portion of the ovhit to the uj))h'1' edj^e of tlio same insertion ; the two 

 are oblique and paralh'l. They are sei)arate(l by a narrow light (even 

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

 riinninff to tho middle of the insertion of tiie arm. IJehind the arm and 

 on the side of the body is a still larj-er blotch, similar and parallel to 

 the last mentioned, i'.nd behind this and hi.uher upon the baek still 

 another, anteriorly eoverinf>' the loins on each side, and innniiif;' ob- 

 liquely baelvwards so as to be parallel to the others. The blotehes of 

 this posterior pair are separated by the narrowest |>art of the j;reen 

 stripe, which is bounded to a considerable distance by these blot<!hes. 

 All the blotches Just descrilted, as well as that >n the lop of tlu^ head, 

 are «lark brown, margined by a lijihter aicola, which on t-lu^ sides and 

 back is sometimes yellowish in life. The under ])arts aic yellowish- 

 white or pun^ white; the throat sometimes bri.uht yellow; souu'times 

 closely or si)arsely crowded with dark spots. There aic no w«'ll-de- 

 lined darker blotches on the arm ; but the thj^li, lej;', tarsus, and loot 

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

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

 small blotches, some of which are oceasionally continent into an irre<'- 

 ular dark line alonji the anterior and ixtsferiiw faces of the thijih. The 

 granulation about the buttocks is usually wliit«'. 



A specimen from Hussellville. Ky., has the blotches much snmller 

 than usual. 



In a specimen from (Carlisle the last vertebra has the transveise 

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

The iris of this subspecies is golden and capable of exctessiviM'ontrac- 

 tion. A broad blackish spot o(;cupies it at each end <»f the pupil, and 

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

 tracted the])npil is shortly transverse, not linear as in many llyke, and 

 the brown sjtots are triangles, their apices inwards. 



Specimens from the lower Mississippi ar«' lre«pH'ntly of <»bscnre colois, 

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

 distinguish theuj as foiining a constant subspecies. Mr. IJonlcnger, 

 (Catal. JJatr. Sal., Ibit. Mas., ISSli, p. .J.'JT) refers such a specinu'n to a 

 "var. bufonia." 



In connection with metachrosis in this species 1 obsei'ved in a speci-

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

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