Hyla ebraccata, sp. nov. 



Of the type of H. leiicopJiyUata, and perhaps to be regarded as 

 a color variety of it. It is a very distinct one and probably 

 geographically circumscribed, and hence until intermediate forms 

 are discovered, may be considered as a species. Head broad, 

 short, lores nearly vertical. Tympanum one-fifth orl)it; skin 

 above perfectly smootli. Fingers i)almate to end of first pha- 

 lange, toes to end of second. Tongue little free behind ; vome- 

 rine teeth in fasciculi opposite anterior margin of nares. The 

 heel extends to beyond the muzzle, which marks the middle of 

 the forearm. Color above very light golden-brown ; a deep brown 

 triangular spot between the eyes, whose apex is produced back- 

 wards to a similar large spot on the back. A purplish-brown 

 band from the end of the muzzle to the end of the cocc^'x, which 

 fades below into the white of the belly. Edges of the upper lip 

 white marked; a large yellow spot telow the eye, and small yel- 

 low spots in the lateral band. On the foreleg, tlie humerus like 

 the forearm is brown above, silver spotted. On the hind leg, the 

 femur is entirely colorless ; tibia is brown with silver bands and 

 spots ; bases of all the toes colored. Fingers uncolored except 

 on the metacarpus. Belly yellow. Length of head and body 29 

 mm., width head 11 mm. Length hind leg 51 mm., to hind foot 

 22 mm. 



Hypsiboas xerophyllum, Dura. Bibr.
