_Diagnosis._--Small frogs (Male to 29 mm., Female to 31.6 mm.);
dorsolateral stripes irregular; paravertebral stripes usually broken;
two or three transverse bars on shanks; thighs spotted or not; arms
usually barred; interorbital bar usually present; toes about three
fourths webbed; color brown, tan, or olive-green.

_Variation._--Three hundred and sixty males chosen at random from
throughout the range have snout-vent lengths of 20.7 to 29 mm. (25.9
mm.). The smallest individuals are from Costa Rica and Nicaragua (means
24.2 and 24.4 mm., respectively). The largest individuals are from
Guatemala and El Salvador (mean of each 27.0 mm.). The ratio of the
diameter of the tympanum to that of the eye is more than 60 per cent in
most samples, but in those from Costa Rica and British Honduras it is
smaller. The color pattern is highly variable. Some specimens are dark
brown or pale brown in color. Incomplete dorsal stripes are present in
94.6 per cent of the specimens, and transverse bars are present on the
shanks in 98.3 per cent of the specimens. The interorbital spot varies
from transverse to longitudinal in position, and an irregular white
line extends from the upper jaw to the arm in some specimens (Table 7).

_Distribution._--_Hyla staufferi staufferi_ inhabits savanna and
subhumid and xeric forests in the lowlands and moderate elevations from
southern Tamaulipas southward to Nicaragua on the Caribbean versant and
from Guerrero, Mexico
