Birds of Celebes: Treronidae. 
slate, greyer at tip. “Iris light red; bill light gamboge-yellow; feet cherry-red” ((J', 
Malibagii in Gorontalo Distr., 22. XU. 93: P. & F. Sara sin). 
Female. Does not seem to differ in coloration. 
Measurements. Wing 167— 183 mm (6 specimens); tail 145 ca.; tarsus 25 ca.; bill from feathers 
of forehead 17 — 18. 
Distribution. Celebes: — Minahassa (Quoy & Gaimard a /, Porsten 2, Wallace 7, etc.); 
Gorontalo Distr. (Rosenb. 2, Riedel, P.&F. Sarasin); Gulf of Tomini (Meyer c 5); 
Tonkean, E. Cel. (Nat. Coll, in Dresd. Mus.); West Celebes, Tawaya (Doherty h 3). 
In Inly, 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 fin the Paris Museum 
(3). This pigeon is not yet known from South Celebes, and it [seems to he one 
of the rarer members of the Columhae in the North. After P. suhgularis, its 
nearest known affinities are with Ptilopus kclancheri (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, 
Irerolaema yC. 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 limoiiaut 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. 
257. PTILOPUS SUBGULARIS M.&Wg. 
Banggai Maroon-chinned Fruit-pigeon. 
Ptilopus subgularis ( 1 ) M. &Wg., Abb. Mas. Dresd. 1896, Nr. 2, pp. 4, 6, 19. 
“Bukun”, Peling and Banggai, Nat. Coll. 
Diagnosis. Like P. gidaris, 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., Peling, V.— VDI. 1895: Nat. Coll. — 0 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. Peling and Banggai (Nat. Coll, in Dresd. and Tring Museums). 
ihis 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
