In Sikhim, according to Elwes and de Niccville, it occurs from 

 quite low elevations in the Terai up to 7000 feet. Its almost 

 uniform dark colour renders it inconspicuous in the jungle, and it 

 is therefore difficult to account for its being further protected by 

 a disagreeable smell and probably taste. Wood-Mason has 

 recorded that the females have a strong and disgustingly rank 

 musky odour.
