largest is about 45 mm. long. Young examples show several whitish 

 spots in a streak, due to the fold extending down from the lower 

 edge of tympanum towards shoulder. 



Three more example^ with the same data differ from all the others 

 in the median narrow whitish line extending from the snout tip to 

 the vent. This line is clearly defined in all three. Many other of 

 the specimens show a trace of it on the upper lip at the snout tip,, 

 but soon fading out in the darker color of the rest of the upper surface 

 of the snout. These examples are thus strikingly like Boulenger's 

 figure of Hylodes unistrigatusJ 



Two other examples in the collection are likely identical. One 

 was secured at Hacienda Jalancay near Chinchi, in Chimbo, April, 

 1911. The other is young, and was taken at the camp near the 

 junction of the Chiguancay and Chanchan Rivers. 



Hylodes pagmae sp. nov. PI. VIII, upper figure. 



Body moderately depressed, elongately ovoid in contour, and 

 width a little less than that of head. Latter moderately broad, a 

 little' depressed, scarcely constricted. Snout slightly depressed^ 

 contour as viewed above rather triangular, tip obtuse. Eye rather 

 large, Ij in snout or equals space between front of eye and nostril. 

 Mouth large, rictus falling about opposite hind edge of eye. Lips 

 thin. Maxillary teeth fine, uniform, uniserial. Vomerine teeth in 

 two large patches, approximated until directed posteriorly behind 

 internal nares. Tongue apparently ovoid (distorted), last third 

 free, hind edge rounded. Internal nares moderately large. External 

 nares fall at third in antero-interorbital space as viewed in front. 

 Canthus rostralis not very distinct. Interorbital depressed, twice 

 width of upper eyelid. Tympanum trifle ovoid, its vertical diameter 

 1^ in eye. 



Skin largely smooth. Belly, lower sides and lower surfaces of 

 femoral regions granular, though granules apparently rather obsolete. 

 Region around tympanum smooth. Lower surface of fore limbs and 

 throat smooth. No fold across breast. 



Limbs all slender. Fingers and toes without any webbing, and 

 if ever present only slightly developed. First finger trifle longer 

 than second, and slightly swollen basally on inside, as if with rudi- 

 mentary pollex. Third finger longest. Tubercles on phalanges 

 not well developed. All fingers and toes with terminal rounded 

 disks, moderate in size or all much smaller than tympanum. Toes
