252 BIRDS OF THE DISTRICT OF GEELONG 
Calamanthus. We obtained two of these birds and 
sent the skins to England, where Mr. Gregory Mathews 
declared them to be young birds of a new sub-species 
of the Red-rumped Hylacola, to which he gave the 
vernacular name of Geelong Ground-wren. 
On December 29th, 191 2, I met with another pair 
at Airey's; they were on a piece of scrubby, ferny 
ground on the hillside between Lugg's and the 
Lighthouse. These birds first drew my attention by 
their song, a sweet warbling strain suggesting some- 
what that of the Calamanthus, quite different from 
the harsh note I had previously heard, and delivered 
from the top of a low bush where the bird stood 
perched with tail erect. 
Judging that the headquarters of the species would 
prove to lie somewhere on the barren grass-tree 
country between Wensleydale and the coast, I ar- 
ranged with Mr. Herbert A. Purnell to make a 
walking-tour from the Saddle to Anglesea, on a route 
which would take us through the heart of it. This 
we carried out on September 20th, 191 3, and had 
not gone more than a mile south from Wensleydale 
before we met with our first pair of the birds. Six 
other pairs we observed before nightfall, and of the 
last we found the nest, seeing the bird fly from it, 
a domed structure of grasses placed in a small hollow 
in the ground which the birds had scraped out at 
the foot of a tuft of herbage. It was lined warmly 
with feathers and had an entrance at the side. The 
three eggs were of a purplish white ground-colour
