130 Hay — Batracldan& and Rejytiles of D. C. 



adults varying from olive brown to bright leaf green; below, white 

 slightly tinged with yellow: on the back there are often a few small 

 yellow specks. Small specimens will often be found to have a more or 

 less distinct white line extending about half waj' down the sides of the 

 body from the snout, and both pairs of legs with a whitish band on the 

 anterior surface. Length \\ inches. 



This frog which I first discovered near Mt. Vernon and regarded as //. 

 cinerea, has since been shown by Mr. G. S. Miller, Jr., to be a dis- 

 tinct species. My specimens were found along the shore of Little Hunt- 

 ing Creek, October 15th, 1892. They were immature and were evidently 

 looking for winter (juarters and were hopping about everywhere among 

 the damp leaves. 1 collected about fifty .sjiecimens, and on October 29th 

 secured another lot. On visiting the locality late in the following spring, 

 1 found them among the cat-tails and other large aquatic plants some 

 distance from the shore. Since then it has been observed in Swan Creek 

 and Messrs. Miller and Preble secured full grown .specimens from Four- 

 mile Run and at Dyke. Its note is quite unlike tliat of any of our other 

 frogs and consists of a series of high pitched, rattling croaks, which may 

 remind one slightly of the shrill grunts of a very young pig. 



19. Rana pipiens Schreber. Leopard Frog. 



Form typically frog-like; head rather pointed, its length contained 

 about three times in the bodj^ tympanum about as large as eye; the 

 dorso-lateral folds are rather prominent and between the two is a pair of 

 Indistinct, much broken, dorsal folds. Color ashy, olive, or bright green 

 above, uniform white or yellowish below; upperparts with irregular, 

 roundish, black blotches, margined with whitish, and arranged in two 

 irregular rows; usually two spots between the eyes; legs with two rows 

 of spots above. Length 3 to 4 inches. 



A common inhabitant of the marshes about Washington and well 

 known to the small boy as the " bloodynoun " or " bloodney." It is one 

 of the first species to come forth in the spring and and one of the last to 

 seek its winter quarters. lis notes appear to be somewhat variable, 

 but during the breeding season the cry is a highly characteristic snoring 

 croak or rattle. 



20. Rana palustris Le Conte. Swamp Frog. 



Very similar to the preceding species but with longer head and larger 

 glandular folds; of the latter there are distinctly two pairs, the dorso- 

 lateral and the dorsal; the dorsal fold is continuous as far as the pelvic 

 hump; the snout is usually obtuse and the form broader and flatter than 

 in the preceding species. Color pale greenish brown or ashy above, 

 yellowish white below; the blotches on the back are squarish and are 

 arranged in two quite regular rows; sides with two rows of spots smaller 

 than those on the back; hind legs conspicuously barred from the groin 

 to the toes. 



Fairly common, but usually living singly in cool pools or in the well-
