10 vent 1 inch 2 lines; of tail 3 inches; of anterior extremities 10^ lines ; of 

 posterior IJ inch. Total length 4 inches 8 lines. 



Habitat. El Euceros le Jalapa, Mexico. One specimen, presented by Mr. 

 Pease. 



Gen. Remarks. In A. Sagrcei the supra-orbitar ridges are in contact. 



Anolis acutus, nob. 



Char. Head long and slender, with a longitudinal depression in front ; snout 

 prolonged, acute, supraciliary ridges in contact ; temples granulated ; dorsal 

 scales carinated ; the two or three middle rows the largest ; abdominal scales 

 carinated ; tail much compressed ; color brownish. 



Description. Head long and slender, with a longitudinal depression in front ; 

 snout prolonged, acute, rounded anteriorly ; nostrils of moderate size, circular, 

 their anterior margin nearly three-fourths of aline from the snout; they are 

 situated upon a prominence, above and within the extremity of the supra-orbitar 

 ridge ; scales in the depression immediately behind the nostrils smaller than 

 those upon the snout; behind the latter a double row of large smooth hexagonal 

 scales ; these are a continuation of the supra-orbitar ridge, which is composed of 

 five or six large and smooth scales, the anterior one the largest; these ridges are 

 closely in juxtaposition ; the scales at the bottom of the frontal cavity are much 

 smaller than those forming its borders; occipital plate longer than broad, sub- 

 oval, surrounded with scales, its anterior angle almost in contact with the pos- 

 terior border of the supra-orbitar ridges; eight quadrangular plates along the 

 margin of the upper jaw ; three or four rows of scales between the superior marginal 

 labial plates and the sapra-orbitir ridge; temples covered with granulations ; auricular 

 openings large, circular, not distinctly denticulated ; scales upon flanks granu- 

 lar, much smaller than those upon back and abdomen ; dorsal scales carinated, larger 

 than most of those upon the back ; a moderately developed gular pouch extend- 

 ing from the chin to the abdomen; extremities slender; tail much compressed, 

 except at the base., verticillate, the verticilke near the root about 1| lines apart; 

 three or four rows of large and carinated scales beneath the tail ; under surface 

 not denticulated, upper very slightly; scales upon superior margin of arms and 

 thighs slightly carinated ; posterior surface of thighs covered with granulations. 



Coloration. General tint chocolate brown above with a tinge of green ; under 

 parts bluish ; two brownish lines en chevron upon the neck ; a brownish inter- 

 rupted line stretching across the occiput ; body brown spotted ; snout of a lighter 

 brown. 



Dimensions. Length of head 9 lines ; greatest breadth 5 ; length of body to 

 vent I2 inch; (tail mutilated.) 



Habitat. Cuba ? 



Gen. Remarks. This species would appear to correspond with A. nasicus, D. 

 k B., but in that the ventral scales are smooth. 



Anolis augusticeps, nob. 



Char. Head long and narrow, temples granulated ; scales upon back and abdo- 

 men smooth ; tail moderately compressed, with a larger row of scales above 

 along the median line ; color light pea green, with numerous black spots and 

 undulating lines. 



Description. Head long, narrow, snout acute, rounded in front ; anterior mar- 

 gin of nostril situated about half a line in front of extremity of the snout; nos- 

 trils latero-superior, the prominence, which is usually observed near the ex- 

 tremity of the snout, beng in this species scarcely observable : supra-orbitar 

 ridge composed of four or five large scales, in contact in front, separated in the 

 middle by three very small scales ; occii)ital plate much longer than broad, sur- 

 rounded by polygonal scales differing much in size, separated laterally and 

 anteriorly from the supra-orbitar ridge on each side by a small plate ; eight or 

 nine plates along the margin of the upper jaw, on each side four or five poste- 

 rior teeth larger than the others ; temples covered with granulations ; external
