THE BIRDS OF BANGKOK. 75 
sift these variations, and the Siamese names given in this paper are, 
it is believed, those by which the birds concerned are generally known 
in Bangkok. In this matter, and in the orthography of the words, 
I have received most valuable aid’ from H.R. H. Prince Chandaburi 
and H. H. Prince Bidyalankarana, to whom my grateful thanks are 
tendered. 
In transliterating Siamese names, for the purposes of this paper, 
aspirated consonants are represented by the correspending unaspirated 
letters, followed by an f,—thus the aspirated /& is written kh, the 
aspirated ch is written chk, and soon. In the case, however, of the 
aspirated p and ¢, an apostrophe (’ ) is introduced between the letter 
concerned and the accompanying kh —as ph and th, to avoid 
the possibility of the ph or th being pronounced like an f, as in the 
English word pheasant, or like th, as in the English words then, thin, 
&c. All vowels are to be pronounced as in Italian, and long ones are 
marked with a stroke over them—thus a. For the transliteration of 
the names, I alone am respensible. 
The accompanying plate shows the diagram of a bird, with the 
names of the various parts of its body and plumage. Most of the 
terms need no explanation, but the following definitions may be 
useful :-— 
Lores. Space in front of the eye. 
Primaries. Outermost 9 or 10 quills of the wing. 
Secondaries. Quills springing from the radius and ulna. 
Supercilium. Space between the eye and the crown. 
I have again to express my great obligations to Mr. H.C. 
Robinson, Director of Museums, Federated Malay States, for his 
kindness in identifying, or confirming the identification of, the birds 
mentioned in this paper.
