I have only obtained four specimens of this interesting species 

 on Penang, two near the great water-fall (above the Alexandra 

 bath), and two in a narrow gorge about half way up the Penang hill. 

 In both cases, the specimens were found flatly attached to the 

 side of the rock above the water, and did not make the slightest 

 attempt to escape when taken from it. This habitat seems peculiar, 

 and corresponds with that of a new species which Dr. J e r d o n 

 lately received from South India through Major Beddome 

 (vide Proc. Asiat. Soc. for March, 1870, p. 85). In general form and 

 style of colouring our species much reminds of Ixalus opistorhodiis, 

 lately described by Dr. Gr u n t h e r from a Nilgheri specimen 

 (Proc. Zool. Soc, 1868, p. 484, pi. 37, fig. 3.)
