Specimens w7ere collected at Belimbing (Legeb), Biserat, and Singapore in the botanical gardens. RANA LARIALIS Blgr. Sana labialis, Boulenger, Ann. & Mag. N. H . (5) xix. 1887. p. 345, pi. x. fig. 1 ; S. S. Flower, P.-Z. S. 1896, p. 903, pi. xiv. fig. 3 ; id. P. Z. S. 1899, p. 896. I caught a young specimen at Kwala Aring, and another nearly full-grown at the foot of Gunong Inas. RANA SIGNATA Giinther. Rana signata, Boulenger, Cat. Batr. Sal. p. 71. I caught a single young specimen of this Frog at the foot of Guuong Inas, and saw but could not catch a much larger individual in the same locality. It has not hitherto been recorded from the Peninsula, but is known in Borneo. RANA LARUTENSIS Blgr. (Plate LVII. figs. 3, 4.) Rana larutensis, Boulenger, Ann. & Mag. N. H. (7) iii. 1899, p. 273, pi. xi. fig. 1 ; S. S. Flower, P. Z. S. 1899, p. 898. These handsome Frogs are extremely common along tbe banks of the rapid jungle torrents running about the foot of Gunong Inas. They sit on the great boulders strewn along tbe courses of the streams, and when one approaches them spring boldly into the water, no matter how fiercely it may be pouring down. Soon after being disturbed they will again take up their station on the rock which they had quitted, and in such a position their colouring renders them well-nigh invisible. The tadpole is provided with a well-developed ventral sucker extending from the lower lip to beyond the middle of the abdomen. The beak is of two pieces, an upper and lower minutely serrated. The arrangement of the labial teeth is 4 5 5 1 1 4 It is thus apparently closely allied to the tadpoles of Rana jerboa Blgr., R. latopalmafa Blgr., R. cavitympanum Blgr., and Sluurois hainanensis Blgr. Coloration is much as in the adult, greenish white, mottled with dark green on tbe back ; ventral surfaces white. There are a few minute black denticles scattered on the head. Total length of the single specimen caught 65 mm., tail 45 m m. RANA LATERALIS Blgr. (Plate LVII. figs. 1, 2.) Rana lateralis, Boulenger, Ann. Mus. Genov. (2) v. 1887, p. 483, pi. viii. fig. 2 ; id.
