pply equally to each.

_Cranial Osteology._--The skull of _Hyla staufferi_ is flat and longer
than wide. The premaxillary is small and bears 9 to 13 teeth (mean for
5 specimens, 11.3). The alary process of the premaxillary is small,
concave posteriorly and vertical. Ventrally, the premaxillary is united
to the prevomers by partially ossified cartilage. The maxillary is
slender and usually bears 49 to 70 teeth (mean for 5 specimens, 60.7).
The pars facialis of the maxillary is convex and less than twice the
height of the pars dentalis.

The nasal is large, rounded anteriorly, and pointed posteriorly in
dorsal view. The nasal comprises about 40 per cent of the total length
of the skull. Anteromedially the two nasals converge; posteriorly they
overlap the sphenethmoid. The nasals lack a concavity in the midlateral
surface. Dorsally, the sphenethmoid is wider than long, roughly
pentagonal in shape; the frontoparietal is elongate, narrow, and
smooth, with a small supraorbital process anteriorly. The
frontoparietal fontanelle is narrow anteriorly and wide posteriorly.
