Birds of Celebes: Treronidae. 
6tl 
in colour of the group, to which Count Salvadori gave the subgeneric name 
Spilotreron. We have included the birds of Peling and Banggai with the 
Sula “species”, but it would be preferable in many ways to represent them as 
P. inelunospilus — chrysorrhous , as they occupy a somewhat intermediate position 
between the Sula and the Celebes birds. They run smaller in size than in 
Sula; the orange-yellow of the chin and throat is generally yellower, and often 
just as in Celebes birds, but the black occipital patch is about as small as in 
Sula birds.

Adult male. Like P. mekmocephoLm, but largerj; vent and shorter under tail-coverts deep 
orange; occipital black patch bi’oader (Great Sangi, 20. VII. 93: Nat. Ooll. — 0 12660). 
“Iris yellow, feet cherry-red, biU yellow-green” (Platen 2). 
Adult female. Parrot-green, abdomen yellower, head and throat greyer; longest under tail- 
coverts lalce-red, tipped with dark yellow (Great Sangi, 30. VII. 93: Nat. Ooll. — 
0 12659). “Iris yellow-green; feet cherry-red, bill black” (Platen 2). 
Young. A specimen, similar to that described as an adult female, has the under tail-coverts 
entirely green, and is probably immatiue (Tagulandang , Aug. 1894: Nat. Ooll. 
0 13493). Prof. W.Blasius describes the female plumage as uniform green, but out of 
six examples from Gt. Sangi, Siao, Tagulandang and Ruang the above is the only 
one wliich wants red on the longest under tail-coverts. 
Measurements (20 adult males from Gt. Sangi after Prof. W. Blasius 2). Wing 130 — 140; 
tail 84 — 103; ciUmen 14.5 — 17.5 mm. 
Specimens from Biarro, Ruang, Tagulandang and Siao are not intermediate 
between F. mdanospiMis and P. xanthwrhous, but agree with the latter, as the follow- 
ing measurements of adult males only show:
