HYLA. 269 
Light grey, with five darker longitudinal bands, the median of which expands anteriorly 
so as to form a large subtriangular spot between the eyes; femur with one, tibia with 
three cross-bands; concealed surfaces unspotted. (After Cope.)

Hab. Panama (Werner), Chiriqui (Peters).—Cotomsta, Turbo (Cope), Bogota (Peters). 
Vomerine teeth in two transverse series between the large choane. Head broad, 
depressed, with rounded canthus rostralis. Tympanum more than half the extent of 
the eye. The three outer fingers slightly webbed; nearly three phalanges of the fourth 
toe free, the web, however, margining the outer side. The tibio-tarsal articulation 
reaches well beyond the end of the snout, when the hind limb is carried forwards. 
Upper parts smooth ; a strong fold from the eye over the tympanum. Brownish-olive 
above, with a longitudinal band or series of spots on the back, bifurcating anteriorly ; 
a spot on the coccyx and near the vent brown. Upper jaw, postorbital region, and the 
margins of the upper eyelid and of the limbs white. A dark band along the canthus 
rostralis is continued over the tympanum to the scapular region; femur with narrow 
cross-bands and with the hinder side reticulate or uniformly coloured; tibize more 
broadly cross-banded; sides with brown vermiculations; lower parts whitish. Male 
with an unpaired vocal sac. (After Cope.)

The descriptions of other authors who believe that they have recognized Cope’s 
species differ in several noteworthy particulars. Thus, Peters states that “the tympanum 
is scarcely visible, its diameter being two-fifths of the diameter of the eye”; the web 
between the toes is deeply excised, but ‘‘ otherwise nearly complete, only the last 
phalanx of the fourth toe being free.” On the other hand, Werner describes the 
tympanum as “equal to ¢ of the diameter of the eye. Fingers with 4, toes with nearly 
complete webs”; he also ascribes to this species a tarsal fold.
