ciniuiinoii niloiis. The \viii_i;-covei'ts and seconduries are black, 

 broadly edged and tipped with cinnamon rufous ; the primaries 

 are only narrowly edged. The great \vhite wing-patch of the 

 adult is only indicated by the last greater wing-coyert and the 

 bases of one or two of the innermost secondaries. (This patch 

 appears, however, to be somewhat different in different indiyiduals). 

 Tiie loAver parts are pale bu(f with dark brown edgings to the 

 feathers of the breast, the belly, flanks and under-tail-coyerts being 

 uniform. As Stejneger^^ has stated, there is " no black at the 

 base " of the throat. Another moult is thus necessary before these 

 birds assume a plumage which approaches that of the adult. 



Young females are similar to young males but paler, the 

 buff markings of the latter being substituted by sandy or dirty 

 whitish. 



According to Nikolske this bird breeds in great numbers in 

 the yalleys of the central parts of the island. Professor Ijijia's 

 expedition collected eggs of this bird at Tretiya Padj on June 

 loth, 28th and oOtli. A complete set contained 5 eggs.

The length of Aving in these specimens agrees with the 

 measurements recorded by Stejneger"^ for typical N. famiyaius 

 from Japan, being 52 mm. in the males and 50 mm. in the
