 Rejiiarks. Tchnatohius angustipes is closely related to T. ntarmora- 

 tus, but differs from it in several characters, the most important of 

 which is the greater leg length. It is only in a country of such strik- 

 ing physiographic barriers as Peru that two species so closely related 

 may occur so near each other. 



BUFONIDAE. 



BuFO MARiNis (Linne). 



This extremely widespread species was met with at Palambla (8 

 specimens), Perico (6 specimens) and at Chumayo (5 specimens) while 

 a large series of tadpoles and very young were secured at Bellavista. 



BuFO SPiNULOSUS Wiegmann. 



This wdde ranging Andean toad was found at Huancabamba where 

 three large adults were caught and at Chumayo where three others 

 were taken. These bear close comparison with specimens from 

 southern Peru and the mountains of Chile and Argentina. 



BuFO TYPHONius (Linne). 



This form so characteristic of the tropical lowlands of South Amer- 

 ica was foimd abundantly at Perico, Bellavista, and Querocotilla 

 while four were found in the rain forest at Tabaconas.
