Show 896 MR. STANLEY S. FLOWER ON THE [NOV.14, from Burma and Southern China, I obtained many specimens near Jenan and Alor Star, Kedah, in June 1898, and near Sapatoom, Bangkok, Siam, in August 1898. Habits. In each case they were living among swampy paddy-fields ; they sat in the grass on the ridges between the submerged fields, and as one walked along took great leaps away into the water, which, however, they did not seem to like, as they nearly always at once swam back to the bank. They are remarkably nimble, active frogs, and specimens I had in captivity used to climb up a vertical surface of glass like a true tree-frog. Colour (in life). Above rich dark brown, spotted with black, and in some individuals mottled with dull yellow and vivid green, with five very distinct longitudinal lines, which are white with golden shades (the centre line is from the snout to vent, the next pair from the upper eyelids to the sides of the vent, and the outer ones from the tympanum to the inset of hind leg). Below, head and body white, limbs yellowish. Upper surface of limbs reddish yellow, handsomely marked with dark brown, three lines along the back of the thigh being most conspicuous. Iris golden. Size. Snout to vent 38 m m . ; hind leg 63 m m . Distribution. Burma, South China, Siam, Malay Peninsula. 14. RANA NIGROVITTATA (Blyth). Rana nigrovittata, Blgr. Ann. Mus. Genova, (2) xiii. 1893, p. 334, pl. viii. fig. 3. This species, not hitherto recorded from Siam, I found very numerous along the banks of the river at M u o k Lek in the Dong Phya Fai, elevation 900 feet, in November 1897 ; both during the heat of the day, in the afternoon, and in the evening they kept up a continuous, loud and rather musical croaking, something like that of Rhacophorus leucomystax, only the note is louder and uttered much more often. They were very active. Size. The largest specimen caught measured from snout to vent 58 mm. Distribution. Burma, Siam. 15. RANA LABIALIS Blgr. Rana labialis, Blgr. Ann. & Mag. Nat. Hist. (5) xix. 1887 p. 345, pl. x. fig. 1; S. Flower, P. Z. S. 1896, p. 903, pl. xiv. fig. 3 (tadpole). In Sept. 1898 in Singapore I saw several specimens of this frog both in the Botanical Gardens and in the jungle on Bukit Timah ; it was in each case observed sitting on the leaves of plants or in bushes, so evidently is not a true water-frog like R. eryihrcea. Rana labialis can change its colour rapidly from green to brown. Distribution. Malay Peninsula and Mentawei Islands. 16. RANA LUCTUOSA (Peters). Rana luctuosa, Blgr. Cat. Batr. Sal. p. 68. Localities. Common on Penang Hill, elevation 2000 to 2200 feet (Nov. 1896 and March 1898), and obtained by Mr. A. L. Butler |
