The largest specimen (from Malabar) in the Collection measures 
73 millim. from snout to vent. 
The posterior border of the fronto-parietals is produced on each 
side into a process which joins, or is connected by ligament with, the 
squamosal. The above figures show the amount of variation in the 
development of this parieto-squamosal arch, irrespective, apparently, 
of age and locality. The nasals and fronto-parietals are smooth, 
except in specimens which have the posterior arch much thickened, 
in which case that region is finely sculptured ; but the skin never 
adheres to any part of the skull. The fronto-parietals are broadest 
in front, and the postorbital processes merely indicated. 
Disk of third finger two fifths to one half the diameter of the eye. 
The tibio-tarsal articulation reaches the eye or between the eye and 
the tip of the snout. Interorbita! space once to once and one third 
the width of the upper eyelid. 
Upper parts variously spotted, never banded; hinder side of 
thighs with large yellow spots, usually separated by a purplish- 
brown network. 
Hab. Indiaand Ceylon. Specimens in the British Museum from 
Ganjam, Madras, Bombay, Salem, Malabar, Nilgherries, and Ceylon. 
According to Nevill, R. maculatus is found in the hot dry parts 
of Ceylon, from Putlam, across the island, and south to Batticaloa ; 
it has a peculiar fondness for houses. Thurston (Cat. Batr. S. Ind. 
1888) remarks that it is common in Madras at night, adhering to. 
walls and windows, and is known among Europeans as the “ chunam 
frog,” from the frequency with which it is found on chunam (shell- 
lime) walls.
