above the eyes brownish buft'. Hind-neck and uppermost part of back like the 

 head ; remainder of upper parts bright cinnamon-rufous. Remiges brownish black, 

 the inner edges of all whitish bnff; outer edges of secondaries bright rnfons.

 cinnamon. Wing 68, tail 80, metatarsus 18, culmen 13 mm. $. Smaller, wing 

 about 62 mm. Obtained by Dumas on Mount ]Mada, at about 3000 feet. 



It will be an interesting, though difficult work to study all the red-backed 

 Rhipidwae of this group, and to work out their relationship. 



36. Edoliosoma marginatum Wall. 



Evidently common at Kaycli. The /'emu I r differ.s from the male in being a just 

 perceptible shade lighter below and in having much lighter, almost white under 

 tail-coverts, besides being smaller. Wing of ??iale-'< about 11.5, oi females about 

 110 mm. long. Young birds are lighter below, some of the feathers of foreneck, 

 chest, and sides of body with black shaft-lines and spots along the shaft, and 

 wing-coverts deep buff. 



37. Oriolus bouruensis (Qnoy. & Gaim.). 



Kayeli, Bara, Mount Mada. The young birds have rust}- rufous edges to the 

 quills and wing-coverts. 



The wonderful case of mimicry between this bird and the Philemon is related 

 in Proc. Zool. Soc. 1863, p. 26, and in Wallace's Mala>/ Arcldpelaf/o: 



38. Dicrurus atrocaeruleus amboinensis Gray. 



Plentiful near Kayeli and Bara, and not rare on Mount Mada. " Iris always 

 deep brown '" (W. Doherty). 



According to Salvadori two he saw from Burn had the wings longer than others 

 from Ceram and Amboina. The wings of six Burn examples measure 14" to 

 149 mm., that of one from the north-east coast Ui6 mm. 



3'.t. Pachycephala examinata Hart. 



Differs from F. lineolata from the Sula Islands in having the abdomen (which 

 is white or with a faint ochreous tinge in P. lineolata) ochraceous bnif, the under 

 tail-coverts buff instead of white. The wing longer, measuring 81 to 82 mm. 

 Back more brownish, the grey cap thus becoming more conspicuous. The male has 

 the throat white, the chest washed with grey. The female has the imderside 

 uniform ochraceous buff, the wing only about 78 mm. long. Cf Nov. Zool. V. (not 

 IV. as quoted Ball. Ji. 0. Club, VIII. p. 14) p. 131, IMl. B. O. Club, YIII. p. 14 

 (Nov. 1808). 



The name of I', griaeonota is best not adopted at all, but if it should 

 be adopted it would be more sensibly ajiplicable to the Sula form than to that 

 from Burn.
