Order ACCIPITRES. 
Fam. FALCONID*. 
Germs CIRCUS. (Common to all parts of the world.) 
Circus gouldi, Bonap. New-Zealand Harrier. “ Kahn.” 
(Case II. Nos. 58; 59; and 62 : male; female, and young ; 
No. 62, devouring a Tui.) 
This species has a wide geographical distribution, being 
met with also in Australia, Tasmania, and as far eastward as 
the Fiji Islands. It hunts on the wing, performing wide circles 
at a low elevation from the ground, and sailing over meadows, 
fern-land, or marshes in quest of lizards, mice, and other 
small game. It nests on the ground or in a tussock, and lays 
from two to four perfectly white eggs, ovoido-conical in form. 
Genus HARPA. (Peculiar to New Zealand.) 
1. IIarpa novas zealandi^e, Gmelin. Quail-Hawk. “ Ka- 
rearea.” (Case X. Nos. 19 and 20, adult and young; 
Case IX. No. 11, very finely marked adult female.) 
2. Harpa ferox, Peale. Sparrow-Hawk or Bush-Hawk. 
(Case II. Nos. 45 and 57, the latter devouring a King¬ 
fisher.) 
These Tree-h alcons somewhat resemble an Australian 
genus, but arc sufficiently differentiated to form a distinct 
genus. The Quail-Hawk is very seldom met with in the North 
Island ; and both species are far less numerous than formerly.
