BATRACHIANS OF THE VICINITY OF NEW YORK 197 



Anderson's Tree Toad, Hyla andersoni Baird (Fig. 21), is 

 of moderate size. The disks on the toes are well developed. 

 Bright pea-green above with a narrow, though very 

 distinct, white border on the sides and upper surfaces „ ^^°°/ 

 of the limbs. A narrow, purplish brown band extends 

 from behind each nostril, across the eye and to the base of the 

 fore limb. The lower sides are purplish brown, though of a 

 lighter shade than the band, and are ornamented with irregular 

 spots of a lighter and richer hue. The abdomen is pinkish 

 white, though its edges are suffused with the purple tinge of the 

 sides. 



This species is of great rarity, and but very few specimens 

 have ever been captured. It is a most attractively colored 

 creature, and on account of the pale green of the upper surface 

 resembles the European Tree Toad. Mature specimens are 

 from an inch and a quarter to an inch and a half in length. 



Range: The species is so rare that its range has not yet been 

 determined, but is supposed to extend from southern New York 

 to Florida. The species has been found in South Carolina. 



Local Distribution: One specimen has been taken at Jackson, 

 N. J., another at May's Landing and still another (represented 

 in the figure) at Lakehurst, in the same State. 



The Gray Tree Toad, Hyla versicolor Le Conte (Figs. 22 and 

 28), is of moderate size and stout form. The ends of the toes 

 are disk-like and adhesive. Color above, usually pale 

 lichen-gray, with large wavy and irregular markings ^^^J^^^^ 

 of darker shade. On the hind limbs these darker 

 markings are so disposed that they appear to form two bands 

 when the limbs are folded. Abdomen uniform grayish white; 

 lower portion of hind limbs tinged with bright yellow. 



The skin is very rough and is covered with minute, warty 

 points on the back. Male specimens differ from the females in 

 having loose, dark skin under the throat. 



The species exhibits great variation in color according to 



light, temperature and the temperament of the individual. 



From the pale, ashy gray ordinarily present, the color varies to 



brown, very dark gray, or to vivid green. With the variation
