islands of the archipelago have produced different forms of tliis group of Pachycepkala. 

 Therefore more evidence should come forth to make sure that P. firineonota of Gray 

 is the same as the Snla bird. Then Wallace described on j). :U1 of P. Z. S. 1802 

 P. lineolatu and P. ni/'esccns, both from " .Sula aiul Bourn Islands " {sic). It is 

 Salvadori's opinion that J', lineolafa is the young bird, whih; Gadow seems to consider 

 it to be the /e/«a/t'. I believe it is the immature dress. If P. lineolata and 

 P. rufescens refer to the same species, then the name P. lineolafa must stand, 

 coming first on the page. It is, in my opinion, doubtful if the Burn form is exactly 

 the same as the one from Sula, but more material must come to hand before we can 

 decide about this. If the Burn bird diflers, it will require a new name. Two 

 specimens named P. rufescens, one from Sula and one from l?uru (the latter with 

 a " ? "), are marked " type " in the British Museum, but these words were not written 

 by the author himself. 



24. Pachycephala clio A\'all. 

 A large series from Sula Besi and Sula Mangoli. i ad. " Iris deep brown ; 

 feet bluish black ; bill black." ? ad. " Iris dull brown : feet j)ale leaden ; bill 

 black." Dr. Gadow's conclusion {Cat. B. Brit. Mus. VIII. p. 187) that P. tnerula 

 (Less.) from the Moluccas, P. melanura Gould from Australia, P. clio Wall, from 

 Snla (" and Burn "), and P. obiensis are all the same is not correct. There are three, 

 if not four, distinct species or subspecies. The name clio clearly belongs to the 

 Snla form. 



25. Graucalus melanops (Lath.). 



One 7nalc from Sula Besi. Messrs. Meyer & Wiglesworth have recorded it 

 from Peling. 



26. Graucalus schistaceus (Sharpe). 



Sharpe {Cnt. B. Brit. }fu.'i. IV. p. 11) described n fon/ili'. The mrile has 

 the entire iiead and neck glossy black. The specimens from Peling and Banggai 

 are exactly like those from Sula Mangoli, and the nnder wing-coverts are always of 

 the colour of the breast and abdomen. " Iris very dark brown ; feet and bill black." 

 It was not found on Sula Besi. 



27. Lalage leucopygialis Walden. 

 ?, October 1897, Sula Besi. 



28. Edoliosoma obiense Salvad. 



There is a series marked as ma /ex from Sula Mangoli and Sula Besi. With 

 three male skins before me from Obi Major I cannot detect any tangible differences. 

 The bill, nevertheless, is generally — but not always—a little shorter in the Sula 

 specimens. 



Then there are three specimens marked as /;•«;'(/-■.>■, which <litfer from the mnlcs 

 in having the under parts paler grey and no black on the head. One of them shows 

 remains of bars on the abdomen and rufous edges on some c.f the wing-feathers. I 

 am not sure that these three so-called females are wrongly " se.xed," for one male 

 in moult from the first rnfous plumage shows already traces of the black on the lores 

 and sides of the head. If rlie sexes are riijfht, then we are entirelv in error about
