 136. CYORNIS BANYUMAS OMISSA (Hartert). 



A small series of adults and young of both sexes from: Koelawi, 

 February 23, 1917; Kano Lindoe, March 6-23, 1917; Toewo Moun- 

 tain, Besoa, October 31-November 4, 1917. 



I have been able to compare the above series with an adult male 

 and female from Java and the birds from the two islands are quite 

 distinct. In the male of the Javan form {Gyornis hanyumas haivyu- 

 nias) the line on the forehead and over the lores is very light blue, 

 while in the Celebes bird it is much deeper. The black on the chin 

 is narrower, the lores deeper, and the ear coverts darker in the 

 Javan form. The belly is whitish in the Javan male while in none 

 of the Celebes specimens is it so; the lower parts are also deeper 

 in the latter. The female of Cyornis hanyumas omissa in the color 

 of the back, wings, and tail, is only a lighter duller blue, than the 

 male, while in the female of the Javan race the back is deep olive, 

 the wings edged with buffy brown, the tail and upper tail-coverts 

 cinnamon-brown. There are other differences, but the above is suffi- 

 cient to show that the two races are very distinct and it is doubtful 

 if they should only be recognized as forms instead of distinct species. 

 However, out of deference to Hartert's^^ opinion, such an arrange- 

 ment will show their relationship better and is retained. 



An immature in the spotted plumage of about the same size as the 

 adult was taken November 4, and two additional immatures that have 

 begun to assume the adult plumage were taken March 6 and 21. 

 Judging from the above more than one brood must be raised in a 

 season, and the breeding period extends over a considerable part of 

 the year.
