Description. — Adult female, MRHN IG 9404 Reg. 77, (type of Hyla 

 parkeriana), Alto da Serra, Sao Paulo. Vomerine teeth in two very 

 heavy but short and \videly separated transverse series at the posterior 

 level of the moderately large choanae; tongue a little more than one- 

 half the width of mouth-opening, rounded, with a very deep notch on 

 its free posterior border; snout moderate in length, rounded when 

 viewed from above, truncate in profile, the upper jaw scarcely pro- 

 jecting beyond the lower; nostrils lateral, scarcely projecting, their 

 distance from end of snout about one-third that from eye, separated 

 from each other by an interval almost as great as then- distance from 

 eye. Canthus rostralis well developed, gradually rising away from 

 middle area of head which appears concave ; loreal region slightly con- 

 cave, the area below it almost vertical to edge of lip. Eye large, 

 prominent, its diameter equal to its distance from nostrils; a low bony 

 supraorbital ridge continuing backward from the canthal ridge and 

 curving inwards to the center of the occiput; a heavy bony area from 

 there to upper tympanic region, where a small knob of bone occurs; 

 skin fairly loose and not closely involved with the bone of the head. 

 Tympanum distinct, fairly small, its greatest (vertical) diameter equal 

 to one half that of eye, separated from eye by an interval equal to its 

 own diameter; this area distinctly bony in texture and with the skin 

 involved and immovable. Fingers webbed at the base, fourth very 

 long, much longer than second, reaching to center of disk of third, 

 which more than covers the tympanic area ; a pronounced semicircular 

 excrescence on base of first finger; a faint glandular ridge set with 

 tubercles along outside of forearm, becoming more distinct on hand 

 and fourth finger; toes a little more than half webbed, fom^th ex- 

 tremely long, its disk amply covering the tympanic area, fifth slightly 

 longer than third; a small inner and apparently no outer metatarsal 

 tubercle; a distinct glandular ridge along inside of tarsus and a very 

 weak one along outside of tarsus; a shght glandular ridge marked by 

 tubercles across heel but no true dermal heel appendage. Body not 

 elongate, moderate in build, in postaxillary region much narrower 

 than greatest width of head; when hind leg is adpressed, heel reaches 

 beyond tip of snout; when limbs are laid along the sides, knee and 

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

 heels considerably overlap . Skin of upper parts very finely shagreened 

 with a few small tubercles in the center of the back, in the preanal 

 region, and on tibia; a heavy glandular fold beginning behind the eye,
