BROWN SCRUB-WREN. 
Sericornis humilis was known from Tasmania and the island of Bass Straits 
for many years, and then in 1896 Legge described a new species from the Kent 
Group as Sericornis gularis. This was not easily recognised, and when I made 
up my “ Reference List ” I allowed it as a separate species, but called it 
S. frontalis, concluding that Vigors and Horsfield’s type which was in bad condi- 
tion might have come from that group as they had specimens of some birds 
from that locality. Then S. humilis was also allowed as a distinct species, 
but I noted that it was separable generically to workers who did not agree 
to large genera and proposed for it the genus name Tasmanornis . 
In 1913 White and Meilor described the Flinders Island form of humilis as 
Sericornis flindersi, noting it was only a new subspecies but giving no differential 
characters. They wrote “ That Flinders Island yielded a new Sericornis is 
not a surprise, when so many of the islands in Bass Strait have their own varieties 
of this widely dispersed genus. Not uncommon. Found in the thick under- 
growth on mountain sides and in the deep gullies.” What they meant by the 
first statement is not clear, as Legge’ s S. gularis was the only “ species ” named 
in this genus from the islands in Bass Straits at that time and no varieties had 
been named at all. Perhaps they had in mind A. G. Campbell’s essay. 
Immediately afterward, however. Cole named a form from the Forsyth Island 
in the same (Furneaux) group as Flinders Island, calling it Sericornis insularis 
and giving as distribution “ Forsyth, Cape Barren and Clarke Islands,” but no 
comparison was made in this instance either. The next year Mr. A. J. Campbell 
gave me the type of S. gularis Legge and I was enabled to recognise that it 
was a form of humilis and at the same time I named : 
Tasmanornis humilis tregellasi. 
“ Differs from T. h. humilis in being lighter above.” 
King Island. 
Thus at the present time there is : 
Tasmanornis humilis humilis (Gould). 
Tasmania. 
Tasmanornis humilis gularis (Legge). 
Kent Group, Bass Straits. 
Tasmanornis humilis flindersi (White and Meilor). 
Flinders Island, Furneaux Group, Bass 
Straits. 
Tasmanornis humilis insularis (Cole). 
Forsyth Island, Furneaux Group, Bass 
Straits. 
Tasmanornis humilis tregellasi Mathews. 
King Island, Bass Straits.
