450 ON THE SPECIES OF BATEACIIOSTOMUS [1877. 



not for the larger dimensions, a more massive bill, and a wider gape, it would be most difficult to 

 distin^uisli this bird from males of B. affinis as above described. I am unable to state any 

 feature of its plumage whereby it can be distinguished, other than its having a broad nuchal 

 collar consisting of several tiers of plumes, fulvous-brown at their insertion, crossed by an obsolete 

 brown line, then a fulvous band, followed by a parallel brown line, then a white band, bounded 

 by a third brown line, tlien another white baud edged on either side with a fulvous terminal 

 frint^e and tipped with a black drop. The upper plumes of the series want some of these details 

 which characterize the lowest tier of feathers. The ground-colour of the rectrices is perhaps 

 more rufous brown than pale grey, tinged with tawny as in B. affinis. Wing 5-25, tail 5-0, 

 tarsus 0-G5, middle toe 0-75, bill from forehead 1-12, width of gape 1-38. Tarsus naked. This 

 and the following are the two males referred to by Mr. Sclater (/. c). 



No. 5, 6 {^) adult, ex Banjermassing (Motley, Mns. Brit.). Wing 5-20, gape 1-40, other 

 dimensions as above ; and the plumage offers no points of difference. Tarsus naked. 



No. 6, 6 {X) adult, ex Labuan (Lowe, Mus. Brit.). In this example there is scarcely a trace 

 of rufous colouring. The colours of the plumage are brown, black, grey, and white. The colour 

 of the rectrices is a pale grey, the dark transverse bands being formed by the greater number and 

 density of the brown zigzag lines and markings. These bands are not all more or less parallel to 

 one another, but narrow almost to a point inwards to the shaft. Wing 5-40, gape 1-35. 

 Tarsus naked. 



No. 7, 6 adult, ex Sumatra (Wallace, Mus. Brit.). Has the general aspect of the Bornean 

 examples and of those of B. affinis 6 . The wing-coverts are broMu with rufous markings. The 

 white nuchal collar-plumes are tipped with large black triangular drops. Pectoral plumes (other 

 than the white) rufous lineated with brown. The caudal bands have alternately a grey ground 

 and a rufous ground strangely contrasting, both traversed (but not unequally) with numerous 

 zigzag brown lines. These bands are parallel. Wing 5-20, gape 1-35. Tarsus naked.

 Bub P. cumulus), that the part, no. i', in which tlie plate appeared must have been published iu the year lii2li, or earlier.
