on hands very well developed, those on feet much less so ; a small inner 

 metatarsal tubercle, but no outer one. Tibio-tarsal articulation 

 reaching the axilla. Skin smooth above and beneath; a fold from 

 posterior corner of eye, widening greatly behind the arm and extending 

 to the groin, curving in towards the back in its posterior part, widen- 

 ing untn it suggests a heavy gland. 



Dimensions. — Head and body 25.5 mm.; head length 6 mm., width 

 7 mm, ; femur 8 mm. ; tibia 9 mm. ; foot 8 mm. ; hand 6 mm. 



Color in alcohol. — Dorsum nearly uniform drab, with a few slightly

mottlings ; venter drab, with more or less regular round light spots on 

 belly and throat. No vocal sac in this specimen. 



Remarks. — This species is known from Paraguay and Mato Grosso 

 as well as from Goids. Intensive collecting will undoubtedly extend 

 its known range still farther.

Eyes 1% times into the snout; the can thus rostralis evident, forming a perfect 

 acute angle; eyelids convex, projecting. A tympanic fold extending to the articu-

 arm longer than forearm. When leg is stretched forward, tibiotarsal articulation 

 does not reach the tympanum. The subarticular tubercles indistinct. Skin 

 smooth; metatarsal tubercles indistinct; neck without transverse skinfold; color, 

 dark like that of a dry leaf, cinereous on upper surface; iris black; sides and
