434 THE MARaUIS OFTWEEDDALE ON BATRACHOSTOMUS. [May 15, 



with brown. A few feathers on the tarsi. Wing 5-30, width of 

 gape 1-30. Other dimensions as in Lampong example. 



No 3 2 C) young, an immature example of B. cornutus m rutous 

 dress, exBaniarmassing.in the British Museum, is almost entirely of 

 a pale isabelline-rufous, freckled with dark irregular transverse 

 zigzag lines. Here and there, especially on the head, the uniform 

 rufous feathers of the older stage have come in, and also a ew ot 

 the white scapular, nuchal, and pectoral plumes. Ihe mandibles are 

 weak, evidently not full-grown ; but the width of the gape is equa 

 to that of B. affinis when adult, and the wing is longer than in that 

 species, otherwise it would be difficult to determine to which species 

 it belongs. Wings 5-10, tail 460, width of gape MO. 



No.4, 6 (?) adult (?),exBanjarmassiug (Motley, mns. nostr^. (i"!. 

 XL VI ) Were it not for the larger dimensions, a more massive bill, and 

 a wider gape, it would be most difficult to distinguish this bird from 

 males of B. affinis as above described. I am unable to state any 

 feature of its plumage whereby it can be distingmshed, 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 hue, then anotlier white band edged 

 on either side with a fulvous terminal fringe and tipped with a black 

 drop The upper plumes of the series want some ot 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 iu^. affinis. Wing .V25, tail S'O, tarsus Q-bo, middle 

 toe 0-75, bill from forehead 1-12, width ot gape 1-38. Tarsus 

 naked. This and the following are the two males referred to by

No. 5, 6 0) adult, ex Banjarmassing (Motley, J/«5.^n^). Wiug

 no pomts of difference. Tarsus naked. . , , • i 



No 6 d (n adult, ex Labuan (Lowe, Mus. Brit). In this example 

 thereis scarcely a trace of rufous colouring. The colours of the plumage 

 are brown, black, grey, and white. The colour ot 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. Ihese 

 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 l-3o. 



Tarsus naked. ,.„.„, i 



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

 aspect of the Bornean examples and of those of B. affinis S ■ iue 

 wing- coverts are brown 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. Ihe 

 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.
