NATURAL SCIENCES OP PHILADELPHIA. 179 



plane above. Nares large, lateral. Frontal concavity elongate deep, its scales 

 numerous, granular. Facial rugas moderately developed, divergent, soon ob- 

 solete, covered by three scales anterior to the seven superciliary, and sepa- 

 rated from the canthus rostralis by larger keeled scales. The canthus is weak, 

 concave. Occipital plate small, oval, surrounded by granular scales, which 

 also separate the snperciliaries. Palpebrals keeled ; muzzle plates polygonal, 

 tricarinate. Loreal rows about seven ; upper labials eight, inferior seven, 

 infralabials small. Anterior extremity slender, not reaching the groin, the 

 external digit shorter than the second ; posterior extremity reaches the ante- 

 rior margin of the orbit. Auricular orifice large, vertical. Length from muz- 

 zle to axilla 9 1.; from auricle to vent 1 in. 3 1.; of hinder extremity 1 in. 4 1. 



Above bronze brown, beneath rusty white, separation between the two ab- 

 rupt anteriorly ; lips and femora beneath varied with brown. Another speci- 

 men is brownish golden above, light yellow beneath. 



This species differs from fuscoauratus in the uniform size of the 

 dorsal and lateral scales, and the absence of a larger median caudal row. In 

 radulinus, poecilopus and f r a s e r i the ventral scales are keeled. 

 In the last there is no occipital plate, and the second has the scales of the 

 muzzle no larger than those of the front. A. radulinus exhibits a few 

 larger dorsal rows. In general appearance it is quite similar to A. 1 i o n o t u s. 

 It inhabits tbe same country, viz. : Veragua. Mus. Academy Nat. Sciences,

Anolis (Dracontura) poecilopus. 



Size medium ; neck and hinder extremities elongate ; head broad, muzzle 

 full, rather prominent. Tail compressed cylindrical, its scales keeled, the 

 median row largest. Abdominal scales small, ovate, keeled ; lateral minute, 

 gradually merging into the dorsal, which are larger, flat, keeled and in nume- 

 rous rows. All the scales of the extremities are keeled, those of the internal 

 surfaces minute, the others flat, not large. The scales of the upper surface 

 of the head are minute, subgranular, rugulose ; those between the canthus 

 rostralis and facial ruga larger. The canthus weakly pronounced, soon obso- 

 lete ; rugae slightly developed, bounding a rather deep frontal concavity, 

 which extends between the orbits. Nostrils near the end of the muzzle, 

 lateral. Seven or nine snperciliaries bounded internally by granules ; occi- 

 pital minute or wanting. Superior labials nine ; infralabials small. Palpe- 

 brals small, keeled. Loreal series nine or ten. Auricular orifice small, vertical. 

 No dorsal or nuchal fold ; goitre large. Anterior extremity reaching groin ; 

 second finger longer than fifth ; posterior extremity reaching end of muzzle ; 

 digital expansions narrow. From muzzle to tympanum 8 lin.; tympanum to 

 vent 2 in.; tail 4 in. 8 lin.; posterior extremity 2 in. 1 lin. 



General color above, brown ; the extremities and digits with numerous light 

 cross-bands ; sides darker, with numerous longitudinal light lines, one com- 

 mencing above the axilla most distinct ; light vertical bands ascend from this 

 to a superior obsolete longitudinal band. In female specimens dark chevron- 

 shaped spots cross the back. Beneath pale yellowish. 



Habitat. Near Carthagena, and on the Truando, New Grenada. From 

 Lieut. Micheler's collection, made by Arthur Schott. (Sm. No. 4320, 4331.) 



This animal probably most nearly resembles the A. fraseri, Gthr., but 

 that species is said to have but five rows of loreal scales, the fifth finger 

 longer than the second, and different coloration. In general appearance it 

 approaches near to A. 1 i m if rons, fuscoauratus and lionotus. In 

 the last the dorsal scales are much larger and smooth ; the scales of the front 

 and muzzle are also larger. 



Anolis (Dracontura) vittigerus. 



Head rather broad, muzzle short. Tail cylindrical, four times the length of 

 the head and body. Anterior extremity just reaching the groin, posterior ex-
