These two forms are found associated in great abundance 

 throughout the Eegion. Whilst there are numerous typical ex- 

 amples of both forms, there is also a great mass of individuals in 

 which the characters are mixed up in such bewildering confusion 

 that it would be vain to attempt to assign them to either one or 

 other of the types.

In the Malay Archipelago this is as widely distributed as the

 are with N. Boueana.
