"This specimen, the second known, differs considerably in colour 

 from the type collected on Bukit Besar, in the Native State of Jalor, 

 considerably to the north of Pahang. The following notes were taken

 skin of belly shagreened. A large cream spot beneath the eye. Pupil 

 horizontal, iris mottled golden. Apparently little power of colour 

 change." — H. C. R.]
