 Sharjpe, Gat. Ace. I, p. 315. 

 H. leucosternus, Gould, Bds. Aust., fol. vol. J, jpl. IV. 

 This fish-hawk was met with only on two or three occasions ; 

 the collection contains five specimens, in no way dififerent 

 from those of the New South Wales coast. 



3. — Haliastur sphenurus, Vieill. 

 Sharpe, Cat. Ace. I, p. 316; Gould, Handhh. Bds. Aust. vol. I, p. 20. 



Common at Port Moresby, and all along the coast.

One very fine adult male from Broadbent's collection, shot 

 inland on the Laloki River; it agrees with Mr. Sharpe's descrip- 

 tion (Cat. of Bds. I, p. 359) of B. reimuardtii, but is most cer- 

 tainly different from the 'New Ireland species, which Dr. Sclater 

 places under the same name. P.Z.S., 1877, p. 109. 



The Port Moresby bird has five distinct black bars on the 

 basal portion of the tail, and the apical third of the tail black on 

 the central two feathers, diminishing in extent on the re- 

 mainder, until on the outermost feathers it forms a s^t&-terminal 

 band, the black basal bands are margined on both sides with 

 white on the inner webs of the feathers of the upper surface, 

 which are white at the extreme base. All the bars extend 

 right across the feathers on the upper surface, but none do so 

 on the under surface, except in the centre two feathers ; the 

 breast, flanks, upper part of the thighs, and centre of ahdomen 

 are banded ; the primaries and most of the secondaries are 

 banded right across on all, except at the base of the secondaries ; 

 in our New Ireland birds the primaries are not crossed 

 altogether, and the bands are confined more to the tips of the 

 feathers, the bands on the base of the tail are different in form, 

 and the apical half of the tail is black.
