nearer to the muzzle than the eye. Canthus rostralis distinct; loral 

 region concave. Tongue heart-shaped, free behind. Vomerine teeth 

 in two small groups just behind the level of the choanae. Inner nares 

 more widely separated than the outer. Tympanum small, hardly visi- 

 ble. Body very slender. Limbs slender and weak. Fingers longer 

 and more slender than usual, the third especially long; web wanting 

 between the first and second fingers, almost imperceptible between the 

 others. Toes also long and slender; webs very small, minute between 

 the first and second toes and only reaching to the base of the antepenul- 

 timate phalanx of the fourth toe. Disks at tips of digits only moder- 

 ately large. Skin mostly smooth above, granulate beneath and on 

 sides. Palms with a few small tubercles, and one large one. Base of 

 first finger with a tubercle. Soles smooth with a well-developed tuber- 

 cle at the base of the first toe and a minute one at the base of the fourth 

 aad fifth, the latter sometimes wanting. 



Color. — Above some shade of gray or brown, with narrow lines of 

 dark brown or black, the principal of which are disposed on the back 

 in the form of a large letter X; yellowish beneath. The ground color 

 is usually pale brown. The anterior arms of the X-shaped mark con- 

 verge from just behind the eyes to the middle of the back, where they 

 meet; from this point the two posterior arms diverge posteriorly and 

 ventrally. Another mark behind this sometimes resembles an inverted 

 letter V. A dark band, well defined above but fading into the ground 

 color below, extends along the side of the snout to the anterior border 

 of the eye. A wider band, which includes the tympanum, extends 

 from the posterior border of the eye toward the base of the anterior 

 leg. Two lines, one above each eye, sometimes unite across the median 

 line and form a triangular spot. Iris golden, pupil black in life. The 

 legs above are like the back in color and are banded with brown, two 

 or three wide bands occurring on the femora and on the tibiae. A 

 dark line is generally present on the posterior surface of all the legs. 

 A dark spot overlies the vent. Body and legs uniformly oale beneath, 

 or with the throat yellowish, speckled with dusky. (G. /man.)
