The largest specimen (from Malabar) in the Collection measures 

 73 inillim. 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 scul[)tured ; but the skin never 

 adheres to any part of the skull. The fronto-parietals are broadest 

 in front, and the postorbital processes meiely indicated. 



Disk of third finger two fifths to one half tiie diameter of the eye. 

 The tibio-tarsal articulation reaches the eye or between the eye and 

 the tip of the snout. Interorhita: space once to once and one third 

 the width of the upper eyelid. 



Upper i)arts variously spotted, never handed ; hinder side of 

 thighs with large yellow spots, usually separated by a purplish- 

 brown network. 



Hab. India and Ceylon. Specimens in the British Museum from 

 Gaujam, 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.
