6 ARKIV FÖR ZOOLOGI. BAND 3. N:0 12. 



The one specimen is rather lighter than the other one; 

 botli, however, correspond compietely with the diagnosis in 

 Boulenger's catalogue. 



Previously, the species is stated to have been found in 

 Venezuela, Ecaudor and possibly in Brazil. 



Paludicola fuscomaculata Steind. 



Five specimens, 19 — 32 mm. in length; four from Tata- 

 renda, Bohvia, Chaco, April 1902. One from Casabindo, Puna 

 de Jujuy. Argentina, Okt. 1901. Erland Nordenskiöld. 



All specimens are well characterized by their well deve- 

 loped metatarsal tubercle as also by the flat, blackish brown 

 lumbar gland, encircled with a narrow white ring. The smallest 

 specimen is covered on the upper surface with numerous small 

 warts, while the other four are quite smooth. The lumbar 

 gland of the largest specimens is distinctly chagreened, not 

 or but slightty visible in the others. All the specimens have 

 on the tympanic region a semi-lunar dark spöt more or less 

 distinct, with a narrow light excavation on the lower margin. 

 In the largest specimens we find behind this spöt a dark- 

 coloured lateral band, extending to the lumbar gland. The 

 lower surface is light with small brown döts on chin and 

 throat. In the largest specimens there is a distinct ventral 

 disk, slightly visible also in two of the smaller ones.

 teeth in small groups, convergent behind from the front edges 

 of the choanse. Snout rounded, as long as the orbital diameter.
