:30 ZOOLOGY OF THE S0L0:M0N ISLANDS, 



towards maturity as described in A. versicolor. A young bird as 

 will be hereafter noticed, becoming white below. The specimen 

 mentioned and figured by Mr. J. H. Gurney, Ibis, 1881, p. 2.39 

 is probably a female, but I have seen one specimen said to be a 

 male, with white under surface and much smaller than the 

 others. 



A 3'oung bird (No. 10) is similar to the young of A. versicolor 

 No. 3, but is very much smaller and is older than No. 2, 

 having the crown, nape and a portion of the interscapular region 

 already black, the throat is white and there are large patches of 

 white on the breast, but the bars on the rufous feathers below 

 are hastate or bracket-shaped, and narrower, much the same as 

 those on the young female No. 3. ; this bird is marked a male 

 and if the determination is correct then there are two distinct 

 species, and Nos. 1, 2, and 3, must retain the name of ^4. versicolor. 

 Morton's notes state, that the eggs were well developed in No. 

 1, and Nos. 2, and 3 ; both females were shot together.
