portion of the orbit to the upper edge of the same insertion; the two 

 are oblique and parallel. They are separated by a narrow light (even 

 white) line, extending from the orbit a little behind the lowest part and 

 running to the middle of the insertion of the arm. Behind the arm and 

 on the side of the body is a still larger blotch, similar and parallel to 

 the last mentioned, and behind this and higher up on the back still 

 another, anteriorly covering the loins on each side, and running ob- 

 liquely backwards so as to be parallel to the others. The blotches of 

 this posterior pair are separated by the narrowest part of the green 

 stripe, which is bounded to a considerable distance by these blotches. 

 All the blotches just described, as well as that on the top of the head, 

 are dark brown, margined by a lighter areola, which on tlie sides and 

 back is sometimes yellowish in life. The under parts are yellowish- 

 white or pure white; the throat sometimes bright yellow; sometimes 

 closely or sparsely crowded with dark spots. There are no well-de- 

 fined darker blotches on the arm ; but the thigh, leg, tarsus, and foot 

 each exhibit two or three transverse ones. The buttocks are yellow- 

 ish, wfth the arms brown, and the posterior and anterior faces, with 

 small blotches, some of which are occasionally confluent into an irreg- 

 ular dark line along the anterior and jiosterior faces of the thigh. The 

 granulation about the buttocks is usually white. 



A specimen from Eussellville, Ky., has the blotches much smaller 

 than usual. 



In a specimen from Carlisle the last vertebra has the transverse 

 apophyses very little dilated, though somewhat enlarged at the ends.

The iris of this subspecies is golden and capable of excessive contrac- 

 tion. A broad blackish spot occupies it at each end of the pupil, and 

 a narrow black line above and below the latter. When the iris is con- 

 tracted the pupil is shortly transverse, not linear as in many Hyhe, and 

 the brown spots are triangles, their apices inwards. 



Specimens from the lower Mississippi are frequently of obscure colors, 

 of rather larger size, and with large tubercles. I have not been able to 

 distinguish them as forming a constant subspecies. Mr. Boulenger, 

 (Catal. Batr. Sal., Brit. Mus., 1882, p. 337) refers such a specimen to a 

 "var. bufonia." 



In connection with metachrosis in this species I observed in a speci- 

 men latelj^ dead that on the end of the muzzle, palpebrie, canthus ros- 

 trails, outer line of humerus, ends of sacral diapophyses, where the 

 derm was in a state of tension, that it assumed a bright green hue. 



The note of this species may be exactly imitated by striking two 

 marbles together first slowly, then faster and faster, for a succession of
