ANDERSSON, BATRACHIANS FROM BOLIVIA, ARGENTINA, PERU. 15 



Tongue broad, subcircular, entire, slightly free behincL 

 Vomerine teeth in two short slightly arched fasciculi in a 

 nearly straight interrupted series partly behind tlie moderate 

 choanae. The shortest interchoanal space is 65 "/o of the 

 distance between the outermost angles of the choanse; closely 

 behind these there is a transversal palatine ridge. Snout snb- 

 trnncate, longer than the diameter of the eye ; canthiis rostralis 

 rounded, loreal region concave. Nostrils near the tip of the 

 nose; interorbital space considerably broader than the npper 

 eyelid. Tympanum very distinct, small, scarcely half the 

 diameter of the eye. Fingers webbed only at the base; on 

 the fourth toe the web reaches the penultimate phalanx, on 

 the others the disks. On the fingers the disks are somewhat 

 smaller than the tympannm, on the toes considerably so. Hind 

 limb long and slender; the tibio-tarsal articulation reaches 

 nearly the tip of the snout. Upper parts of the body with 

 distinct porous tubercles, the upper eyelid, the whole lower 

 surfaces of the body and of the thighs, and the sides of the 

 body densely granulate. A faint fold above the tympanum. 



Light brown above with large dark markings, viz. a large 

 Y-shaped spöt with the short broad branches of the Y begin- 

 ning at the eye and the narrow stem connected with another 

 large spöt, covering the whole posterior part of the back, 

 except an insuhform area of the ground-colour. Both on the 

 light and dark coloured parts there is a honeycombed net- 

 work of faint, more or less indistinct, darker lines. On the 

 parts before the dark Y-shaped spöt these lines are more 

 numerous, causing these parts to appear darker than the 

 other light ground-colour. Behind the eye a broad dark band, 

 light-edged at the upper margin, including the tympanum, 

 extends to the axilla, where it bifurcates, an upper branch 

 running somewhat further on the side of the body, a lower 

 one out on the humerus. Visible parts of the limbs, feet and 

 hands provided with broad very distinct cross-bands. Lower 

 surfaces whitish with a black shade on the belly, where the 

 white granules are encircled by narrow lines of dark ground- 

 colour. Also on the sides the granules are white and sepa- 

 rated by dark network. 



Length between nose and vent 33 mm., femur 14,5 mm., 

 tibia 16 mm., tarsus with 4th toe 20,5 mm., forearm 20 mm..
