500 PROCEEDINGS OF THE ACADEMY OF 



Rana uarmorata nob. 



Two specimens of a frog, the coloration of which, though the animal is not 

 so large, corresponds with the figure of Rana esculenta, as given in the 

 Fauna Japonica. It differs, however, very considerably from the numerous 

 specimens of Rana esculenta in the Bonap. collection of the Academy. 

 The spots upon the back are not so regular and well defined as in e s c ul e n- 

 ta, and there exist on each side of the ventral line four or five longitudinal 

 elevations, resembling somewhat those of r u g o s a. The sides are marbled 

 with black, and there is a black band extending from the front of the eye to 

 the tip of the snout ; extremities black spotted ; thighs posteriorly marbled 

 with black ; under parts white. Length 1 inch 9 lines ; of anterior extremi- 

 ties 1 inch ; of posterior 2 inches, 10 lines. 



Habitat. Simoda. Five specimens obtained by Dr. Morrow. 



A small specimen of a Rana not figured in Schlegel, perhaps the young of a 

 large species is. 



Rana nigromaculata nob. 



Spec. char. Vomerine teeth in two patches between the internal nares ; olive 

 colored, with numerous black spots upon the back, of considerable size, but 

 varying in this respect ; a black band extending from the eye to the snout on 

 each side ; legs and tarsi banded with black, thighs mottled posteriorly with 

 blotches of the same color; under parts white ; web of the toes extending as 

 far as the base of the antepenultimate phalanx, except in the third, in which it 

 reaches to the base of the proximal extremity of the third phalanx. 



Dimensions. Length of head and body 1 inch ; of anterior extremities h an 

 inch ; of posterior l\ inches. 



Habitat. Japan. One specimen discovered by Dr. Morrow. 



In the collection of reptiles from Japan, by Dr. Morrow, is one specimen of 

 a Rana figured in Schlegel, considered by Prof. S. as identical with the 

 Rana temporaria of Europe. This species, however, has even a 

 stronger resemblance to the Rana sylvatica of the United States, with 

 which it r.ppears to be identical, and from which, indeed, I do not find 

 any marked points of difference. The large blotch behind the ear, and the 

 longitudinal black mark upon the arm exist, in all these specimens, and the 

 longitudinal ridge on each side of the body. Length of head and body 1 inch 

 11 lines ; of thigh 1 inch 2 lines ; of leg 1 inch 2 lines ; of tarsus 7 lines ; of 

 foot to extremity of longest toe 1 inch ; of arm 5 lines : of forearm 5 lines ; of 

 hand to extremity of longest finger 5 lines. Found in the Paddy fields back of 

 Simoda, Island of Niphon, Japan, May, 1855. This species has no cheek blad- 

 der. (Notes of Mr. Stimpson.) 



HYLID.E. 



Hvla viridis ? Laurenti. 



Syn. Ilyla arborea Schlegel, Fauna Japonica, p. 112, pi. 3, fig. 526. 



Habitat. Simoda, Japan; found in the mud in the Paddy fields back of 

 Simoda, Island of Niphon, May, 1855. The color during life, according to Mr. 

 Stimpson, is bright light green above. A golden band along each side of the 

 head, including the eye ; sides minutely sprinkled with copper color ; belly 

 white ; puffs at the throat. Five specimens. 



Gen. remarks. We can find no marked difference of structure between this 

 animal and the Hyla viridis of Laurenti, but no mention is made in the 

 description of the former of the golden band along each side of the head. 



POLYPEDATES VIRIDIS nob. 



Char. Head large ; snout truncate ; eves large ; nostrils small, two lines
