172 PROCEEDINGS OP THE ACADEMY OF 



Above light brown, below and on upper tip yellowish, abruptly sepa- 

 rated from color of upper surfaces, which is on sides a dark band from eye, 

 extending in 9 only to groin, and is bordered below with distinctly paler to 

 middle of side. 



Two specimens. West Equador. From Fraser's collection. 



Anolis scypheus, 



Lateral scales minutely granular, graduating into larger, many rowed, 

 keeled dorsals, which are very much less than ventrals, and less than fron- 

 tals. Superciliary row not continued as larger scales to canthus, com- 

 posed of nine scales, separated by three rows of keeled scales ; twelve rows 

 at middle of muzzle between canthus rows, as broad as long, obtusely one- 

 keeled. Canthus rostralis descending steeply, nearly straight, from lachrymal 

 processes to same, equal from same to end of muzzle, and longitudinal diameter 

 of orbit. No prefrontal concavity. Frontal and occipital region elevated. 

 Eight loreal rows. Supraorbitals very small, on inner part of the region, in 

 longitudinal series, keeled ; rest of surface granular. Occipital not large, sur- 

 rounded by many flat scales, and between two bony crests, which unite pos- 

 teriorly to it, send off a posterior median crest, which after 2" length, sends 

 off a nearly transverse branch on each side. Ear \ size of eye opening. In- 

 fralabials small, longitudinally keeled. Keeled scales of limbs much smaller 

 than abdominal ; caudals very small, equal at root of tail. Trace of goitre in 

 9- Digital dilitations very narrow. From end of muzzle to ear V Q'"; to 

 vent 6" 8'"; vent to end of tail 11" 2"'; hind foot 2" 6'"; groin to heel 3" 8'". 



Bright green; brown band across muzzle and eyelids, and some small white 

 specks. Narrow blackish cross-bands directed forward on sides, and longi- 

 tudinal reticulations from axilla. Femur ? twice, tibia once brown cross- 

 banded. Immaculate below ; throat bluish. 



Anolis u s t u s. 



Resembles superficially alutaceus anddamulus. Head flattened ; 

 muzzle acuminate ; greatest width between posterior scales of canthus ros- 

 tralis from same point to anterior margin of nostril, which is lateral, and 

 near end of muzzle. Ridges scarcely perceptible ; concavity shallow, broad, 

 three scales wide. Scales of front broad as long, slightly one-keeled, in 

 six or seven rows between canthus ; five rather large superciliaries which 

 are in contact, or separated by one row of very small scales ; occipital 

 large, surrounded by flat scales ; supraorbitals five or six ; three broad, 

 smooth on inner row, in contact with superciliaries, except on one side of one 

 specimen. Dorsal scales smaller than caudal, ventral or prefemoral. Five 

 loreal rows ; canthus nearly straight ; ear J of eye; dilatations well devel- 

 oped ; goitre weak. Infralabials few, small, shorter anteriorly. Tail a trifle 

 more than twice head and body; muzzle to ear 1" 2 /// ; ear to vent 2" 9 /// . 



Yellowish brown, with several short, irregular, darker, lighter bordered, 

 half-fasciae above. Head darker above ; streak across between eyes. Gular 

 and lateral regions with ferruginous small spots and shades. Tail with trans- 

 verse dark shades. Extremities darker, paler, few cross banded. 



Two specimens. B. M. Belize. 

 Anolis h e 1 i a c t i n. 



Size small ; head large, elongate, depressed ; ridges weak ; concavity shal- 

 low, short ; fourteen more or less rows of narrow, keeled, not imbricate dor- 

 sal scales which graduate into the granular lateral, and are smaller than the 

 imbricate ventral: the last about equal to those on the middle of the front. 

 Interrugal scale shield-like, broad as long, faintly keeled; a little larger than 

 those of the ridges : these are continued as a row to the middle of the can- 

 thus rostralis, and number nine scales from that point to posterior extremity 

 behind orbit; they are separated by two rows of small scales, and two on 

 each side from the round flat occipital; also by one row from supraorbital
