Description. — Young female, USNM 98024, Agua Limpa, Ouro 

 Preto, Minas Gerais. Vomerine teeth in two short, heavy, trans- 

 verse, widely separated series behind the clioanae; tongue two-thirds 

 the width of mouth opening, almost circular, with a very slight 

 indentation on its partially free posterior margin; snout relatively 

 short, rounded when viewed from above and in profile, the upper jaw 

 extending somewhat beyond the lower; nostrils lateral, scarcely 

 projecting, their distance from end of snout about one-half that to 

 eye, separated from each other by an interval equal to their distance 

 from eye. Canthus rostralis blunt but well defined, loreal region 

 concave, nearly vertical. Eye large, promment, its diameter equal 

 to its distance from end of snout; interorbital diameter very slightly 

 greater than that of upper eyelid, slightly greater than distance 

 between nostrils. Tympanum very distinct, medium-sized, about 

 one-half the diameter of the eye, separated from eye by an interval 

 equal to its own diameter. Fingers webbed only at the base, fourth 

 much longer than second, reaching halfway on disk of thu'd which 

 covers almost the entire tympanic area; no pronounced rudiment of a 

 pollex; toes one-half webbed, fifth somewhat longer than third, disk 

 of fourth covering three-fourths the tympanic area; a pronounced 

 oval inner but no outer metatarsal tubercle; a very faintly indicated 

 ridge along inside of tarsus; no dermal appendage on heel but a distinct 

 ridge across it (often ending in a small tubercle); body elongate, in 

 postaxillary region narrower than greatest width of head; when hind 

 leg is adpressed, heel reaches to anterior corner of eye; when limbs 

 are laid along the sides, knee and elbow just touch; when hind legs 

 are bent at right angles to body, heels overlap. Sldn of upper parts 

 quite smooth; a slight glandular ridge extending along upper border 

 of tympanum and ending in front of shoulder; skin of throat and 

 chest smooth, that of belly coarsely granular, that of underside of 

 thighs more finely granular; no apparent skinfold across the chest. 

 (Apparently a median vocal sac in the male.) 



Dimensions. — Head and body 37 mm.; head length 11 mm., width 

 11 mm.; femur 17 mm.: tibia 18 mm.; foot 15 mm.; hand 11 mm. 



Color in alcohol. — Ground color of upper parts pale olive-buff; a 

 sepia stripe beginning at the nostrils, continuing behind the ear across 

 the tympanum where it is widest, then narrowing and gradually 

 fading out as it reaches the groin; a median series of drab spots 

 representing a median stripe from tip of snout to anus; on each side 

 of this a row of very small spots, then a row of large ones, then another 

 row of very small ones, so that between the sepia lateral stripes there 

 are seven alternately wide and narrow longitudmal stripes, in this in- 

 stance reduced to a series of spots ; upper surfaces of limbs with rows
