 de Janeiro. 



Description: Skin over fronto-parietals, upper maxillaries and nasals partly 

 pitted, not adherent to them. 



Vomerine teeth in two short, well-separated, somewhat oblique groups between 

 and slightly behind, the choanae. Tongue sub-circular, almost imperceptibly 

 emarginate, posterior border slightly free. . . . Jaw thick, sloping out below. 

 Snout rounded, about 1% times as long as the eye. Can thus rostralis distinct, 

 curved; loreal region very concave, sloping; nostril lateral, much nearer the tip of 

 the snout than the eye. Tympanum distinct, its diameter half that of the eye. 

 Interorbital space considerably wider than the upper eyeUd. 



Lateral fingers webbed at the base, 2d much shorter than the 4th; sub-articular 

 and palmar tubercules well developed. Toes % webbed; 3d slightly shorter than 

 5th; a projecting inner metatarsal tubercle. Disks unequal, strikingly smaller on 

 1st finger and toe. . , . 



Tibio-tarsal articulation barely reaching to the back of the eye. 



Skin smooth above; granular beneath and on sides, in post-axillary region, gula 

 and chest feebly so; a supra-tympanic ridge, a barely perceptible fold outlining the 

 undeveloped dorsal pouch. Lower and posterior surface of thigh granular. 



Colour: Green (apple-green) above, deeper on head and hind surface of thighs, 

 greenish-white beneath. A very striking brown pattern edged in black, composed 

 of a canthal stripe continued dorso-laterally over the eye, deflected downwards and 

 ending in post-axillary region, an arcuate frieze on the tarsus from the heel to the 

 tip of the 4th and 5th toes, with several arches, turned inwards; similar but more 

 isolated arches on elbow, fore-arm and base of 4th finger; spots on the eyelids, 

 two small ocelli behind the tympanum, near the mid-dorsal line, a few others, very 

 small and scattered, in front of and to the sides of the dorsal pouch, a short black 

 bar and small ocellus above the anus. Three small irregular spots on the legs, one 

 of them on the knee, visible from beneath. All the spots and markings brown, 

 edged in black. Alternate obhque, light-brown and white bars on the sides of body, 

 from the end of the deflected dorso-lateral line to the groin, visible from above

Snout to vent: 63 mm. Diameter of upper ej'elid: 5 mm. 



Fore Umb: 43 mm. Diameter of eye: 6 mm. 



Hind fimb: 97 mm. Diameter of tympanum (vert.) : 3 mm. 



Head length: 21 mm. Eye to tympanum: 4 mm. 



" width: 23 mm. " " nostril: 6 mm. 



Between the nostrils: 5 mm. " " tip of the snout: 8, below 9 mm. 



Interorbital space: 8 mm. 



Sex: Female, with very loose skin, especially on the sides, except over the barely 

 indicated dorsal pouch; small ovarian eggs. 



Habitat: In epiphytic bromeliad, near a mountain-brook in rain-forest, at about 

 3,300 feet. 



Remarks: Quite a number of Neotropical Hyhds with dorsal pouches have been 

 described, most of them, hke ours, from only one or two specimens. Comparison 

 with those known to us does not show our specimen as identical to any of them, 

 including those occurring in more or less the same region of Brasil. From N.
