ART. 16. BIEDS FROM NORTH CELEBES RILEY. 17 



from the shoulders by an irregular bar of iridescent purple, divid- 

 ing the yellow breast patch, which is poorly developed; and it is 

 very dark above with much iridescent purple on the mantle. Like 

 some other specimens the purple nuchal band is interrupted behind. 



Salvadori's ^^ description of the tail, which he uses as one of the 

 ■characters to separate two Celebes forms in his key, is probably taken 

 from a not fully adult bird in the case of his tristigmata^ as none of 

 the adults before me are as he describes this feature. All the birds be- 

 fore me, except the immature, have the five outer tail feathers slate 

 gray with a subterminal black band. The immature mentioned 

 above has only the two outer tail feathers slate gray with a sub- 

 terminal black band, the next feather changing from olive to gray 

 ■with a subterminal black band and gray tip, the next two olive with 

 gray tips, and the remainder as in the adult. From the above, I 

 judge, the skin of the northern form that he considered to be adult 

 is not really so, and as mentioned above the nuchal band is either 

 entire or interrupted in the same locality. As he had before him 

 only one specimen of the northern bird and one from the south, it 

 appears as if his Phlogoenas himaculata is not well founded. 



For Phlegaenas tristiginata Bonaparte, which differs structurally 

 from Gallicohmiba Heck {Phlogoenas of authors), in having the 

 tarsus about a fifth longer than the middle toe with claw, instead 

 of nearly equal, a different color pattern, and other characters, I 

 have erected the genus Dioyezus?^ 



This pigeon is very shy and extremely alert and though I have seen it several 

 times, I have never been able to obtain a shot. It inhabits heavy forest and 

 flies up similar to a partridge, but before a gun could be raised it has dis- 

 appeared amongst tlie dense foliage. — H. C. R. 



The food of two birds, which were examined by Mr. Raven, con- 

 sisted of hard red fruits about the size of a pea, another hard fruit 

 somewhat larger, remains of a cicada, green grasshoppers, crickets, 

 beetles, and small grubs.

One male, Kwandang, September 15, 1914; one female, Rano

These two specimens are in widely different plumages. The male 

 is in worn plumage and as Meyer and Wiglesworth's description ^* is
