These two birds are larger than the Indian form, E. 0. 

 honorata, and the female has the top of the head rufescent, 

 while by far the greater number of the pale markings on the 

 upper parts are also rufescent ; the under parts are black 

 and buff. 



I am indebted to Mr. W. J, F. Williamson for the infor- 

 mation that the wings of birds in his collection from central 

 and eastern Siam range between 203 and 221 mm. in the 

 case of adult males and 198 and 215 mm. in females. 



The first race geographically adjoining honorata to be 

 separated on account of larger size was malayana Cabanis, 

 of Sumatra, which Hartert, in his " Notes on the Genus 

 Eudynamis" (Nov. Zool. x. 1903, p. 235) considers to 

 extend north to Teuasserim. 



Ingram has recently described from Hainan, on account 

 of its slightly smaller size, a pale form like E. 0. honorata, 

 under the name of E. 0. harterti (Nov. Zool. xix. 1912, 

 p. 279). Before this name is further used, however, Hainan 

 birds should be compared with specimens from Canton, 

 since to birds of this locality the name chinensis has been 

 given by Cabanis and Heine (Mus. Hein. iv. 1862, p. 52, 

 note).
