the back, and the lower surface is punctate with black. Our speci- 

 mens possess rudimentary cutaneous expansions ; this is the only 

 respect in which they differ from the description of B. ocellaius Gthr. 

 Since the habits, shapes of paratoids and positions of spots and 

 warts are similar, and the transition from the large to the small so 

 gradual, it is not possible to consider them as representing more than 

 a variety. 



The species B. iclericus Spix cannot be retained as synonymous. 

 A difference by which it can be distinguished most readily is that of 

 the shape of the paratoids. In this the glands are regular elongate 

 oval, and twice as long as wide ; in B. agua Latr. they are rhomboi- 

 dal, nearly as broad as long, and usually pointed at the hinder 

 angle. Specimens of less than an inch in length show these differ- 

 ences distinctly. 



0;her species found in various collections examined are distributed 

 as follows: 



B. granulosus Spix. Valley of the Amazon. 



B. ornalus Spix. Bahia to Rio Janeiro. 



B. ictericus Spix. Espiritu Santo and Rio Janeiro. 



B. globulosus Spix. (description appended). Rio Grande do Sul. 



B. D'Orbignyi D. and B. Argentine Confederation. 



B. chilensis D. and B. Peru, Bolivia and Chili. 



B. valliceps Wiegm. Mexico and Texas. 



B. lentiginosus Holbr. Mexico and United States. Several varieties. 



Hyla Baudinii D. and B. 



a. A specimen on which the color of the back is a clouded dark 

 brown. On the legs the brown is broken with white, and behind the 

 thighs there are two large white spots. The brown becomes darker 

 on the flanks near the borders which are quite irregular. Spots of 

 brown are scattered in the white of the lower portions of the sides 

 and the under surfaces of the legs. 



b. A half-grown specimen of a light brownish red, with reddish 

 brown in a band from the nostril through the eye to the middle of 

 the flank, in bands on the arms and legs, and in a few spots on the 

 dorsum and sides of the legs. The pair of spots on the thigh is indi- 

 cated by the border of dark, which is all that appears. 



Hyla maxima (Laur.) Giintli. 



The medium sized are more uniform in coloration than the larger 

 and the small; the latter have the markings in most distinct outline. 

 All possess the black line on the dorsum and bands across the flanks.
