According to Boulenger there is no glandular latera] 

 fold, biit tbe light warts on the sides he speaks of are at 

 least in the great specimen placed one immediately behind 

 the other, thus forming something nearly like such a fold. 



The ground-colour is in the older olive brown, but in 

 three of the young almost black, in one grav. The lower 

 surface is in all without döts or marmorations. 



The species is previously recorded (by Peracca loc. cit) 

 from Bolivia. 



Bufo spinulosus Wiegm. 



Three specimens; one from Moreno, one from Casabindo, 

 Puna de Jujuy, Argentina, Erland Nordenskiöld 1901, and 

 the third from Mojos, Bolivia, Holmgren; 85,60, and 48 mm. 

 in length. 



Measures of the specimens show a great correspondence 

 in the different sizes; the only difference due to age to be 

 detected consists in the paratoids becoming longer and nar- 

 rower with age. In the smallest specimen they are just as 

 broad as long, but in the largest nearly twice as long. The 

 two smallest lack spines on the warts, the largest being very 

 distinctly spiniferous. In the smallest specimen the warts 

 have a tint of light red. 



The species is previously recorded from the mountain 

 regions both in Peru and Argentina.
