fins grayish on outer portions, brownish basally, with obscurely 

 mottled appearance on spinous dorsal. Last membranes of soft 

 dorsal and anal with few small pale gray spots, also similar spots on 

 middle of caudal. Pectoral gray. Ventral whitish, gray-brown on 

 front outer portion, hind edges white. Iris neutral tint. In the 

 young examples edge of spinous dorsal and front upper edge of soft 

 dorsal maroon-color, fins blotched lengthwise with darker olive. 

 Several pale spots at bases of last dorsal and anal rays. Front 

 ventral edge and lower anal edge broadly gamboge. 

 Length 33 to 100 mm. 



Bufo valliceps Wiegmann. 



Four examples, snout to vent 26 to 40 mm. 



Hyla bocourti (Mocquard). 



Head little longer than wide. Snout rounded, little longer than 

 •eye. Canthus rostralis distinct. Loreal region slightly oblique and 

 concave. Tongue ovoid, slightly emarginate behind. Vomerine 

 teeth in two small slightly oblique groups between choanae. Inter- 

 orbital little wider than upper eyelid. Tympanum distinct, nearly 

 "half diameter of eye. Skin weakly though finely granular above, 

 belly and lower femoral region coarsely granular, Fingers very 

 slightly webbed at bases. Toes two-thirds webbed, and disks half 

 size of tympanum. Distinct fold along inner tarsal edge. Gray- 

 brown above paler or whitish beneath, in alcohol. Dull brownish 

 obscure interorbital bar, and similar band from each upper eyelid 

 down back to vent, with narrow vertebral separation. More con- 

 trasted dark brown band from each side of snout tip back to eye, 

 including tympanum and ending in groin, and narrow whitish line 

 along its entire upper edge. Length, from snout to vent, 17 mm. 



It resembles Hyla eximia Baird in having the dark lateral band 

 from snout to groin. It differs in the obscure dark dorsal band 

 each side of the vertebral line and the toes better webbed. 



Eleutherodactylus humeralis sp. nov. Fig. 2. 



Body well depressed, elongately ovoid in contour as seen from 

 above, and width slightly greater than length of head. Latter very 

 broad, well depressed. Snout flattened above, and contour as seen 

 from above broadly triangular, tip obtuse. Canthus rostralis 

 distinct. Loreal region level and oblique. Eye moderate, about 

 f length of snout, or equal to space between front eye edge and 

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

 lips moderate. Maxillary teeth uniserial, conic, mostly uniform.
