so doing he lays considerable stress upon the value of 

 coloration as a factor in generic determination. 



Among the other genera Haliastur Indus is stated to have 

 four recognisable subspecies ; but these are connected by 

 various intermediates, and the species is consequently left 

 undivided in the absence of more precise information. 

 It is sliown that '^ girreaera" is a synonym of " pondi- 

 cerianus''^ and cannot be used for the Australian bird 

 more properly called leucosternus. Haliastur lies between 

 the Sea-Eagles and the Kites, while it is noticeable as 

 having the mewing cry of the latter. A smaller and 

 lighter form of Haliastur sphenurus is made a new sub- 

 species '' sarrasini." 



One new genus is proposed in this part, Neobaza with 

 type N. madagascariensis ; Baza is restricted to B. lophotes; 

 Aviceda and Lophastur are accepted as valid genera. 



Several pages are required to elucidate the confusion 

 concerning the Latin names of the two Australian Elani, 

 with the result that notatus of Gould takes the place of 

 axillaris, and scriptus stands as aforetime. 



With respect to the rejection of Gmelin's korschun for 

 Milvus migrans, Mr. Mathews recalls the fact that Milvus 

 was once used for both Harriers and Kites, to which the 

 reviewer may add that in Norfolk the male Harrier is a 

 " Kite/' and in Wales he has heard the Buzzard called by 

 the same name. The Australian or Allied Kite is but a 

 subspecies of M. migrans. 



For several other subspecies formerly proposed, but 

 cancelled after further consideration, readers must consult 

 the pages of the work.

This paper is chiefly concerned with the identification and
