PLimnodytes? phyllophila, Jerdon, Joiirn. As. Soc. Beng. 1853, 

 p. 532, and Proc. As. Soc. Beng. 1870, p. 85. 



Tongue with a free pointed papilla in the median line ; fingers free ; 

 toes nearly entirely webbed ; discs small ; a small inner metatarsal 

 tubercle. Colour and markings (of spirit specimens) : brownish above, 

 with a few indistinct darker markings ; loreal and temporal regions 

 dark brown ; limbs cross-barred ; lower surface of hind limbs, hinder 

 sides of thighs, and sometimes hind part of belly beautifully rose- 

 coloured. 



For the following note on living specimens of this species, I am 

 indebted to Mr. J. R. Henderson : " Colour of upper surface dark- 

 brown, lighter on the sides ; under surface yellowish with a series of 

 dark mottlings, which almost entirely cover the throat, and render it 

 dark. Lower surface of the hind limbs rose-coloured ; anal region black. 

 A very conspicuous black band on each side of the head under each eye 

 and nostril, and continued in some specimens into the forelimb. A few 

 whitish tubercles occasionally present on the sides. Two longitudinal 

 folds always present on the trunk, and a few indistinct wrinkles on the 

 head, back, and hind legs. 



Common in densely wooded sliolas near Kotagiri (6,000 feet), and 

 at Rungaswamy's pillar. Lives in the margins of shaded streams, and 

 takes freely to the water." 



It is possible that this species is the same as Jerdon's Limnodytes 

 2jhijllophiIa, — n.s., which is described {Journ. As. Soc. Beng. 1853, 

 p. 532) as a small frog with the sub-digital discs very slightly dilated ; 

 toes not quite completely webbed; tympanum small; reddish yellow, 

 with the sides of the face dark purple ; found in all the western forests 

 among decayed leaves. 



Specimens in the British Museum from the Nilgiris and Malabar ; 

 in the Madras Museum from Kotagiri (6,000 feet) : length of body l-^ 

 inch, hind leg If inch.
