Birds of Celebes: Treronidae. f)! ] 



in colour of the group, to which Count Salvadori gave the subgeneric name 

 Sjnlotreroti. 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. melanospilus — chtysorrhous , 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. meUtnocephalu^, but larger}; vent and shorter under taU-coverts deep 

 orange; occipital black patch broader (Great Sangi, 20. VU. 93: Nat. Coll. — C 12660). 

 "Iris yellow, feet cherry-red, bill yellow-green" (Platen 2). 



Adult female. Parrot^green, abdomen yellower, head and throat greyer; longest under tail- 

 coverts lake-red, tipped with dark yellow (Great Sangi, 30. Vii. 93: Nat. Coll. — 

 C 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 immatui-e (Tagulandang, Aug. 1894: Nat. Coll. — 

 C 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 which 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; culmen 14.5 — 17.5 mm. 



Specimens from Biarro, Ruang, Tagulandang and Siao are not intermediate 

 between P. melanospilus and P. xantlim-rhous, but agree with the latter, as the follow- 

 ing mea.surements of adult males only show:
