rupted, the three inner broadly interrupted and very short, 

 decreasing in size towards the mouth, the innermost row is 

 sometimes very small and inconspicuous ; lower lip with three 

 series of teeth, the two outer uninterrupted, tiie third narrowly 

 interrupted, the three rows are about the same length, but the 

 median is the longest and the outermost the shortest. 



The colour of these tadpoles in life is brick-red above, and pale 

 yellow beneath, but the whole skiu is very transparent, llie eyes 

 and the intestines being clearly seen. On the back on each side 

 behind the eyes is a patch of granulated skin ; in some specimens 

 there is a similar strip on the hinder part of the back on each side 

 parallel with the tail, and a large patch ou each side of the belly, 

 oblong in sliape, and each converging together towards the tail. 



A good specimen measures 37 mm. in total length ; body 15 ; 

 width of body 10 ; tail 22 ; depth of tail 6. 



Depth of muscular portion of tail at its base between 3 and 4 mm. 



The above measurements are talien from a spirit-specimen.

This handsome little Frog appears to have hitherto only been 

 recorded from Borneo; in March 1890 I found it common about 

 certain small ponds on Penang Mill at an elevation of 2000 feet. 

 They were generally in long grass near the water's edge ; wiien 

 alarmed they would jump into the water, but before long crawl out 

 again. 



Colour (from life).— 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 the insertion of the hind leg by a very distinct wliito 

 lino. Sides of head, neck, and body are very darlj browu or black. 

 The tympanum is dark reddish-brown. Along the lower part of 

 the sides of the body are a few white spots in an irregular line 

 from angle of mouth to thigh. Lower surfaces — chin and thi-oat 

 dark brown, remainder dirty buff, darker on limbs. Limbs very 

 dark brown or bluish-black, with bluish-white or very pale grey 

 marblings ; the black turns to brown on the toes, and the marbling 

 is also less conspicuous on the feet. 



These colours seem permanent and not variable according to 

 surroundings, as is the case with many bntrachians. 



Adult specimens are 45 to 50 mm. from snout to vent.

Tadpole, " Koldok-ilsan " (Malay). In March 1896, in a pond 

 of clear water (2200 ft. elevation) in the jungle on Penang Hill, 

 there were a large number of tadpoles of this species and little 

 frogs just leaving the water.
