Morphology

The following is from a description of Rana aequiplicata by Boulenger (1900):

Vomerine teeth are in two short oblique series, commencing from the inner front edges of the choanae. Head is moderate, as long as broad or a little longer than broad. Snout is pointed, longer than the diameter of the orbit. Canthus rostralis is distinct; loreal region is deeply concave. Nostril is equidistant from the eye and the end of the snout. Interorbital space is nearly as broad as the upper eyelid. Tympanum is distinct, measuring two-thirds or three-fourths the diameter of the eye. Fingers are moderate, obtusely pointed; the first does not extend beyond second. Toes are broadly webbed; web reaches the extremity of the third and fifth toes, leaving two phalanges of the fourth toe free. Subarticular tubercles are moderate. A very small, oval, inner metatarsal tubercle is present; no outer tubercle is present. The tibio-tarsal articulation reaches far beyond the tip of the snout. The tibia is more than two-thirds the length of head and body. This skin is more or less distinctly granular above, with numerous, interrupted, glandular, longitudinal folds on the back. A glandular fold is present from beneath the eye to the shoulder. Males have two black external vocal vesicles projecting through two slits below the lower jaw.

Dorsum is olive-brown, with small dark spots. A broad whitish or pink vertebral band may be present. A dark cross-bar is normally found between the eyes. A black cantlhal streak and a black temporal spot are present. The tympanum is reddish brown. Limbs have dark cross-bars; hinder side of thighs are black, spotted or marbled with white or pink. A series of black spots are present on the lower jaw. The throat and belly are yellow, immaculate.
