ACCIPITRES. 13 



death, may be briefly mentioned : — Baza bismarcki, Sharpe, 

 from New Britain, Gazelle Island, April 19, 1891 ; Baza 

 sumatrensis (Lafr.) from Meple in Burma, January 1891 ; 

 Leucopternis semiplumbea, Lawr., from Costa Rica : see 

 particulars in the ' Ibis ' for 1893, p. 340, of these three 

 novelties. My father's remarks on eleven species of the 

 genus Baza form one of his papers in the 'Ibis,' 1880, 

 pp. 462-471 ; and those on the handsome South-American 

 genus Leucopternis are to be found in the 'Ibis' for 1876, 

 where he especially alludes to the great rarity of Baza 

 sumatrensis and Leucopternis semiplumbea, which makes 

 their acquisition the more gratifying. 



In June 1893, Mr. A. Boucard received from Majunga, in 

 the north of Madagascar, and forwarded to Norwich, a S^a- 

 Eagle, Halia'etus vociferoides, Des Murs, probably a bird in 

 its second year, with a white tail, but not adult. It cor- 

 responds well with the figure in Des Murs' Iconogr. Orn. 

 plate vii., which has a white chin, a rufous chest, and a dark 

 brown back. Compared with an example of H. vocifer, 

 Daudin, collected by Du Chaillu on the Ogobai River, 

 W. Africa, apparently of the same age, also in the Museum, 

 it is seen to differ in its rufous breast, whiter chin and 

 cheeks, and darker nape, and the crown is more rufous. 

 The chin, however, is not white, as in Des Murs' plate, but 

 very pale brown. 



The wing in this H. vociferoides is 2T50 inches, the tarsus 

 3*25, middle toe 3 55, tail 1050, culmen 2 - 40. It has a 

 somewhat larger beak than any of the H. vocifer skins in the 

 Museum, between which and H. leucoryphus (Pall.) it will 

 now take a place. In 1878 my father was not aware of a 

 single specimen of H. vociferoides in England, and I have 

 often heard him express a wish to possess one. Mr. Sclater 

 has examined another in the Senckenbergian Museum at 

 Frankfort (' Ibis,' 1894, p. 108), and there are three at 

 Paris and two at Ley den, but they are very rare. ' Ibis/

To Mr. C. B. Rickett the Museum is indebted for Micro- 

 hierax melanoleucus (Blyth), from Foochow, in China, and 

 M. chinensis, David (M. sinensis, Sharpe) ; but the latter is
