THE BIRDS OF SOUTH-WEST AND PENINSULAR SIAM. 387 



p. 487, from Malacca, is merely founded on immature specimens of 

 this form. 



Bornean birds, if different, will have to bear the name 

 Archnothera fiavigaster eytonii Salvad. (Ann. Mus. Civ. Gen. 1874, 

 p. 182.), though the name was really only applied on account of 

 Ey ton's title being a vox hyhrida.

This is a bird of very considerable rarity in the Malay 

 Peninsula and has not hitherto been recorded from Siam. We 

 possess two specimens only, one S from Telom, Perak-Pahang border, 

 and the other, § , from near Kuala Lipis, Pahang. The wings and 

 bills of these specimens are 76, 77, and 32.5, 32 mm., respectively.
