along the roadside. They were very quiet. Color in life a varie- 

 gated grayish. 



Hyla labialis Peters, from Bogota, is perhaps related, though it 

 differs in the hardly distinct tympanum being only f of eye. It is 

 also olive-green above, changing olive-green on sides with blackish- 

 brown band from snout tip through eye to middle of side, lips 

 narrowly edged brown, and sides of thighs narrowly reticulated with 

 brown. 



Hyla nehulosa Spix, from Brazil, H. depressiceps Boulenger, from 

 Ecuador, and H. phceota Cope, from Colombia, all differ in color as 

 well as having the hind edge of the tongue rounded, not notched. 



(Named for the town of Rio Bamba, the type locality.) 



Hyla quitoe sp. nov. PI. VII, upper figure. 



Body moderately broad, somewhat depressed, and width appar- 

 ently slightly less than that of head. Head broad, depressed, scarcely 

 constricted. Snout depressed, contour as viewed above rounded or 

 well convex. Eye moderate, about 1^ to snout tip. Mouth large, 

 rictus extending back slightly beyond eye. Lips as rather thin skin. 

 Maxillary teeth uniserial, uniform, pointed, conic, hidden by lip. 

 Vomerine teeth few, larger in two very short series approximated 

 between internal nares opposite their posterior portion. Contour 

 of vomerine teeth would form very obtuse angle, latter directed 

 posteriorly. Tongue rather large, ovoid, with bulge posterior, hind 

 portion free about j entire length, and hind edge entire or convex. 

 Internal nares moderately large. External nares moderately sepa- 

 rated, falling about outer third in anterior interorbital width. Can- 

 thus rostralis not very distinct. Interorbital slightly depressed. 

 Tympanum vertically ovoid, its vertical diameter about f length 

 of eye. 



Skin largely smooth above, granular below, though granules on 

 belly best defined. Lower portions of flanks, hind limbs below and 

 posteriorly, and sides of pelvis also more or less granular. Region 

 around tympanum apparently smooth. Lower surfaces of fore 

 limbs smooth. 



Limbs all slender. Fingers with distinct, though small or short 

 basal webs. First finger trifle longer than second, and swollen 

 basally as if with rudimentary pollex. Third finger longest. Tuber- 

 cles on fingers apparently little developed. All fingers and toes with 

 rounded disks moderately developed, much smaller than tympanum. 

 Toes slender, fourth much longest, about halt webbed basally. First
