In life, body pale olive-tan, belly silvery white with pinkish-orange
reticulations in some specimens; tail creamy white with silvery flecks
and black or brown reticulations. In preservative, tan and
pinkish-orange coloration lost; body transparent, reticulations on tail
present.

_Remarks._--_Hyla staufferi_ was described by Cope (1865:195) on the
basis of specimens from Orizaba, Veracruz, Mexico. He described the
color pattern as "color above dark olive, with a short black bar over
each scapula, and one from eye to eye, with a trace along the coccyx."
Cope (1887:14) placed _staufferi_ as a subspecies of _Hyla eximia_, but
he did not justify his action. Guenther (1901:262) also considered
_staufferi_ to be
