1899.] BATRAOHIAKS OP THE MALAY PENINSULA AND 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 ha^•ing 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 ; some- 

 times a very distinct line of lemon-yellow spots from behind the 

 nostril to angle of mouth, smaller anterioi'ly 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. An adult 2 from Penang measured : — snout to vent 

 6] mm.; arm 30 mm.; leg 82 mm. 



Distrihution. Malay Peninsula, Borneo. 



Tadiwles. Both in November 1896 and in March 1898 1 found 

 many tadpoles of this species in small ])onds on Peuaug Hill, but 

 none with legs developed (though in March 1896 there were tad- 

 poles 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, pi. xlvi., except that some had about 

 8 long papillae along edge of lower lip.
