552 MR. F. L. SCLATER ON THE BIRDS [June 19, 



the " Pacific Ocean," 1875. For some details of the ' Challenger's ' 

 visit, and remarks on the nature of the country, which appears to be 

 densely wooded, Lieut. Campbell's 'Log-letters' (p. 259 et seq.) 

 may be referred to. 



The specimens of birds obtained during the sojourn of the ' Chal- 

 lenger ' at Nares Harbour are 5G in number, and embrace examples 

 of 27 species. Of these seven appear to be new to science.

2. MoNARCHA inornatus, Garuot. 



Muscicapa inornata, Garnot, Zool. Voy. Coq. i. p. 590, Atlas, 

 t. 16. fig. 1. 



Monarcha inornata, G. R. Gray, P. Z. S. 1858, p. 177. 



Three skins (493, <S ; 494, J ; and 495, $ ) of this species are in 

 the collection. The sexes are alike. 



"Eyes hazel : bill and feet indigo-blue." — J. M. 



I have compared them with skins of this species collected by 

 Wallace, in the British Museum. M.fulviventris, Hartlaub, P. Z. S. 

 1867, p. 830,of the Echiquier Islands, is nearly allied, if not identical.

 luni et cervicis lateribus albis ; subtus albus, gula et pectore toto
