limbs) are light brown with little pattern except
for narrow dark crossbars on the thighs
and faintly indicated lumbar ocelli. The postocular
and subocular markings are dark
brown, the loreal region paler. The chin is
grayish white spotted with darker gray. The
abdomen has a yellow-gold tint, and the
shank has a gray network over the yellowish
background.
VARIATION IN TYPE SERIES: The largest
specimens are a female and a male, both
adult, and both measuring 29.6 mm SVL;
four other adult females range down to 24.2
mm. Males 18.9 and 19.8 mm SVL appear
to lack vocal slits, whereas all specimens
20.1 mm or longer have them, suggesting
that males may become mature at about 20
mm SVL. Body proportions are summarized
in table 6, and regression statistics are presented
in table 7.
The color and pattern description of the
holotype fits many of the paratypes almost
equally well. Other paratypes vary from this
description. These individuals are darker, especially
in the head region, have a generally
darker ground color on the back, and may
have the abdomen mottled rather than clear.
Some have additional dark markings, such as
a canthal stripe, a W-shaped mark in the
scapular region, and spots on the posterior
back. Two of the 40 specimens examined
