Paludicola borelli Per. 



Five specimens from La Paz, Bolivia, and eleven from Guaqui, Peru. 



The specimens are kindly determined by Dr. G. A. Boul enger. 

 They agree completely vvith the specimens from Casabindo (Puna de Jujuy. 

 Andes of Argentine), in Arkiv för Zoologi, Bd. 3, Nr. 12, 1906 described 

 by myself as a new species, Paludicola alpin a, which species, 

 thus, is not to be maintained.

23 specimens from several localities in Peru and Bolivia, among 

 which there is a beautiful variety from Arapa, Peru, 4500 m above the 

 sea-level, tbat I bave not seen described. All the five specimens from 

 this latter locality are distinguished in having the warts very closely 

 arranged and ending in obtuse horny tubercles instead of acute spines. 

 The large black spots that generally appear in the typical form are 

 wanting ; a distinct light median dorsal stripe runs from the tip of the 

 snout to the vent ; the ground colour above brown with dark warts, 

 sometimes small light spots on the sides of the dorsal stripe. 'Che foot 

 with 4 th toe is shorter than in the typical form. As all specimens 

 from this locality, the large as well as the small ones, are of the same 

 appearance, and as I have not found one like these among all the 

 specimens of this species 1 have seen, I think it possible that they may 

 represent a constant colour-variety, which I will name arapensis. 

 Of the three varieties Werner establishes in Fauna chilensis the 

 variety ornata seems also to have a light dorsal band, but the figure 

 Werner gives does not agree with my form. 



Length of the variety arapensis 25 — 43 mm between nose and vent.
