Hylidae 



National Museum. Cope, in " Batrachia of North America," 

 says, " From the Chorophilus ornatus the Chorophilus occidentalis 

 differs in colour entirely (it is described as chestnut instead of 

 grey); the head is more acute and the cleft of the mouth deeper; 

 the legs are longer and the granulation finer."' 



Chorophilus occidentalis is reported from Georgia (Rice- 

 borough, Liberty County, Allapaha), Florida (Jacksonville), 

 Mississippi (Bay St. Louis), and Texas (Dallas). 



CHOROPHILUS OCULARIS, HOLBROOK 



Identification Characteristics 



Colour: Chestnut-brown, with an obscure dorsal stripe of 

 darker colour. This stripe extends from the end of the muzzle 

 to the posterior back, forking posteriorly. There is a stripe on 

 each side of this, and a more pronounced one below along the 

 side of the head, through the eyes and ears and along the sides. 

 Upper jaw edged with white; the white line extends backward 

 to a point beyond the shoulder. Outer edge of tibia occupied 

 by a light line set off by darker colour above. Below, yellowish, 

 with obscure spots on breast and throat. 



Measurements: Size small, i. e. length i inch or less. Legs 

 long, length to heel equalling or exceeding the total length of 

 the frog. Tibia longer than femur. 



Structure: Skin smooth. Head pointed; eyes large; ear 

 small, less than half diameter of eye. 



Range: Specimens are from Charleston, South Carolina. 



This species is said to be the smallest among North American 

 Hylas. Its unusual characteristics seem to be the pointed jaw, 

 the long legs, and the light line along the outer edge of the tibia. 

 The colour pattern evidently agrees with that of Chorophilus 

 nigritus. 



These tree frogs are reported to frequent aamp places, such 

 as the vicinity of stagnant pools. They are very active, cover- 

 ing two feet or more at a single leap. The rich brown of the upper 

 surfaces has great metallic lustre. 



1 Although these differences are not marked in the type specimens in their present condition, 

 they will have to be relied upon until further investigation is made upon fresh material.
