Bufo d'orbigrnyi Dum. & Bibr. 



19 specimens from Tatarenda, Bolivia, Chaco. E. Nor- 

 denskiöld 1902. 30—73 mm. 



As far as I can see, this species is not before recorded 

 from Bolivia. It seems to be very common at Tatarenda. 



Hyla raddiana Fitz. 



According to Berg, Batracios Argentinos in Museo na- 

 cional de Buenos Aires, Tom 5 p. 201, this is the correct name 

 for Hyla pulchella Dum. & Bibr. (Boul. Cat. Batr. p. 375). 



One specimen, 56 mm. in length; from Volcan, Andes of 

 Argentina -^ij 1901. Erland Nordenskiöld. 



The specimen is a male, but does not agree with the 

 variety of coloration Boulenger mentions as being possibly 

 characteristic for the males; it rather corresponds with the 

 supposed female coloration. There is a distinct curved claw 

 on the inner side of the thumb contrary to the statement in 

 Cat. of Batr., but still there is no doubt that it belongs to 

 this species. (Tt is not a Hyla bracteator as it is characterized 

 in Cat. Batr. sal. {= Hyla gilntheri Boul. according to Berg 

 loc. cit.).) According to Berg the frog that Hensel in Archiv 

 f. Naturgesch. 1864 p. 159 described under the name of Hyla 

 bracteator is synonymous with this form, and as the male of 

 this one is also provided with such a claw, one may presume 

 that in some cases at least such a structure appears in the 

 males of this species, too. 



Hyla nasica Cope. 



Two specimens from Bolivia, Chaco. Erland Nordenskiöld. 

 24,28 mm. in length. 



The species is previously recorded from this place (Pe- 

 RACCA, loc. cit.). 



Hyla paipebrogrranulata n. sp. 



Plate 1, fig. 2, 2 a, 2 b. 



One specimen; Tatarenda, Bolivia, Chaco, Erland Norden- 

 skiöld. 1902.
