170 NOTES AND ADDITIONS. 
I am, therefore, quite aware that the list of native 
names is still subject to many errors and could certainly 
be improved upon. 
A rather amusing error was caused by my ignorance of 
the Sundanese language. The name of Irena puella turcosa 
Walden was given by me on page 138 as »doeka”, which 
in Sundanese simply means >I do not know”. 
Another difficulty which I had to encounter was that 
the native languages lack sufficient expressions for an exact 
description of intermediate colourshades. As most of the 
skins were prepared during excursions, made by my hun- 
ters to different parts of the country, and not in my 
presence, I was not able to control whether they had in- 
dicated the right colours for the feet and the bill of the 
bird, when in a fresh state. My hunters were completely 
at a loss how to describe the different shades lying between 
light gray, fleshcolour and yellowish white, which are 
shewn by the feet and bill of many birds, and which shades, 
indeed, are most difficult to describe. 
The native names of the birds and the geographical 
names are rendered throughout in Dutch spelling, except 
for the mute e, which is transcribed as @ The letter q at 
the end of a word expresses an imperfect 4. The diphthong 
eu in Sundanese names sounds like the German 6 in 
schön. 
The Malay names are ‘those of the Malay dialect of 
Batavia, and not the proper Malay of Sumatra. 
With the native themselves there prevails much confusion 
about the names of many species. The same name is in 
various districts often used for quite different birds; on 
the other hand the same bird possesses sometimes different 
names in places situated quite near together. 
In Tjabang-boengin, an isolated fishervillage at the 
mouth of the Tji Taroem in the Krawang Districts, the 
natives use for a number of species quite peculiar names. 
A few are mentioned in the list, for instance on page 107 
and 113.
