464 Mr. J. H. Gurney's Notes on 



M, from Amboyna. Nearly adult, but retains the tail- 

 feathers of the immature plumage unraoulted ; in these the 

 inner webs of the lateral rectrices are marbled, not barred ; 

 it also retains the primaries and tertials unmoulted, and in 

 these the inner webs are transversely barred, but in the 

 secondaries, whieh are newly acquired, they are unbarred ; in 

 other respects the plumage agrees with G, except that the 

 dark shaft-marks are rather more widely spread on the crown, 

 and are also apparent on the back of the head. 



N, from New Guinea. This is an interesting specimen, 

 as it is moulting, and the dress which it is losing and that 

 which it is acquiring are both adult ; some of the new pri- 

 maries are transversely barred on their inner webs, whilst 

 the remaining old primaries are all unbarred ; the rectrices 

 are newly acquired, and show a very slight amount of barring, 

 broken into spots ; in other respects the plumage resembles 

 that of K and L. 



O, from Percy Island. An adult bird, resembling L, ex- 

 cept that it exhibits dark transverse bars on the inner webs 

 of the rectrices, other than the central pair, and also on those 

 of many of the primaries, secondaries, and tertials. 



P, from Port Essington, North Australia. An adult spe- 

 cimen, which resembles L, with the following exceptions, 

 viz. — a few very slight dark shaft-marks apparent on the 

 centre of the crown of the head, and dark transverse bars on 

 the tertials, and, less distinctly, on some of the secondaries. 



Q, from Rockingham Bay, N.E. Australia. An adult, 

 with dark transverse bars on the tertials only ; in other re- 

 spects resembling P, with the exception of having well-marked 

 dark shaft-marks on the nape, and also the strise on the 

 crown of the head being rather more widely diffused. 



R, from the east coast of Australia. Adult, resembling O 

 in all respects. 



The following are the principal dimensions of eight speci- 

 mens of Haliastur intermedins and H. girrenera which are 

 preserved in the Norwich Museum, and of which the sex has 

 been recorded by the collector : —
