115. Pachycephala par compar subsiiec. nov. 



Differs from 1'. jmi- as follows : Lores and an indistinct superciliary line paler, 

 more buffj', ear-coverts somewhat paler ; the abdomen is mueh paler, and some- 

 times tinged with yellow ; the throat therefore hardly at all iu contrast to the 

 abdomen ; under tail-coverts paler, more sulphur-yellow ; tail generally lighter ; 

 under wing-coverts lighter, almost whitish. Some specimens have distinct brown 

 shaft-streaks on the throat, others not. 



Hab. Letti and Moa. 



Type: No. 0033, i, Letti, 4. xi. 1902. H. Kiihu coll. 



There can be no doubt that the two new forms, par and compar, represent 

 each other, and I have therefore treated them as subspecies ; but an ultimate 

 revision of the genus will probably lead to the reception of more forms into the 

 same species. I am, however, not able to review the whole group at present. 



Mr. Kiihn sent the following specimens :

 6439.)

" Iris (? dark brown (dull blackish brown), ? chocolate-red (burnt-sienna red), 

 dark coffee-brown (dark brown), bill black, feet ash-grey, greyish plumbeous." 



110. Pachycephala arctitorquis kebirensis Mey. 



Pachycephala k-ehii-eiisis A. B. Meyer, Abh. Isis 18e:^. p. 35 (Babber). 



20 t? ad., 18 ? ? and juv., Roma, July ^August 1902. (Nos. 5014-5028, 

 5222, 5223, 5311, and twenty without numbers.) 



10 c? ad., 6 ??, Moa, November 1902. (Nos. 0114-0121, 0197—6199, 

 6258, 6259, and three without numbers.) 



1 ?, Wedan, near Babber. W. Doherty coll. 



It is with much hesitation that I enumerate the birds from Roma and Moa 

 under Dr. Meyer's name kebirensis, which he has given to the Babber form ; but 

 I am fully convinced that none of these are the true arctitoi-<]uis, which is the 

 Tenimber (Timorlaut) one only. 



Iu P. arctitorquis arctitorquis the female is above cinnamon, the crown really 

 cinnamon, the back tinged with brown, and P. a. arctitorquis is considerably smaller. 

 In the form inhabiting Dammer, which I presume to be exactly the same as that 

 from Babber (judging from the one specimen obtained by Doherty and from 

 descriptions), the crown is not cinnamon in the fully a.dn\t /emu le, but rufous-grey. 

 The Roma birds are most closely allied to those from Dammer (and Babber), but 

 the /ewz/es are mostly more gre3-ish above. lam inclined to think that they are 

 diflerent, especially as there is an evidently young Roma example with a yellowish 

 abdomen and less cinnamon above than any apparently equally young Dammer 

 examples. The tails are also purer grey, not tinged with grey. On the other 

 hand, two Dammer birds (ai)parently very adnlt /e/nales) are not distinguishable 

 from the Roma series, and the former are mostly worn, the Roma ones in 

 beautifully fresh plumage. Moreover, the worn Moa birds (collected at another 

 time of the year) look more brownish on the tails. On the other hand, the Moa 

 series is smaller, wings about 1 to mm. shorter. I defer judgment at present, 

 until fresh series from the same months of cJ and ? ad. and juv. are to hand from 

 the various islands ; but there are apparently only two possibilities : that of two or 

 that of four forms — namely, either :
