Table 3. Qualitative assessment of the morphological features present on unresolved museum vouchers.

A priori indicates the epithet under which each specimen is catalogued, parotoid indicates the point at which the two swollen glands of the toad are nearest to one another, crest size indicates whether the supraorbital and postorbital are uniform in thickness or the postorbital are enlarged, chest pattern is the degree to which the venter of each toad is colored, warts per spot indicates the number of large dorsal warts encircled by black pigment. Using these characteristics, we provide a qualitative assessment of the likely identity of these specimens, as well as the county, year, museum, and specimen number taken from each catalogued record. N/A indicates a lack of photographs demonstrating this feature.
