i. Hylophorbus biroi (v. Meh.). 



Phrynixalus Biroi v. Mehely, Termesz. Fiizetek, XXIV, 1901, p. 247, pi. IX, figs. 

 1—4 ( e gg s ); XI 5 fi g s - 3—5 (palate, skull); XII, fig. 2. 



Tongue very feebly nicked and half free behind. Head about 

 as long as broad ; snout obtusely pointed, about as long as 

 the upper eyelid, much longer than deep; canthus rostralis 

 strong; loreal region almost vertical, concave; nostril twice 

 as far from the eye as from the tip of the snout ; interorbital 

 space twice the width of the upper eyelid ; tympanum not 

 very distinct, about 1 / z the diameter of the eye. Disks of 

 fingers rather large, of toes smaller; first finger much shorter 

 than second; third toe longer than fifth; subarticular tubercles 

 indistinct; a large and oblong, rather indistinct inner meta- 

 tarsal tubercle; the heel reaches the tympanum, the tarso- 

 metatarsal articulation the anterior border of the eye. 



Skin smooth; lower surface granulated, at least on posterior 

 part of belly. 



Upper parts dirty pink-coloured, finely and rather densely 

 dotted or marbled with reddish brown ; a dark streak along 

 the side of the head, which may be continued along the 

 anterior part of the body, and sometimes another along each 

 side of the back; whitish or reddish yellow below, throat and 

 anterior part of breast sometimes blackish brown. Length 33 mm. 



As is stated by v. Mehely the egg-strings are deposited in 

 the water, though the development is direct; the embryo has 

 no gills, but breathes by the aid of the large tail. 



Habitat: New Guinea (Tor riv.!; Sattelberg, 750 m.).

Tongue feebly nicked and nearly half free behind. Head as 

 long as broad; snout obtusely pointed, projecting, as long as 

 the eye, longer than deep; canthus rostralis obtuse; loreal 

 region nearly vertical, almost flat; nostril nearer the tip of 

 the snout than the eye; interorbital space a little broader
