in trees upon a bed of chips, leaves, and insect-deébris. JZ 
latifrons, of Borneo and the Nicobars, has a much wider frontal 
band; JL melanoleucus of Assam and Cachar, JL erythrogenys 
of the Philippines, and JZ sinensis of China are quite white 
below; but the second has black thighs and the third a white 
nape, a character shared by JL eutolmus, ranging from India 
to Cambodia, wherein the throat and abdomen are chestnut. 
Poliohieraxz semitorquatus, little bigger than the foregoing, inhabits 
North-East and South Africa, the male being blue-grey with white 
forehead, cheeks, nape, rump, under parts and markings on the 
remiges and rectrices; P. insignis of Borneo and Siam is 
larger, with black shaft-stripes, but no white collar. The females 
have the mantle, and in the last-named the crown, chestnut. The 
African species rarely soars, but haunts low trees and bushes, occa- 
sionally flocking, and feeding on mice, small birds, lizards, and 
coleopterous insects.  Spiziapteryx circumeinctus, of Chili and 
Argentina, 1s brown above and whitish below, with numerous 
dark streaks; the white eyebrows meet at the nape, and white 
spots and bands mark the remiges and lateral rectrices. 
Dissodectes ardesiacus, of Arabia, North-East and West Africa, 
is slate-coloured with dark shaft-stripes, the wing-quills being 
brown and the tail interruptedly barred with whitish. LD. dickin- 
sont of Benguela, the Shiré and Rovuma valleys, is brown with 
pale head and white rump; JD. zoniventris of Madagascar has 
dark bands on the mantle and on the white under parts. Hiera- 
cidea (Harpa) novae zealandiae, the Quail Hawk of New Zealand 
and the Chatham Islands, is dark brown with rufous and grey 
barring above; the crown and nape being blacker, the tail shew- 
ing eight whitish bands, and the creamy-white lower surface and 
fulvous thigh-region exhibiting streaks of brown. It may be seen 
soaring over the plains and lower hills, hoverimg with expanded 
tail, or pouncing like an arrow on the rodents, birds, and lizards 
which form its food. Insects too are captured on the wing, and 
poultry fiercely attacked. The cry is screaming; the eggs resemble 
those of the Peregrine Falcon, and are deposited in hollows scraped 
on rocky ledges, or occasionally in rough nests among thick 
creepers. A smaller and bolder race has been termed H. ferox 
or brunnea, the Bush-Hawk. H. berigora of Australia and New 
Guinea has brown upper parts, with rufous markings that become 
bands on the white-tipped tail, creamy under parts streaked with
