 may be a trifle broader, the under surface is of the same deep rufous 

 tint ; and the flanks a little more distinctly barred, the rufous 

 spots and bars on the tail are closer together but not continuous. 



Sj)m. No. 3. This bird had apparently only just arrived in adult 

 plumage, but the whole of the colouring is much brighter than in 

 any other specimens I have examined. The whole of the upper 

 surface is of a fine rich slate-blue, head and wings rich blackish 

 brown ; tail blackish brown washed with slaty blue on two central 

 feathers, and outer webs of remainder tipped, and barred in most 

 instances quite across the feather, with rufous the two central 

 feathers barred with slaty black, the interspaces near the base 

 tinged with rufous ; the cheeks, ear-coverts, and region of the eye, 

 brownish black ; forehead buff tinged with rufous ; a few tawny 

 feathers on the sides of the neck ; throat white, lower parts tinged 

 with rufous buff", all the feathers with blackish shaft-lines. All the 

 under surface light rusty rufous deepening into rufous on the 

 breast, sides, flanks, and thighs ; down the breast are broad 

 •streaks of blackish brown, which alter into narrow-shaped mark- 

 ings having a slaty-blue tinge on the side, and irregular broad 

 cross bands of the same tint on the flanks ; on the abdomen and 

 remainder of under surface the shaft-stripes are very narrow, but 

 -slightly swollen near the tips of the feathers on the legs ; on the 

 thighs they are occasionally hastate or arrow-shaped ; the prima- 

 ries and secondaries narrowly marghied with white at the tips ; 

 bill bluish horn-colonr, blackish at the tip ; lower mandible lighter 

 at the base ; cere bluish grey ; feet flesh grey ; claws black.
