Adult. Crown of the head, hind neck, and upper parts generally clear olive-brown ; throat pure white ; breast 
and abdomen ashy grey, darker on the former, the abdomen and the under tail-coverts tinged with yellow ; 
sides olive-brown, washed with yellow ; wing-feathers dark olive-brown, dusky on their inner webs ; tail- 
feathers and their upper coverts bright rufous, paler on their under surface, the two middle ones tinged 
above with olive-brown. Irides yellow; bill and feet dark brown. Total length 11 inches; wing, from 
flexure, 5'25 ; tail 5 ; bill, along the ridge ‘8, along the edge of lower mandible 1 ; tarsus D25 ; middle toe 
and claw 1'25 ; hind toe and claw 1. 
Young. Birds of the first year differ in having the feathers at the base of the upper mandible, the tips of those 
covering the crown and sides of the head, the small feathers fringing the eyelids, and a broad zone on the 
upper part of the breast bright rufous ; the primary and secondary wing-coverts, and sometimes the secon- 
dary quills, are also largely tipped with the same colour, and the grey ot the underparts is darker, but with 
a tinge of orange-yellow under the wings. 
I N January 1869 I communicated to ‘ The Ibis ’ the description of a new species of Thrush inhabiting 
the North Island, and differing from the South-Island bird ( Turnagra crassirostris ) not only in 
plumage, but in its superior size and more strongly developed bill; and I named it m compliment to 
my friend Dr. (now Sir) James Hector, F.R.S., Director of the Colonial Museum and Geological 
Survey of New Zealand. 
In an editorial footnote to my paper, Professor Newton suggested that this species might be 
identical with one described, in a Dutch work, by Professor Schlegel, four yeais before, without, 
however, any habitat being assigned to it. This opinion has since been verified by a careful compa- 
rison of the specimen I have figured with the type of Sclilegel’s Otagon tanagra in the Museum at 
Vienna ; and under ordinary circumstances the name I have proposed would of course be reduced 
to a synonym. It will be observed, however, that Professor Schlegel has used a common generic 
name to distinguish the bird specifically, while he refers the form to the genus Otagon, established 
by Bonaparte in 1850. As I can see no valid reason for setting aside the generic title of Turnagra
