trivirgatus (Strickland) to Phylloscopus. Acanthopneuste everetti 

 Hartert, Cryptolopha everetti waterstradti Hartert, and Oryptolopha 

 ceramensis Grant, Stresemann ^^ makes races of Gerygone glulian- 

 ettii Salvador!, which he also places in Phylloscopus. Of the latter 

 I can not speak, not having specimens, but this disposition of Crypto- 

 lopha trivirgatus is not a happy one. Bianchi ^^ has reviewed the 

 genus, but there have been quite a number of forms described since 

 that time. 



163, PHYLLERGATES CUCULLATUS RIEDELI Meyer and Wiglesworth. 



Two males, Goenoeng Kalabat, 6,600 feet, April 7 and 9, 1916; 

 two males, Goenoeng Lehio, January 15 and 19, 1917; two males, 

 Kano Rano, December 11 and 12, 1917. 



The two males from Goenoeng Kalabat have much more yellow 

 on the flanks, under tail coverts and cheeks, with a much less rusty 

 wash, than the four males from central Celebes; the latter are in 

 more worn plumage, but that would hardly account for the increased 

 rusty wash on the cheeks. It may well be that the differences are 

 geographic and that there is more than one form found in Celebes. 



The two Kalabat specimens differ from each other in the color of 

 the top of the head. One (No. 249879) has this region inclining 

 toward cinnamon rufous, shading off into a deeper color on the nape, 

 while in the other it is an ochraceous-orange. This is without doubt 

 due to fading in the latter, as it is in worn plumage, while the other 

 is in fresh plumage.
