REPTILES AND BATRACHIANS FROM TENASSERIM 483 
irregular darker cross bands; lower surfaces white, uniform or 
scantily spotted with brown. Male without vocal sacs. 
From snout to vent 56 millim.

This is the form which I have referred with doubt to Rana 
modesta, Blgr. (Cat. Batr. Ecaud., p. 25, specs. d-g.). Now that 
abundant material has come to hand, I find that it differs con- 
stantly in the blunter snout, the lesser difference in length 
between the first and second fingers, the longer metatarsal 
tubercle (it does not measure half the length of the inner toe 
in R. modesta), and the absence of vocal sacs.

= 9. Rana lateralis, sp. n. 
Vomerine teeth in two oblique series between, and extending 
to the inner anterior corner of the choane, widely separated 
from each other. Head moderate, depressed; snout as long as 
the diameter of the orbit, acuminate, slightly projecting; nostril 
equally distant from the orbit and the end of the snout; loreal 
region concave; interorbital space as broad as the upper eyelid; 
tympanum very distinct, three fourths the diameter of the eye. 
Fingers moderate, first much longer than second; toes three- 
fifths webbed; tips of fingers and toes slightly swollen; sub- 
articular tubercles small; a large, compressed, very prominent 
inner metatarsal tubercle, two thirds the length of the inner 
toe; no outer metatarsal tubercle. The tibio-tarsal articulation 
reaches the anterior border of the eye. Skin smooth; a narrow 
glandular lateral fold and another from below the eye to above 
the shoulder. Back grey, sides black, the two colours sharply 
separated on the lateral fold and on the canthus rostralis; a 
black line borders the upper lip, separated from the black loreal 
and temporal regions by a broad pure white band which extends
