 Janeiro. Vomerine teeth in two large, slanting contiguous patches far 

 behind and between the choanae; tongue about three-fifths the width 

 of mouth-opening, chordate, with a distinct indentation on its free 

 posterior border; snout fairly long, rounded when seen from above, 

 slanting forwards to edge of upper lip in profile, the upper jaw scarcely 

 projecting beyond the lower; nostrils lateral, their distance from end 

 of snout about one-third their distance from eye, separated from each 

 other by an interval equal to their distance from eye. Canthus 

 rostralis very sharp, loreal region flat and nearly vertical, the upper 

 lip flaring outwards below it. Eye large, fairly prominent, its diam- 

 eter 1}^ times in length of snout; interorbital diameter equal to width 

 of upper eyelid, slightly less than distance between nostrils. Tym- 

 panum distinct, two-fifths the diameter of eye, separated from eye 

 by one-half its own diameter. Fingers free, fairly long, fourth longer 

 than second, first shorter than second, all with well dilated tips; a 

 pronounced rounded tubercle at base of first finger, and a smaller one 

 on palm; metacarpal tubercles well developed; toes long, slightly 

 webbed at base, with enlarged disks, fifth slightly longer than third,

 nent, semicircular, inner metatarsal tubercle; no outer tubercle; no 

 tarsal ridges. Body fairly slender, in postaxillary region a little less 

 than greatest head width. When hind leg is adpressed, heel reaches

 elbow strongly overlap ; when hind legs are bent at right angles to body, 

 heels overlap. Skin of upper parts minutely glandular, with a 

 glandular middorsal line and fainter lateral lines; a pair of curved 

 ridges between the eyes ending in enlarged flattened protuberances 

 behind the eyes; a W-shaped glandular ridge just behind the head; a 

 few small scattered tubercles at corner of mouth below ear; a sHght 

 supratympanic ridge; venter smooth, with traces of a ventral disk;
