(KU 58414). x 1.5.]

_Variation._--Adult males have snout-vent lengths from 35.3 to 44.4
mm., and adult females from 43.4 to 50.9 mm. No notable variation in
structure is displayed in the type series. In some individuals the
dark reticulation on the dorsum is faint. Juveniles in life had dorsal
colorations varying from rich brown with darker reticulations to pale
green or gray with dark green reticulations. Some adults when
collected were pale green with faint or no dorsal reticulations; later
these individuals darkened. In all specimens the anal stripe is
absent, and the flanks are heavily spotted.

_Comparisons.--Hyla charadricola_ differs from all other members of
the _Hyla bistincta_ group in the following combination of characters:
truncate snout, green dorsum, and absence of a thoracic fold. From
other hylids that occur in the same area, _Hyla charadricola_ differs
from _Hyla miotympanum_ and _H. arborescandens_, both of which are
green dorsally, by having a truncate snout and longer fingers with
less webbing. _Hyla eximia_, though green, has brown dorsal spots,
shorter fingers, and a round snout. _Hyla robertsorum_ differs in
having a round snout and brown dorsum, and _Hyla taeniopus_ is much
larger, has transverse bands on the limbs, and has extensive
