similis H. nova; zealandice, sed valde minor : supra magis cinereus : caudse fasciis angustioribus et obscurioribus : 
subtbs pallidior, distinctius striatus et maculatus. 
$ maris staturam conspicue superans. 
Juv. a specie prsecedente baud distinguendus, sed subtus obscurior. 
Adult male. Upper parts generally greyish black, darkest on the head and nape; shoulders, scapulars, and 
small wing-coverts narrowly barred with greyish white, the back and upper tail-coverts with small crescentic 
hands of rufous ; throat yellowish white ; ciliary bristles, ear-coverts, and the facial streak black ; a line 
over each eye, and the sides of the neck, reddish brown, varied with fulvous and black ; breast and sides 
fulvous, varied with reddish brown, and largely marked with black. On the breast each feather has a central 
dash of black ; and on the sides these markings assume a triangular form, giving a spotted character to the 
surface of the plumage. The wing-feathers are marked, on their outer weh, by narrow transverse hands of 
greyish white ; and the tail-feathers, which are black with a purplish reflection, have a series of seven narrow 
white bars disunited at the shaft, and are tipped with rufous brown ; axillars dark rufous brown, with a 
series of round white spots on each web ; abdomen and vent pale fulvous ; tibial plumes rufous, with black 
shaft-lines. Bill black, white at the base of lower mandible ; irides very dark brown ; cere, lores, and 
eyelids bright lemom yellow, slightly tinged on the cere with green ; legs and feet paler yellow and more 
tinged with green ; claws black. Extreme length 16 inches ; extent of wings 26 '5 ; wing, from flexure, 9 ; 
tail 6'5 ; tarsus 2'25 ; middle toe and claw 2’3 ; hind toe and claw l - 3 ; bill, along the ridge '85, along the 
edge of lower mandible 1. 
Adult female. Differs from the male in its somewhat larger size and in the darker and richer colouring of its 
plumage ; hut in other respects the sexes are alike. Extreme length 16' 75 inches ; wing, from flexure, 10 ; 
tail 7'7 ; tarsus 2 - 4. 
Young. The young of this species bears a general resemblance in its plumage to that of the preceding bird ; 
but on a close comparison it will be observed that the brown of the underparts is darker, while the spotted 
markings on the sides are rather more conspicuous. The tibials, moreover, are of a brighter rufous, and are 
crossed with numerous arrow-shaped marks of brown. 
Nestling. Covered with bluish-grey down ; hill black ; tarsi and toes leaden grey.
