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 ha ve 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 Siarn. 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. Blyth. — 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. (c?) and 82 mm. (?) while the 

 Chieng Hai specimen has a wing measuring 93 mm. (J 1 ). On accomit of this I have 

 referred the two smaller birds as belonging to the southern race of A. magna Hodgs. 



The birds obtained during my former Expedition to Siarn 1911 — 1912 and recorded 

 under the name of A. magna Hodgs. ought to receive subspecific rank and must be called 

 A. m. aurata, Blyth. 



The young birds obtained at Koon Tan on the llth 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. 



47. Anthreptes malacensis. Scop. — The Brown-throated Sun-bird. 



Anthreptes malaccensis: Gould p. 151.

 p. 76; Williamson I p. 45; Robinson II p. 152; Robinson III p. 757. 



A few specimens of the Brown-throated Sun-bird were observed among the hill- 

 f o rests on the Tenasserim boundary during my stay at Hue Sai in January 1915. 



48. Chalcoparia phsenicotis. Temm. — The Ruby-Cheek.
