eyes neither particularly large nor protuberant; diameter of eye equal 

 to distance from eye to tip of snout; nostrils very near tip of snout; 

 interorbital space equal to about 1% times the diameter of eye; no 

 external tympanum discernible; upper eyelids, top of head, and dorsum 

 smooth. The urostyle, vertebrae, and frontoparietal bones bright green 

 and show clearly through the pale whitish skin of back; the green limb 

 bones of hind legs plainly seen from ventral surface. No green discerni- 

 ble through skin on front limbs or pectoral girdle. Well-developed 

 disks on all fingers and toes. Fingers, except first, not particularly 

 slender; with but the merest rudiment of a web; first finger pro- 

 nouncedly shorter and more slender than second; fingers 3-4-2-1 in 

 order of decreasing length. A pronounced rudiment of a pollex. Toes 

 moderately slender, all fully webbed except fourth, which is webbed 

 to penultimate phalanx and has a margin of web to disk; toes 4-3-5-2-1 

 in order of decreasing length, toes 3 and 5 being nearly subequal. 

 Heels slightly overlapping when legs are flexed with femora held at 

 right angles to the body; knee and elbow slightly overlapping when 

 limbs pressed along the side; heel extending to middle of eye when leg 

 is pressed along body. No patagium present. Chin, vocal pouch, 

 venter, and underside of thighs rugose. External vocal pouch a longitu- 

 dinally folded structure that extends from a horizontal fold at level of 

 angles of jaws posteriorly to another horizontal fold at level of axillary 

 region. No well-developed dermal anal flaps. Tongue broadly cordate, 

 slightly free and slightly notched behind, its width about four-fifths 

 the width of mouth. No vomerine teeth. Internal nares moderate in 

 size and well separated. 



Dimensions. — Head-body length, 15.8 mm.; head width, 5.5 mm.; 

 tip of snout to posterior margin of eye, 4.2 mm.; diameter of eye, 

 2.3 mm.; hind leg (vent to tip of longest toe), 24.1 mm.; hind leg 

 (vent to heel), 13.2 mm. 



Color in alcohol. — Ground color creamy white. Small clusters of 

 pigment cells make a number of reddish spots on top of head, dorsum, 

 and dorsal surfaces of shanks. A reddish brown stripe from tip of 

 snout through nostril to eye. In this specimen, after nine months 

 in preservative, there is but the faintest suggestion of a continuation 

 of this stripe through the eye and posteriorly in the form of a dorso- 

 lateral stripe. As mentioned above, the green bones of the axial skele- 

 ton show through the skin of the back. 



Variation. — In all four of the paratypes in the collections of the 

 University of Florida the bright green frontoparietal bones of the 

 skull and the green vertebrae show clearly through the milky white 

 skin. All of these paratypes (three males, one female) have the dark, 

 rusty red spots on the back, although there is variation in conspicu- 

 ousness. In one male, particularly, the spots either are not fully
