Birds of Celebes: Campophagidae. 417 



the former with shite-grey edges above and much paler below, mcliniug to whitish 

 on the inner webs; bill black; legs and feet in skin blackish (Banggai Id., V. — YITT, 

 95; Nat. C(3ll. — C H710). 



Adult [female]. Slate-grey as in the male, but the head, neck, and tkroat uniform with the 

 rest of the plumage, blackish only on the lores and ear-coverts (Banggai — C 14711). 

 The type of the species is a female from Sula and is described by Sharpe as 

 follows: Like G. pollem of the Kei Islands, but smaller, and paler ashy; the feathers 

 at the base of the nostril, loral plumes, and feathers in front of the eye dull blackish, 

 not glossy black as in O. pollem. Wing 161 mm; tail 145; tarsus 24; culmen 27. 

 0. pollens is described as deep lead-grey; under wing-coverts concolourous, the 

 greater series grey, finely tipped with black; quills blackish, below greyish; tail- 

 feathers black, the outermost paler at the tip; iris, bill and feet black (ex Salvad.). 



Measurements. "Wing 154, 157 mm; tail 130, 132; tarsus 22.5, 24; bill fi-om nostril 18, 20. 



Distribution. Sula Islands (Allen a 1, c 2); Banggai Island (Dresden and Tring Mus.). 



A single specimen, apparently a female, of this species was obtained by 

 Allen in Sula Besi or Sula Mangoli, and it was described in 1878 by Dr. 

 Sharpe as G. sckistaceus. In 1895 the native hunters working for the Dresden 

 Muse.um collected four'examples in Banggai, but, as we pointed out in describ- 

 ing the collection (1), they may prove to be racially different from G. schista- 

 cens., since the tyjie of that species is said by Sharpe to have the "under 

 wing-coverts blackish, much darker than the breast", whereas in the Banggai 

 birds they are concolourous with the breast. 



G. sckistaceus is one of a number of closely related geographical species. 

 G. lavatus (S. Miill.) of Java is below paler grey than above, while G. sckistaceus 

 is equally dark above and below. It has affinities also with the following forms: 

 G. normani Sharpe from Kini Balu (Ibis 1887, 438), the male of which is 

 without the black head, G. melanocephalus Salvad. of Sumatra (Ann. Mus. Civ. 

 Gen. 1879, XIV, 206), which differs in respect of the tail, G. mindorensis (Steere), 

 without a black head in the male, but Avith the black of the lores extending 

 about the eye (List B. Philipp. 1890, 14), and G. guillemardi Salvad. of Sooloo, 

 a race of G. pollens. Prof. W. Blasius (J. f O. 1890, 142). misled by the simi- 

 larity of the orthography, has recorded G . sckistaceus from Sooloo, but Mr. Wallace 

 was never in this group, which is inhabited by G. guillemardi. 



Graucalus atriceps (S. Miill.). Celebes was indicated as the habitat of this 

 species by Salomon Miiller. This locality, as Salvadori remarks, is cer- 

 tainly erroneous (Orn. Pap II, 128), and the true habitat seems to be Ceram, 

 where the bird was rediscovered by Wallace.
