    P. Z. S. 1896, p. 203, pi. xly. fig. 2; Boulenger, Eept. & Batr. of British India, p. 460. Specimens were collected at Belimbing (Legeh), Biserat, and Singapore in the botanical gardens. Eana labialis Blgr. Bana lahialis, Boulenger, Ann. & Mag. N. H. (5) xix. 1887, p. 345, pi. X. fig. 1 ; S. S. Flower, P. Z. S. 1896, p. 903, pi. xly. fig. 3 ; id. P. Z. S. 1899, p. 896. I caught a young specimen at Kwala Aring, and another nearly full-grown at the toot of Guuong Tnas. Eana signata Gunther. Rana signata^ Boulenger, Cat. Batr. Sal. p. 71. I caught a single young specimen of this Frog at the foot of Gunong 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. Eana 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 the banks of the rapid jungle torrents running about the foot of Gunong Inas. They sit on the great boulders strewn along the 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 Rama jerboa Blgr., R. latopalmata Blgr., R. cavitympa^ium Blgr., and Staurois hainanensis Blgr. Coloration is much as in the adult, greenish white, mottled with dark green on the 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 mm. Eana lateralis Blgr. (Plate LVII. figs. 1, 2.) Rana lateralis^ Boulenger, Ann. Mus. Genov. (2) v. 1887, p. 483, pL viii. fig. 2; id.
