ter of the orbit ; tip of first finger extends slightly beyond the tip of 

 second ; toes about half webbed, with simple subarticular tuber- 

 cles, a narrow tarsal fold. The leg carried forward along side of 

 body, the metatarsal tubercles reaches hinder margin of the orbit. 

 Parotids not very conspicuous, about twice as long as broad. 

 Tarsal tubercles two, smaller than the metacarpal 'cles. 



Upper part of the body covered with small distinctly porous 

 warts. Belly granular, somewhat warty on chin and under the 

 thighs, no evident pores. 



Tongue elliptical, its width if in. its length. 



Color uniform, slate colored, slightly lighter anteriorly. Throat 

 and phin same color as the back, except being more or less 

 sprinkled with white ; belly white. 



The variety here described is more slender, has a more pointed 

 snout, and less developed parotids than the typical B. viridis, 

 Laurenti, as described by Dr. Boulenger. The uniform slate 

 color on the upper part of the body extends on the chin and 

 throat, though being some speckled with white. 



In our specimens there is no trace of a vertebral line. 



As described by Dr. Boulenger Bufo viridis is a very variable 

 species and has a wide geographical range. No doubt a more 

 critical study of a larger number of specimens from different 

 localities would result in the discovery of several well-marked 

 geographical varieties.
