Description of Bufo globulosus Spix. 



Body medium. Head triangular, with sides nearly perpendicular. 

 Bony ridges on the crown strong, but not high, and not diverging 

 widely on the occiput; branches extend to the paratoids, in front of 

 each eye, and in front of the tympanum. Snout blunt, not protrud- 

 ing. Tongue widening a little backward. Tympanum medium, dis- 

 tinct, higher than long, height equal to half the length of the orbit. 

 Paratoids moderate, narrow, as long as the head, supplemented by a 

 row of warts on the flanks. When viewed from above they appear 

 exceedingly narrow and taper gradually. Warts flattened, smooth 

 on females, rougher on males. Fingers free, first and third about 

 equal, second longer, equaling the fourth. Tubercle at base of fin- 

 ger half as large as that in centre of palm. Tubercles on the foot 

 equal, inner shovel-shaped. Leg to extremities of toes as long as the 

 body. Toes half webbed. Tarsus with a cutaneous fold. Back 

 brown — light to dark — with broad rounded spots or bands of white; 

 on the hinder two-thirds of the body the white spots — more or less 

 irregular and confluent into bands — are disposed on each side of a 

 broad band of brown along the dorsum ; in front of this a white band 

 reaches the head. Some are more white than brown, others are of a 

 light reddish brown, nearly uniform. Thighs, legs and flanks banded 

 or spotted with brown and white. Below yellowish, white, smooth 

 as if glazed anteriorly, granulated and more yellow under the thighs. 

 The brown spot covering the anus is surrounded by white. Small 

 specimens are whiter. Length of body of largest four inches. Five 

 specimens from Rio Grande do Sul. Differs from B. ornatus Spix in 

 shape of head, low orbital ridges, coloration and shape of glands;
