either side of the head to the hind neck. Back, olive green, 

 somewhat brighter on the upper tail coverts. The feathers of 

 the top of the head lengthened into an erectile crest. 



Under surface. — Chin, throat, and upper breast, black. 

 bounded on either side of the neck by a broad patch of white; 

 rest of the under surface bright yellow. 



Wing. — Primaries, secondaries, and wing coverts, dull 

 black; all, except the first primary, narrowly edged with light 

 grey. The outer webs of the secondaries washed with olive 

 green. 



Tail. — Two central feathers dark grey, the two outer fea- 

 thers with the outer webs white, and the inner grey largely 

 tipped with white, the rest with inner webs dull black, outer 

 webs grey. 



Legs and feet, dark brown; bill, black; iris, reddish brown. 



Measurements. — Total length of skin, 165 m.m.; Wing, 82 

 m.m.; Bill, 16 m.m. 



The female differs from the male in being slightly less in 

 all measurements, in having the chin grey, and the throat and 

 upper breast olive green, instead of black, and in having the 

 bill dark brown colour, with lighter edges. The young re- 

 semble their parents from the nest. 



Distribution. — All parts of South Australia in which 

 Eucalypti are found, except Kangaroo Island and Eyre's Penin- 

 sula. It has been recorded from as far north as Moolooloo 

 in the Flinders Ranges, and as far south as Penola. Nearly 

 allied sub-species inhabit the whole of the eastern and northern 

 parts of the Continent, Western Australia, having a species 

 of its own. No species occurs in Tasmania. 



Habits. — This handsome bird is still commonly, though 

 sparsely distributed throughout the Adelaide parks and gar- 

 dens, though from its retiring habits it is not often recognised, 

 but anyone familiar with its mournful whistle can find a pair in 

 almost any part of the park lands. They are common in the 

 hills about Blackwood and Belair, but less so in the higher more 

 thickly timbered parts of the Ranges. They are very local 

 birds and a pair once located can be found about the same 

 situation year after year, and all the year round. 



In the Autumn and winter each pair is generally accom- 

 panied by last season's brood, the latter being driven away at 

 the approach of the next nesting season. They usually keep
