I have little doubt that what may be called the "■ Common 

 Tree-frog" of Peninsular India, the Himalayas and the Malay 

 Peninsula really represents three local races of a single species. 

 These three races or subspecies may be distinguished as fol- 

 lows : — 



I. Rhacophorus maculatus (Giinther) {forma typica). No 

 parieto-squamosal arch; dorsal surface of skull smooth; skin of 

 dorsal surface of head free. Distribution. — Peninsular India and 

 Ceylon. 



2. Rhacophorus maculatus himalayensis, subsp. nov. A well- 

 developed parieto-squamosal arch; dorsal surface of skull smooth; 

 skill of dorsal surface of head free. Distribution. — 'The Eastern 

 Himala3^as, Assam, western China. 



3. Rhacophorus maculatus leucomystax (Gravenhagen). A well- 

 developed parieto-squamosal arch; dorsal surface of skull rugose; 

 skin of dorsal surface of head adhering to the skull. Distribution. — 

 Lower Burma, the Malay Peninsula and many of the Mala}^ 

 islands. 



Mr. Kemp's specimens belong to the second race. The larvae 

 of the three races are discussed below (p. 24). 



Two small specimens were taken at Kobo and a very large 

 one on the east side of the Dihang R. at an altitude of 1,100 feet. 



15. Rhacophorus tuberculatus, Anderson.

The specimens in Mr. Kemp's collection agree well as regards 

 structure and dimensions with the late Dr. Anderson's description 

 and with his t5^pe specimens, which are in the same condition as 

 they were when the species was described. The colours of the 

 latter specimens had, however, already faded at that date and the 

 fresh ones now before me are particularly interesting in this respect. 

 No two of the four brought back from the Abor country and taken 

 together in circumstances which I will describe immediately, are 

 precisely identical in colouration ; but in all the colours are so 

 blended that those commonly found on the stems of Samboos
