Birds of Celebes: Laniidae. 
whitish grey; ear-coverts reddish brown; chin and throat white; breast pale fawn- 
buft', paler on the ah domen and flanks; under tail-coverts bright yellow; thighs 
pale brownish, terminal half yellow; under wing-coverts and axillaries whitish, 
tinged witli pale fawn-colour; under surface of quills dusky brown, edged with 
whitish on the inner webs; bill dark umber-brown, feet grey or lead-colom-. Culmen 
15 mm; wing 72; tail 61; tarsus 20 (G-adow 5). 
Distribution. Timor (Wall. 5, ten Kate 6); Samao (Mus. Leyd. 7); Saleyer (Weber 7). 
This species is included among the birds of the Celebes Province on the 
ground that two specimens were obtained by Weber in the island of Saleyer v 
and sent to the Leyden Museum. Mr. Biittikofer remarks that the bill is 
stouter than in the typical P. orpheua, but at the same time thinner than in P. 
teijsmanni which has been found in the same island and which appears to be 
the nearest ally of the species. P. teijsmanm is described as having the whole 
head with forehead, lores and ear-coverts uniform ashy grey, while the head of 
P. Orpheus is said to be olive-grey and, as Gadow adds, the lores, forehead 
and superciliary stripe whitish grey, the ear-coverts reddish brown. It may still 
be desirable to test the case to make sure that the Saleyer specimens are not 
the young of P. teijsmanni.

Descriptions. Wallace a 7; Salvador! 2; Gadow 3. 
Male. Above dusky cinereous, head purer cinereous; below rufescent; throat whitish; 
quills and rectrices dusky, margined with cinereous (Salvador! 2). Bill and feet 
black; iris dark (Wallace hi). 
Female. Above cinereous, tinged with olive-green; beneath pale oclrreous yellow, the feathers 
of the throat and breast with a median dusky stripe; lores light ash; chin nearly 
white; quills dusky, bordered with olivaceous; bill and feet blacldsh; iris dark 
(Wallace a 1). 
Distribution. Sula Islands (Allen a 1, hi, .9); Burn (Wallace a 1, b 1, 3, Eosenberg 5); 
? Ceram (Brit. Mus. 3], 
P. rufescens of Sula and Buru and P. lineolata of the same two localities 
were originally described by Wallace as distinct species, but Salvadori seems 
now to have satisfactorily proved that the differences in colorationare of a 
sexual character. Its nearest affinities seem to be with P. cinerascens Salvad. 
of Ternate, Tidore and Morty, in which similar differences between the males 
and females are pointed out (Orn. Pap. II, 228).
