the eye, the first finger is not longer than the second, and 

 the metatarsal tubercles are considerably smaller. From P. 

 cinerea, to which it corresponds very well in locality, it seems 

 to differ, to judge from the description of this species, chiefly 

 by its indistinct tympanum, its great outer metatarsal tu- 

 bercle and by its colour. Regarding my species it is impos- 

 sible to speak either of any »indistinct dark spöts», as they 

 are very well marked and distinctly limited from the ground- 

 colour, or of any »black crescent on the inguinal gland» etc. 



We turn at last to P. brachyops Cope. With the diagnosis 

 BouLENGER in his catalogue gives of this species these exam- 

 ples agree rather well, but not with Cope's description. ^ Cope 

 points ont that his species lacks dermal folds and that the 

 first finger is shorter than the second; the colour does not 

 agree, nor does the locality, whence I do not hesitate to di- 

 stinguish it from Cope's Paludicola (Lysiris) brachyops. From the 

 specimens dealt with in Boulenger's diagnosis it differs by 

 the truncated nose, longer hind limbs and quite different co- 

 lour, besides which the patria of this one is Venezuela and 

 N. -Brazil, my specimens living in the alpine regions of the 

 Andes of Argentina. 



Hence I believe that the specimens at my disposal 

 represent a new species, which I name alpina on account of 

 its living on the treeless alpine regions of the Andes. 



Measurements of the specimens: Length of body 39,36 mm. 

 Length of femur 17,16 mm., of tibia 16,8, 16 mm., of tarsus 

 with fourth toe 26,26 mm. Length of forearm 25, 22,6 mm., 

 length of nose 5,8, 5 mm., diameter of eye 5,5, 5 mm. Breadth 

 of the head 14,8, 14 mm., of interorbital space 3,2, 3 mm. 

 Length of lumbar gland 8 — 7, 5,2 — 6 mm. 



As regards the name of Paludicola brachyops, it seems to 

 me that Cope's species by this name is not the same as 

 that spöken of by Boulenger, whence the last-mentioned 

 species ought to be named in another way. According to 

 BouLENGER it is synonymous with Paludicola elegans Steind. 

 and P. sachsii Peters, in which case the latter name may be 

 used, the name elegans being preoccupied.
