Note. — Tbe descriptions of Daudin differ iu some important points from the species 

 of Major Lo Conte. • 



Tibia less than half the length of body, longer than arm from elbow, 

 which again exceeds hind foot. Skin nearly smooth above 5 above wood- 

 brown, with a darker interocular, triangular blotch, aud a subcuneiform 

 one on the back, couflueut in the center, A narrow line from the snout 

 to the eye. A dark vitta from the eye, indistinct in the middle, passing 

 through and involving the whole tympanum ; the upi^er edge of this 

 continued to the hind legs, the lower ceasing at the fore legs. Poste- 

 rior face of the thighs dark brown, with circular yellowish- white spots. 

 No light spot under the eye, nor any white line along the jaw 5 merely 

 a lighter shade of the ground color. 



Head broader than long. Body short, rather broad, and the entire 

 appearance as to pattern of color and shape not very dissimilar from 

 Hyla versicolor, from which, however, it is readily distinguishable by 

 the femoral yellow spots ; the dark postocular vitta, the absence of 

 light spots under the eyes. The tongue is large, ovate, slightly notched, 

 and free behind. The teeth are in two approximated minute circular 

 patches between the posterior nares. The tympanum is small, scarcely 

 more than half the diameter of the eye. The tibia is not half the length 

 of the body. The skin above is slightly pustular, although at consid- 

 erable intervals, and much less in proportion than H. versicolor. The 

 whole inferior surface of the head, body, and thighs is granulated, 

 including the throat. The pectoral fold of skin is smooth. The fingers 

 are slightly webbed at the base, the fourth longer than second. The 

 last two joints of the toes are free; the web not extending as a margin 

 to the disk of the longest toe, as in H. versicolor. 



General color above bark-brown, variegated with darker; beneath 

 dull white. A triangular blotch between the eyes, the angle behind 

 the anterior edge extending across between the middle of the edge of 

 the upper eyelids. In H. versicolor this blotch is almost always inter- 

 rupted iu the median line. On the anterior half of the back is another 

 large blotch, sending out two branches anteriorly and posteriorly, and 

 one on each side, the anterior pair sometimes running into the blotch 

 on the top of the head. Behind this are several other blotches of irreg-
