ANDERSSON, BATRACHIANS FROM BOLIVIA, ARGENTINA, PERU. 7 



carried forwards along the body, the tibio-tarsal articulation 

 reaches the middle of the orbit or beyond. Upper siirfaces 

 smooth, except a few small scattered tubercles on the back 

 and on the hind parts of the thighs, the lower surfaces of 

 which are granular; remaining lower parts smooth. A large 

 oval lumbar gland, variable in length. In one specimen (the 

 figured one) it is once and a half as long as the orbital 

 diameter, in the other specimen on one side of the same 

 length as this diameter, on the other side distinctly lon ger, 

 thongh not as long as in the specimen first mentioned. 



Colour above grayish brown. with very distinct, large, 

 darker, lightedged, unregular spöts. Immediately inside their 

 light edges there sometimes rnns a narrow black stripe, and in 

 the spöts there are black specks that may often be seen to run 

 together into rings. On the whole, the arrangement of the 

 spöts is about the same in both specimens, but by merging or 

 dividing they get, however, differently shaped. There is a 

 faint trace of a light median line. The lumbar gland has a 

 large oval dark spöt with a broad black margin, narrowly 

 edged with white. In one example the dark spöt occupies 

 nearly the whole gland, in the other (the one with the larger 

 glands) there is a broad börder of the ground-colour encircling 

 the spöt. Loins and sides of body hght with small black spöts. 

 Limbs with broad dark cross-bands. Lower siirtaces of a dirty, 

 yellowish white; chin gray, probably a male character, both 

 specimens being males. 



Among Paliidicola-species with well developed lumbar 

 gland, hitherto known, it seems only to be P. hihronii Tschudi, 

 P. cinerea Cope, and P. brachyops — the last mentioned as 

 it is characterized in Cat. of Batr. sal. p. 282 — with which 

 this form may possibly be identical. The other species all 

 seem to have their distinct characters, by wiiich they are 

 easily distinguished from this one: P. hufonia Bell has half- 

 webbed toes. P. juscojnaculata Steind. a tarsal tubercle, P. 

 horelli Per. lacks dermal folds along the toes, P. fischeri Boul. 

 has no vomerine teeth and the first finger shorter than the 

 second, P. frenata Cope has a rudimentary second finger and 

 P. edentula Boettger also lacks vomerine teeth and has long 

 and narrow tongue. 



As to the three first-mentioned, P. hihroni has a longer 

 and more rounded nose^ the nostrils are situated nearer
