The birds from central Celebes Tvlien compared with the northern 

 birds are duller, more greenish above, especially on the pileum. It 

 may be there is more than one form of this species in Celebes, or the 

 differences may be seasonal; for the present I prefer to adopt the 

 latter supposition.

146. EUMYIAS SEPTENTRIONALIS SEPTENTRIONAIIS (Biittikofer) . 



Two males and one female, Toemaratas, July 5-9, 1916; one 

 female, Goenoeng Lehio, January 17, 1917 ; one male, Toewo Moun- 

 tain, Besoa, November 3, 1917; one male, Rano Rano, December 19^ 

 1917. 



The two males from central Celebes appear to be slightly darker 

 with smaller bills than the two northern males. The series is too- 

 small to arrive at any definite conclusions, and for the present I 

 prefer to keep them under one name. 



Stresemann^^ makes the Philippine {E. panayeiisis\ E. nigrimen- 

 talis and E. nigriloHs)^ Celebes {E. septentriondlis and E. me- 

 ridionaUs) , the Ceram {E. harterti) , and Obi (E. obiensis) species^ 

 races of E. panayensis, an arrangement which in my judgment is not 

 correct. Of E. panayensis I have seen no specimens, but of the other 

 two Philippine species I have good series and they are so different 

 from the Celebes forms that it is doubtful if they are more closely 

 related than being derived from the same stock. True, the Celebes 

 forms probably reached the island from the Philippines, but this has 

 been at so remote a period of time and the differences are so great that 

 their subspecific relationship is purely speculative. Judging from de- 

 scriptions (no specimens of E. ineridionalis have been examined) the 

 two Celebes birds are only forms of one another and should be treated 

 as such. E. panayensis ohiensis (Hartert) and E. panayensis harterti 

 (van Oort), are made races of the Philippine species by the describ- 

 ers, but this, speaking geographically, can not well be so, if we 

 recognize the Celebes forms as specifically distinct. They are, judg- 

 ing from descriptions alone, closely related to the Celebes forms of 

 which they are probably only races.
