a. S' Mouth of the Mimika River, 21st March, 1911. 

 [No. 1220, C.H. B. G.] {Type of the species.) 



This species is most nearly allied to P. monacha G. R. 

 Gray, but the upperparts are uniform deep black instead of 

 dull brownish-black. Iris brown ; bill black ; feet dark ash- 

 colour. Total length ca. 160 mm. ; wing 92 ; tail 65. 



Count Salvadori, has examined the type of P. lugubris 

 Miiller, from the Utanata River, and considers it synonymous 

 with P. monacha [cf. 0. P. ii. p. 233 (1881)].

This dark brown species, described from specimens pro- 

 cured by A. S. Meek on Mt. Goliath, is new to the British 

 Museum. 



Like P. gamblei, this is a somewhat aberrant species of 

 the genus Pachycephala, the wings and tail being rather soft 

 and rounded. 



Pachycephala leucostigma. (PI. IV.) 



Pachycephala leucostigma Salvad. 0. P. ii. p. 234 (1881) ; 

 Roths. & Ilartert, N. Z. x. p. 107 (1903), xiv. p. 473 

 (1907), XX. p. 509 (1913).

This male agrees with the description of the adult male 

 given by Messrs. Rothschild and Hartert, but most of the 

 greater and median wing-coverts are edged with rufous, as 

 well as the feathers on the cheeks and throat. A young 

 male specimen in the British Museum from the Arfak 

 Mountains agrees with Count Salvadori's description of that 

 stage of plumage. 



This is a very curious and aberrant species ; even the 

 most adult males, such as that obtained by Mr. W. Good- 

 fellow in the Owen Stanley Range and the one procured on 

 Mt. Goliath by A. S. Meek, appear to represent some
