(J 10 Birds of Celebes: Treronidae. 



one by Prof. Weber. One of Platen's birds, mentioned by Prof W. Blasius 

 (2), is now before iis; it seems to have the occipital black patch somewhat 

 smaller, and the hike-red under tail-coverts deeper in tint. Of Togian birds 

 Meyer has remarked (d 2): "My specimens from the Togian Islands (August) 

 appear to ditfer a little, the head being rather violet than black". The Sangi 

 race, P. xanthorrhous, is larger, has a 'larger bill and is of a shade darker green; 

 it is interesting to tind that s])ecimens from Banka belong to Celebes, but those 

 of Biarro, Tagulandang and Gunong Aj)i to Sangi. 



Meyer syllabities the cry of this Pigeon as 'hiiu', hollow, and difficult to 

 imitate. It generally flies in pairs and feeds on fruits.

Descriptions. Wallace a 1\ Salvadori c 1, 4, 5. 



Adult male. Like P. nielatiocephalus, but the black occipital patch small, almost confined to 

 the nape; giUar stiipe orange; vent and shorter under tail-coverts dark orange (cad- 

 mium-orange); tail below blackish, broadly tipped with grey; sides of lower liind neck 

 yellowish green; under surface of body considerably darker green than the upper (o^, 

 Sula Besi, fi-om Boucard — C 10486). 



Measurements. "Wing 116 — 120 mm; tail 85 c; tarsus 20 c.; bill fi-om feathers of forehead 

 14.5 — 15 (Sula, 3 adult male examples); wing 109—114 mm (5 adult males, Peliug 

 and Banggai). 



Distribution. Sula Islands: Sula Besi (Bernstein b 2, Hoedt b 2), "Sula Islands" (Allen 

 a 1, or, Peling and Banggai (Nat. Coll. in Dresd. and Tring Mus.); Ceram (Moens 

 b 1, b2, Wail, b 1. b 2). 



Two individuals from Ceram are recorded by Schlegel, who states that 

 they are absolutely identical with Sula birds. Most likely the species has 

 strayed to Ceram in recent times. The differences of the Sula birds from those 

 of Celebes and Java were first pointed out by "Wallace, and afterwards con- 

 firmed by Schlegel and Salvadori. The last writer speaks of the gular stripe 

 as like that of P. melanospilus, but we find it narrower and orange in colour, 

 as against deep lemon-yellow. The Sula race is one of the best-marked of the 

 group; on the whole it and the Javan form seem to mark the extreme variations
