oyc is ill! c'lon.n'iited blotcli of diirk brown, passiiij^ obliquely backwards 

 towards its fellow, k-avin-j: a space* between and I'orinin^' an interrupted 

 V. i'osterior to these and in tlie anterior portion of tlio back is a 

 single very large blotch, snbcruciforni in shape, from sending out a 

 bran(;h on each side towards the ey(>, more, or less i)arallel with the 

 blotc^hes tirst inenlioned. The i)osierior corners are also obliquely 

 elongated to a greater or less extent. Iinniediately behind the large 

 blotch may be usually traced two others, which arc elongated, and 

 extend obli(piely to the sides of tlio body in a direction generally par- 

 allel with the outer edges of the dorsal blotch. A dusky, indistinct 

 bar extends from the eye along the upper edge of the face through 

 the nostril to the tij) of the snout, and the edge of the upper jaw is 

 more or less marbled with the ground colors. A conspicuous spot of 

 light gray (with dark border) is always visible among other markings 

 beneath the i)osterior half of the eye nnd on the i)osterior portion of 

 the U]>per Jaw; it is a little in advan(;e of the tympanum and some- 

 what longer. A dusky, indistiut^t mottled band passes from the eye 

 backwards through the tympanum along the side of the body, dark- 

 est along the undulating upi)er edge, where it is nuirgined sonu^times 

 by yellowish-white. The fore-arm has two transverse dark bands; the 

 thigh, leg, and tarsus each the same number. All the surfaces of 

 limbs concealed when tlexed are vermiiMilaled with brown on a yellow- 

 ish ground, the: light intervals angular, even on the inside of tibia and 

 foot. The anfeiior and posterio- 'aces of the thigh and leg are yellow, 

 sharply and jiarrowly marbled v, ;th bn \ n. Ueneath yellowish-white. 

 i\rales, in sjjring, with the gular sac, mixed ash, brown, and white. 



Specimen described fiom (Jrosse Isle, IMich. 



The females dill'cr mainly in the smaller tympani. 



In other specimens, fioin ('arlisle, Pa., there is evident a constant 

 dark spot on the side of the upper Jaw and bf neath the anterior half of 

 the eye, the light spot already described being situated between it and 

 a narrow dark line in front of the tympainun. Sometimes the entire 

 back, l>y the conlluenise of the blotches described, is occupied by a large 

 mottled cross, the anterior fork very short. The anterior face of the 

 arm is blotched with dark; the posterior marbled like the thigh. Some- 

 ti'i'.'S the blot(;hes are more or less obsolete; at others they are reduced 

 in size, althouj;!! usually ci iicifcuin in their arrangement. The color of 

 the back is sometimes grass-green, with (he dark blotches, which vary 

 in extent. 



In the southern and western specimens there is a tendency to a re- 

 placing of the brown leticulation on the yellow ground of the jjosterior 

 lace of the thighs by a nuinbei' of snbcirculai' golden spots in the brown 

 ground, as in the Il./cmotudis, although northern specinuins sometimes 

 show traces of it. This is very evid 'ut in specinuMis from Prairie Mer 

 Ilonge and Tangipahoa Itiver, Loui.-suimi, and I)alla>' Tex. As ix gen- 

 eral rule, too, the ])ortions of the limbs concealed, or in contact with 

 each other when Hexed, are in norlhern apecainens more fully nmrblcd
