A Review of the Frogs of the Hyla bistincta Group
註釋A Review of the Frogs of the Hyla bistincta Group by William Edward Duellman is an intensive, scientific look with photos of a new species of frog. Excerpt: "The five species comprising the Hyla bistincta group are moderate-sized hylids having rather blunt heads and robust bodies. The fingers are long and have little webbing (Fig. 1). The skin of the dorsum is thick and glandular, but not tuberculate. An anal sheath is present. The skull is rather broad, flat, and solidly roofed. The ethmoid is broad, curved downward laterally, and solidly sutured to the frontoparietal. The nasals are broad, sutured for their entire width with the ethmoid, and broadly in contact medially."
