will be found two exceptional genera, forming a link 
between the Buzzards and the true Hawks, and known 
as the Buzzard Hawks. The members of the genus 
Poliornts (Butastur) are found in Eastern and South- 
Eastern Asia with one exception, which inhabits 
Abyssinia and the adjacent countries of Africa, whereas

the genus Asturina (Melerax)* inhabits tropical j 
America, and one species occurs in the West Indies. — 
Their habits approach nearer to those of the Buz- 
zards than of the Hawks, and they are probably more — 
closely allied to the former than to the latter. In the 
next 
Case, No. XXXIV., 
we arrive at the true Hawks, a large family of nine 
genera, distinguished by their short wings and elon- 
gated tails. They are very widely distributed, some 
member of the family being found in almost every 
part of the world. A few of the more remarkable 
forms are Uvospizias wallacit from Lombock, and 
CU. natalis from Christmas Island ; Leucospizias albus, 
the Great White Hawk of Australia, and ZL. leucosomus, 
the Lesser White Hawk of New Guinea, are remark- 
able as being the only Hawks which have pure white 
plumage. OU rujitorques, in 
Case XXX\V., 
is a beautiful and rare bird from the Fiji Islands, and 
UY. melanochlamys is striking for the lovely contrast of 
its rufous and black colours. U. sardinia (Gurney),
