 I am not aware that as yet specimens have actually been taken within the 

 limits of the Territory.

Tongue very large, orbicular, without notch behind. Spade highly 

 developed. Color above dark olive-brown, with very indistinct blotches of 

 darker. Summits of dorsal pustulation whitish. Beneath whitish, the chin 

 black. Head and body, 2 inches long; hind leg, 2 J. This species is easily 

 distinguished by its nearly uniform and very dark color, without the light 

 lines of S. liolbroolui. — Descr. oritj. 



Two specimens of this species were taken in coitu in June, 1864, near 

 Fort Wingate, N. Mex., considerably extending the previously known 

 range, and indicating the period at which the sexes come together. The 

 animals were found on dry land at a distance from water, in this respect 

 differing from the species of Bufo, which, at the period of sexual excite- 

 ment, seek the water.
