One specimen of a Spider-hunter was shot out of a pair one morning when I crossed 
a pass among the hills on my way up to Chieng Hai and it is with some hesitation that 
I have referred it to this species. However, it is much larger than any other specimen 
of a Spider-hunter that I obtained either in Northwestern or in Northern Siam. The 
northern form, to which I believe it belongs, is separated from A. m. aurata BLYTH. by 
having the stripes broader both on the upper and on the lower parts of the body. 
46. Arachnothera magna aurata. Brytu. — The Smaller Streaked Spider-hunter.

Birds from Koon Tan and Doi Par Sakeng are decidedly smaller than the specimen 
collected near Chieng Hai. Their wings measure 87,5 mm. (¢) and 82 mm. (@) while the 
Chieng Hai specimen has a wing measuring 93 mm. (J). On account of this I have 
referred the two smaller birds as belonging to the southern race of A. magna Hopes. 
The birds obtained during my former Expedition to Siam 1911—1912 and recorded 
under the name of A. magna Hones. ought to receive subspecific rank and must be called 
A. m. aurata, BLYTH. 
The young birds obtained at Koon Tan on the 11th of September 1914 were taken 
from the nest which was found in a very dense evergreen jungle. 
The Spider-hunters seems to be exclusively confined to the evergreen forests and 
during my journey they were never observed in other kind of jungles.

A few specimens of the Brown-throated Sun-bird were observed among the hill- 
forests on the Tenasserim boundary Hunn my stay at Hue Sai in January 1915.
