis (Dracontura) cyanopleurus Cope. 



Size small ; form very slender. Head elongate, facial ruga? weak, converging 

 anteriorly above the plane of the canthus, enclosing an elongate concavity. 

 Series of superciliary plates not in contact medially, and separated from the 

 occipital all tricarinate. Scales of the muzzle smaller, tricarmate. Two or 

 three tricarinate palpebrals; six loreal rows. Upper labials six or seven; 

 infralabials small, keeled. Six dorsal rows of more or less hexagonal plates, 

 smooth or tricarinate, equal to or larger than those of the belly, which latter are 

 strongly keeled. Scales of the sides small. Scales of the upper surfaces of 

 the extremities flat, keeled. Tail three times the length of the body, slightly 

 compressed, the scales of its median line similar to those of its sides, keeled. 

 The posterior extremity extended reaches the middle of the frenal region. 

 Digital dilatations narrow. Total length 5 in. 6 lin. ; tail 4 in. 2 lin. 



Under surface of head, body, extremities and base of tail, golden greenish 

 yellow ; a broad dorsal band of the same, involving only the six rows of large 

 scales. This band divides upon the nape, sending a narrow line to the poste- 

 rior border of each orbit. Occiput and sides deep blue, the latter darker near 

 the dorsal band, where it is sometimes marked with a longitudinal series of 

 golden dots. The muzzle and side of the head are dark bluish or blackish ; 

 in the males the goitre is large, and, with the abdomen, of a pale bluish tint 

 not golden, as in the female. In the former, the posterior extremities are 

 marked with a few light cross bars ; in the latter the femora have an additional 

 light posterior border. 



The specimens described were found at Monte Verde, Cuba, and sent to the 

 Smithsonian Institute, by Mr. C. Wright, (Type No. 5737.) Some of them have 

 been presented to the Academy's Museum. The species is one of the most 

 elegant and brilliant of the charming little group designated by some authors, 

 as it appears to me without sufficient reason, as a genus, under the name of 

 Dracontura. 



Anolis (Dracontura) o p h i o 1 e p i s Cope. 



Size small ; tail less than twice the length of the body. Occipital plate not 

 in contact with the superciliaries ; the latter, four on each side, the two ante- 

 rior largest, equal, not separated from the palpebral disc by small scales, in 



1861.]
