FAMILY RANID.E. 63 
_ Description. Head short ; snout obtusely rounded. Nostrils equidistant between the eyes 
and snout. Eyes large and prominent. 'Tympanum small, rounded and polished. Buttocks 
granulated. Joints of the toes with fleshy tubercles. 
Color. This appears to vary considerably with age: In the young, the general color of the 
upper part of the body is frequently of a brilliant golden green; the adult is usually pale 
brown. The spots along the back vary with age from rufous brown to deep black ; these are 
more or less of a quadrate form, and larger than the row on the sides, which are often rounded. 
The spots of the dorsal series become occasionally confluent, producing a dark longitudinal 
band on each side. A dusky line, more or less obvious, proceeds from the eye to the snout ; 
other lines parallel with this on the sides of the head. A greenish or yellow longitudinal line 
proceeds from the orbit to the posterior part of the body on each side, separating the dorsal 
from the lateral series. ‘T'ympanum of the general color of the body. Beneath soiled white, 
or tinged with yellow, which increases in intensity towards the tail. Fore legs short, brownish, 
with dark subocellate spots. Posterior extremities yellow beneath, brown or rufous above, 
with twelve to thirteen black annular bands margined with lighter; these bands are more 
usually uniform dusky greenish or brown. Similar, but oblique bands or spots on the fore 
legs. Eyes black, with a golden lustrous ring. 
Length 2°0 - 3-0. 
This is one of our most beautiful frogs, and is remarkably active. It has a strong and dis- 
agreeable odor; and from being used as bait, it is called, in various districts, Pickerel Frog, 
and also Tiger and Leopard Frog. It occurs along salt marshes, and in wet meadows near 
ponds and streams. I observed it in the most elevated regions in the northern part of the State. 
Its geographical range, along the coast, extends from Maine to Virginia. Westward, it has 
been noticed in Ohio.
