set off from the top of the head. Pupil elliptically transverse. Tympanum 

 rather indistinct, small, its rim not very prominent, its diameter equal to one-third 

 that of the eye, separated from eye by an interval equaling its own diameter. 

 Fingers free, with small lateral ridges, the tips of the three outermost dilated 

 into large disks, notched at the tips ("heart-shaped"), that of the third finger 

 about equal to the tympanic area; tip of inner finger rounded and ball-like but 

 scarcely dilated: fourth finger much longer than second, reaching nearly to base 

 of disk of third; no rudiment of a pollex, but a well-developed callosity at base 

 of first finger; subarticular tubercles on hands and feet moderate; toes free, with 

 lateral ridges, all their disks enlarged and dilated, the tips of the third and fourth 

 only bearing perceptible notches; disk of fourth toe about equal to that of third 

 finger, covering the tympanic area; fifth toe somewhat longer than third, reaching 

 to base of antepenultimate phalanx of fourth toe; a small oval inner metatarsal 

 tubercle, and a larger round, outer one; a prominent round tubercle on heel, 

 but no tarsal ridge. Body rather stout, in post-axillary region a little wider than 

 the head. When hind leg is adpressed, heel reaches to center of eye; when limbs 

 are laid along the body, knee and elbow touch; when hind legs are bent at right 

 angles to body, heels overlap considerably. Skin of upper parts heavily glandular 

 with scattered warts on the back and a row of elongated warts in the dorsolateral 

 region; a wide, low, supratyrapanic ridge; some small warts near edge of upper 

 eyelids; chin slightly granular; belly and under surface of femur very coarsely 

 granular, with a loose fold of skin bordering the edge of the granular area on 

 the femur anteriorly and posteriorly; a very distinct ventral disk; the skin between 

 this disk and the femoral granules quite smooth. 



Dimensions: Head and body, 19 mm.; head length (snout tip to posterior 

 tympanic area), 7 mm.; head width, 7.5 mm.; femur, 8 mm.; tibia, 10 mm.; 

 foot (from base of inner metatarsal tubercle), 10 mm.; hand (from base of first 

 finger), 6 mm. 



Color (in Alcohol): Dorsum light sepia; a seal brown line between the 

 upper eyelids, the area on the snout in front of this line paler; brown spots 

 encircling some of the large warts on the back; coarse brown reticulations on 

 posterior femur; venter immaculate fawn color. 



Remarks. — This small frog from the slopes of Itatiaia, presumably 

 the highest mountain in Brazil, shows a great similarity to Eleuiher- 

 odactylus unistrigatus (Giinther), Icnown only from Ecuador and 

 Bolivia. It diflPers in having wider upper eyelids and a narrower 

 interorbital space, and in having the tibia, foot, and hand longer. 

 These differences in physical proportions are best expressed by accord- 

 ing subspecific rank to the Brazilian form E. unistrigatus holti, the type 

 of which is unique.
