Hab. Java. 



Bernstein {I. c), who gives an account of the nesting of the Java 

 bird, states that the iris is pure sulphur-yellow. Careful examina- 

 tions of an authentic Javan example in rufous plumage (^mus. 

 «o*^r.), though lacking all the rectrices, has led me to doubt the 

 specific identity of typical B. javensis with Sumatran and Bornean in- 

 dividuals. The bill, on comparison, is less massive, and the gape 

 narrower. The dimension of the wing and tarsus are less. Hors- 

 field's type specimen still exists, but in a deplorable condition, in 

 the India Museum at South Kensington. With the exception of 

 one or two broken rectrices and a few scattered plumes, the whole 

 of the webs have been destroyed by the moth. Yet enough of the 

 type remains to show that the width of the gape, the form of the 

 bill, and the dimensions of the wing and tarsus agree with mv 

 authentic Javan example ; and I feel therefore justified in separating 

 the Sumatran and Bornean species from that inhabiting Java. Still 

 they are but representative forms of one another, and along with B. 

 affinis constitute a small characteristic group. 



$ (?) not in quite perfect plumage (?), ex Java {mus. nostr.). 

 Bright rufous or chestnut. Lengthened auriculars brown for the 

 greater part of their length. Frontal long imperfect plumes brown, 

 almost black. A yellow, chestnut-tinged supercihum. Feathers 

 before the eye pale rufous-yellow at base, with a transverse rufous 

 or else brown line near the tips, which are bright rufous. A series 

 of nuchal plumes pale rufous white, then an irregular transverse 

 rufous brown narrow bar, followed by a broad white band, ter- 



' This is the date on the titlepage of the complete work ; but it is evident, from 

 Temminck's remarks (PL Col. 159, sub P. cornutus), that the part, no. 2, in 

 which the plate appeared must have been published in the 3-ear 1823, or earlier.
