Telmatobius duseni n. sp, 



Vomerine teeth in two slightly separated, small, but 

 distinct groups behind the choanse, which are moderate. 

 Tongue large, round, a little broader than long, not nicked 

 behind. Head short, flattened; snout short, rounded, longer 

 than the diameter of the eye; nostril midway between the 

 eye and the margin of the tip of the snout. Canthus rostra- 

 lis indistinct. Interorbital space as broad as, or broader, 

 than the upper eyelid; no tympanum. Fingers narrow, rather 

 long, free, the first not reaching as far as the second. Toes 

 one third to scarcely halfwebbed; the formula for the deve- 

 lopement of the web is: 



—_ 2,5 3 3—3,8 M 



1,5' 1,8—2' 2—2,5' 3—3,8' ^^ 



(the figures indicate the number of joints free from web, if 

 counted from first to fifth toe). If the length of the tibia 

 is marked off from the knee forwards along the body, it 

 reaches the front of the eye or the nostril. An oval inner and 

 a small outer metatarsal tubercle (the latter not discernible 

 on the right side in the largest of the specimens).
