Show 1899.] BATRACHIANS O F T H E M A L A Y PENINSULA A N D SIAM. 897 in the Larut Hills, Perak, elevation 4000 feet, in March and April 1898. Colour. In the P. Z. S. 1896, p. 904, I described the life coloration of this species, but having since then examined more specimens I think the following account to be more complete:- Top of head and back rich dark chocolate-brown (in very small frogs of this species the back is a very bright red, more vermilion than chocolate), bordered on each side from the nose to above the vent by a very distinct line, usually all white but sometimes white only on the head, merging on the body to yellow and then orange. Sides of head, neck, and body are very dark brown or black; sometimes a very distinct line of lemon-yellow spots from behind the nostril to angle of mouth, smaller anteriorly and getting larger posteriorly; sides of the body with a few white spots in an irregular line from angle of mouth to thigh, or else extensively spotted with small white or yellow spots. Tympanum dark reddish brown, sometimes nearly black. Limbs very dark brown or bluish black, with marblings usually bluish white or very pale grey in colour but varying from white to orange ; the hands, feet, and toes may have as dark a ground-colour as the limbs and as distinct light marblings, or the black may turn to brown and the marblings be less conspicuous. Lower surfaces, chin, and throat dark brown, sometimes nearly black and immaculate (March), or dirty buff like the abdomen (Nov.); body dirty buff or dark brown mottled with yellowish buff ; limbs brown, sometimes spotted with white. Iris pale golden bronze, extensively marked with very dark brown. Size. A n adult 2 from Penang measured:-snout to vent 51 mm.; arm 30 mm.; leg 82 m m. Distribution. Malav Peninsula, Borneo. Tadpoles. Both in November 1896 and in March 1898 I found many tadpoles of this species in small ponds on Penang Hill, but none with legs developed (though in March 1896 there were tadpoles with legs and also recently transformed young frogs about, in the same locality); they agreed with those described and figured P. Z. S. 1896, p. 904, pl. xlvi., except that some had about 8 long papillae along edge of lower lip. 17. RANA GLANDULOSA Blgr. Rana glandulosa, Blgr. Cat. Batr. Sal. p. 73, pl. vii.
