606 Birds of Celebes: Treronidae. 



slate, greyer at tip. "Ms light red; bill Uglit gamboge-yellow; feet cherry-red" {(f, 



Malibagu in Gorontalo Distr., 22. XII. 93: P. & F. Sarasinj. 

 Female. Does not seem to differ in coloration. 

 Measurements. "Wing 167 — 183 nmi (6 specimens); tail 145 ca.; tarsus 25 ca.; bill from feathers 



of forehead 17—18. 

 Distribution. Celebes: — IVIinahassa (Quoy & Gaimard a I, Forsten 2, "Wallace d 1, etc.); 



Gorontalo Distr. (Eosenb. 2, Riedel, P. &F. Sarasin); Gulf of Tomini (Meyer c 5); 



Tonkean, E. Cel. (Nat. Coll. in Dresd. Mus.); West Celebes, Tawaya (Doherty b 3). 



In July, 1828, the "Astrolabe" anchored at Manado, and the present species 

 and others were then obtained and described by Quoy & Gaimard, the 

 naturalists accompanying the expedition. The type is still in the Paris Museum 

 (3). This pigeon is not yet known from South Celebes, and it seems to be one 

 of the rarer members of the Columbae in the North. After P. subgularis, its 

 nearest known affinities are with Ptilopus leclancheri (Bp.) of the Philippines, 

 which is smaller, has a broad maroon band across the lower breast, and the 

 hind neck grey like the head. Bonaparte made a separate genus for the two, 

 Trerolaema (C. R. 1855,XLI,247). The attenuation of the first primary is as strongly 

 pronounced in P. gularis as in P. fischeri, but the narrowed part varies much in 

 length, viz. 18 mm to 27 mm. In his admirable Catalogue of the Pigeons Count 

 Salvadori unites the present species with P.fischeri, mendionalis and others in 

 the subgenus Leucotreron, a group found from the Malay Peninsula as far as 

 the Timorlaut group, Celebes, and the Philippines, but not known in the 

 Moluccas or Papuasia proper. 



Among the birds of Celebes this species most closely resembles Carpophaga 

 radiata, which may easily be recognised by its black bill, the grey band across 

 the middle of its tail and its white chin and throat.

"Bukun", Pehng and Banggai, Nat. Coll. 



Diagnosis. Like P. gularis, but the crissum and under tail-coverts dark chestnut-brown (in- 

 stead of pale hazel), and the buff patch on the breast very weakly developed or almost 

 obliterated (ad., Pehng, "V^.— VIH. 1895: Nat. Coll. — C 14605, and others). 



Younger. The occiput and hind neck grey-green (Banggai — C 14737). 



Measurements. "Wing 159 — 171 mm; tail c. 130; tarsus c. 25; exposed culmen c. 20. 



Distribution. Pehng and Banggai (Nat. Coll. in Dresd. and Tring Museums). 



This Pigeon is a local race of P. gularis of Celebes. It is interesting to 

 know that P. gularis occurs in East Celebes which is separated from Peling by 

 a strait only about 20 kilometres, or a dozen English miles, wide. The charac- 

 ters given seem to be what are termed "constant". Up to the present no Pigeon
