black, finely verraicnlated with reddisli bvowii, quills deep brown, outer webs witli 

 pale rufons-brown spots, tail dusky with pale reddish brown and blackish cross- 

 bars ; the underside is salmon-buif, each feather with two or three blackish shaft- 

 sj)0t8, here and there vermiculated with blackish. 1 think this must be an adult 

 male, the adult/emales and young being rufons-cinnamon, as described I l.c.c. 



As this species was hitherto unknown in a brown pliase (whether they are all 



females and immature birds, or whether the adult bird is dimorphic, occurring in a 



red and in a brown plumage), this specimen obtained by Doherty is of great interest. 



Aeyotkeles crinifrons difl'ers widely from Ae. insiynis (Arfak, New Guinea), 

 principally in the entire absence of round whitish spots on the back, in the butf, not 

 whitish patches on the underside. Ac. crinifrons is only known from Halmahera 

 and Batjau, Ae. irisiyitis from a single specimen from Arfak, New Guinea (cf. Ibis 

 1896. p. 375. PI. VI.). Ae. pidcher Hartert {Bull. B. 0. Club viii. p. viii. October 

 1898) is the representative of xk. insignis in the mountains of British New Guinea. 

 It is larger, and differs in some details of markings, but should probably only be 

 a subspecies. It would be most interesting to find a brown " phase " of Ae. insiynis 

 and Ae. pulcher, as we now know it to occur in Ac. crinifrons.

 The latter two gentlemen sent a large series each. Among Doherty's specimens 

 many are in the plumage of the sujiposed adult male, marked by Doherty as 

 females, and with the following note : "The sex-colouring seems reversed in this 

 species." It is hardly probable that such a careful naturalist as Doherty made 

 a mistake, as he deliber.itely callrd attention to the phenomenon ; but some of the 

 specimens, wliich are exactly like those marked an J'cmales, being marked as malcx, 

 it is probable that the adult males and females are alike, those with a black thi'oat 

 (formerly 8uj)poscd to he females) being young.
