Before examining the above series of skins, I had received 
eggs of this Spider-Hunter * from Mr. Herbert, which differed so ex- 
traordinarily from those laid by it in other parts that I fully expect- 
ed to find it different in some respects. A most careful examination 
and comparison with other series from Burma, Assam and the Malay 
Peninsula do not enable me to detect any difference between them. 
The eggs of the Siam bird are a peculiarly dead china white, 
with no trace whatsoever of the pink tinge always present to a 
greater or lesser degree in the eggs of the Spider-Hunter laid in all 
other parts of its habitat. The markings consist of tiny reddish 
specks in a very well defined ring round the Jarger end.

¢ 22 Maprit, P. Siam, 2-6.1.16. 
¢ Klong Bang Lai, P. Siam, 19.1.16. 
After an examination of a huge series of this species I am 
quite unable to recognise Kloss’ new sub-species “koratensis”. I 
have had a series of 25 Siamese birds for comparison with over 100 
specimens from more northern countries, and I can detect no differ- 
ences which are of sub-specifie value, and not due to individual 
variation. 
Kloss is perfectly correct in his description of the young 
male bird, and in pointing out that it differs from the adult female 
in having no rufous on the throat and fore neck.
