656 Birds of Celebes: Peristeridae. 



behind the ear-coverts, and the race has been named bimaculata by Count 

 Salvador!, who points out other differences. The two are very distinct from 

 any other members of the genus. Their chief affinities seem to be with the 

 Dagger-wound Pigeons (Dolchstichtauben in German) of the Philippines and 

 Papuasia, especially P. rtifigula (J. & P.) of the latter subregion. These may be 

 recognised by the patch of bristly feathers of a red colour on the upper breast, 

 by the grey bars formed by the tips of their upper wing-coverts, and by other points. 

 The genus Phlogoenas is found only in part of the East India Islands and 

 Polynesia, the western confines of its range being Celebes and the PhiUppines ; 

 then comes a break, for it is not known in the Moluccas, but reoccui's again 

 in Papuasia as far as the Solomon Islands and, apparently, Tanna in the New 

 Hebrides, passing eastward across the Pacific to the Paumotu Islands (Bow) and 

 to Uap and Ruk in the Carolines. A species, which Count Salvador! refers 

 to this genus with a query, is further found in Wetter and Timor. Count 

 Salvador! enumerates 20 species, not counting four of doubtful validity; to 

 these he appends eight others as unidentified. The genus is a difficult one for 

 the student, some of the species not having been met with since the time of 

 Cook and no specimens being now extant in collections. As a rule, indeed, 

 these Pigeons seem to be rare birds where they do occur, judging from the 

 fact that 8 of Salvadori's 20 good species are represented in the British 

 Museum by only 1 specimen each, 2 by 2 specimens each, and 4 by none. 



^* 283. PHLOGOENAS BIMACULATA Salvad. 

 South Celebes Ground-dove. 



a. Phlegoenas tristigmata (1) Wall., Ibis 1865, 393 pt. (Macassar); (2) id., J. f. O. 1866, 



284 pt.; (Ill) Gould (nee Bp.), B. Asia VI, pi. 59 (1873). 



b. Phlegaenas tristigmata (1) Wall, Malay Archip. 1869, I, 369, 413, pt. (Maros Waterfall). 

 Phlogoenas bimaculata (1) Salvad., Bull. B. 0. C. 1892, IH, p. X; (2) id., Ibis 1893, 120; 



(3) id., Cat. B. XXI, 1893, 591; (4) Hart., Nov. Zool. 1897, 160. 

 Figure and descriptions. Gould a III; Salvadori 1, 2, 3. 

 Adult. Similar to P. tristigmata, but somewhat duller, less yellow on the breast, and less 



coppery amethyst on the hind neck and mantle, two purple-violet spots on the sides 



of the upper nape, so that the nape along the middle is entirely bronze-green. Size 



scarcely smaller than that of P. tristigmata (Salvad. 3). 

 Distribution. South Celebes: — Near Maros Waterfall (Wallace b 1); near Macassar 



(Doherty 4). 



This species, the southern representative of P. tristigmata, will possibly prove 

 to intergrade with it somewhere in the middle of Celebes. The southern race 

 seems to be known only by two specimens — the type in the British Museum, 

 figured by Gould (a III), which Mr, Wallace killed near the Maros Falls, 

 and an immature example obtained by Mr. Doherty in July, 1896, having the 

 purple spots on the sides of the nape scarcely indicated and some brown and 

 rusty feathers on the breast (Hartert 4).
