Rana phrynoides. 
Vomerine teeth in small oblique groups just behind the 
choane. Head much broader than long, much depressed ; 
snout rounded, scarcely projecting beyond the mouth, as long 
as the eye ; canthus rostralis indistinct; loreal region very 
oblique, slightly concave; interorbital space narrower than 
the upper eyelid ; tympanum hidden or very indistinct, 4 to 2 
the diameter of the eye. Fingers obtuse, first longer than 
second ; subarticular tubercles small, moderately prominent. 
Hind limb short, the tibio-tarsal articulation reaching the 
shoulder or the temple, the heels just meeting when the limbs 
are folded at right angles to the body; tibia 2} to 24 times 
in length from snout to vent. Toes short, with obtuse tips, 
entirely webbed ; subarticular tubercles small, moderately 
prominent ; a feeble tarsal fold; inner metatarsal tubercle 
narrow, feebly prominent, 4 the length of the inner toe; no 
outer tubercle. Upper parts granular, with numerous small 
warts on the back, some of which may be elongate; these 
granules and warts may bear black horny spinules ; a strong 
fold across the head behind the eyes, and a very strong 
glandular fold from the eye to the shoulder; lower parts 
smooth. Dark olive above, uniform or with rather indistinct 
darker spots ; lips with or without dark vertical bars ; dark 
cross-bars on the limbs very irregular, if present ; lower parts 
whitish, uniform or throat and limbs spotted or marbled with 
blackish. Male with internal vocal sacs; during the 
breeding-season the arms are remarkably thickened and black 
horny spines form two patches on the breast and more crowded 
patches on the inner metacarpal tubercle and on the upper 
side of the two inner fingers. 
From snout to vent 110 mm. 
Yunnan at Tongchuan fu, where the species was found in 
great numbers by Messrs. J. Graham and Dymond. 
I had first referred these specimens to &. boulengeri, Gthr., 
which is ne doubt identical with the earlier 2. spinosa, David. 
I now find they differ in the shorter hind limbs, the heels not 
overlapping, in the shorter inner metatarsal tubercle, and in 
the absence of swellings to the tips of the toes.
