as in the Russell Island bird, and with the interspaces quite 

 as white. 



The distinguishing features of B. gurneyi appear to me to 

 be the white under wing-coverts, the very dark hue of the 

 transverse pectoral and abdominal bands, and the compara- 

 tively great extent of the grey tint on the interscapular 

 region. 



Some remarks of mine on a Baza from the New Britain 

 Group' will be found in the 'Proceedings of the Zoological 

 Society '' for 1879, p. 450. This specimen, which is now in the 

 possession of Captain Wardlaw Ramsay, to whose kindness I 

 have been indebted for an opportunity of re-examining it, 

 agrees with B. gurneyi in the extended nuchal grey colouring 

 and in the white under wing-coverts (which latter peculiarity 

 was noted by Count Salvadori in the ' Ibis ' for 1879, p. 318), 

 but differs from it in the transverse bars on the underparts 

 being broad and of a pale grey instead of narrow and of a 

 dark blackish slate-colour; these bars are decidedly wider 

 and of a paler grey in this specimen, even than in the typical 

 B. reinwardti, from which, as well as from B. gurneyi, I 

 believe the New Britain bird to be subspecifically distinct, 

 though it may be wise to wait for additional specimens before 

 proposing for it a separate subspecific designation.
