OX THE BIKDS OF CELEBES, [1872. 



of the upper surface not quite so bright a chestnut. In it also the tail is not forked, and the 

 outer pair of rectrices are shorter than the middle. 



The third example is of a young female passing from the chestnut plumage of no. 2 into 

 that of the adult. The nuchal feathers are ashy ; and a few similar plumes are interspersed on 

 the throat and upper part of the breast. The breast-feathers and a few on the flanks are pure 

 A-inous red. A few of the upper tail-coverts are dark ashy ; and one of the long wing-coverts 

 has come in ash-coloured, and with two pure white spots on the inner web. The chestnut 

 colouring of the remainder of the plumage is very dingy and faded. The tail is not forked. 



Dimensions. 



The toes are measured without the nails. The nails of the inner toe and hallux are very 

 large, strong, and equal. Those of the middle and outer toes are slender and short.

This species also inhabits China, extending at least as far north as Pekin (Swinhoe, P. Z. S. 

 1871, p. 342).

Four examples from North Celebes have reached me — two (male and female) fully adult, 

 and two (male and female) in the immature plumage already described {I. s. c). The adult pair 

 do not differ ; and the example of the immature female only differs from that of the male by 

 having the two pairs of middle rectrices more frequently banded and in a different manner. In 

 the adult birds of both sexes the middle rectrices have a broad, terminal, dark brown band ; then, 

 above, a broader band of pale greyish brown, and then three narrow dark brown bands separated 

 Tr.Z.S. viii. by broad pale bands. This is also the character of the banding on the middle rectrices of the 

 ^*' ^^^" immature male. But in the immature female there is no terminal dark-brown band, and the 

 middle rectrices are almost evenly divided by seven pale and seven dark-brown bands. Yet in all 

 other respects the immature pair are identical in plumage.

An examination of several examples of the Celebean IIoney-Buzzard has convinced me that 

 it is distinct from the Indian and Javan species. In this view I am only concurring with both 

 Messrs. (iurney and "Wallace, and therefore propose the above title for it. The remarkable 

 resemblance of this species to Limnaetus lanceolatus, in adult plumage, has been commented on 

 by Mr. "Wallace and Professsor Schlegel.
