August, 1938 
plant. A tabulated statement will show the distinctive 
character of the new species better than narrative : 
A. Ledwardii. 
Dorsal sepal abruptly mucro- 
nate, with a short depressed 
point. 
Lateral sepals parallel, not 
much longer than the label- 
lum, each sepal prominently 
trifid at the apex. 
Petals short and broad. 
Label lum convex below, 
above concave nearly to the 
blunt apex; ridges absent, but 
the anterior part of the disc 
very papillose; margins in- 
curved and irregularly serru- 
late. 
A, fornicatus. 
Dorsal sepal acuminate with 
a long, fine point, straight or 
upturned. 
Lateral sepals connivent 
under the labellum, then 
diverging into long, fine points. 
Where the sepal becomes fila- 
mentose, at the base of the 
filament, are two small teeth, 
but sometimes these are rudi- 
mentary or absent. 
Petals short and usually nar- 
row. 
Labellum concave below, 
above with a median channel 
between two high papillose 
ridges; margins recurved; apex 
acute. 
These are the main differences, and they seem to me 
sufficient to justify specific separation. 
Dr. Ledward states that the new plant is rare, and 
has so far only been seen in one locality. He discovered 
it in 1934, but we both felt that further material was de- 
sirable before deciding on its status. During the next 
three years, owing to unfavourable seasons and other 
circumstances, he did not see it. It has now reappeared 
in June, 1938, precisely identical in form with my draw- 
ings of the 1934 specimens. I am glad of the privilege 
of naming it after its discoverer, who has done so much 
in recent years to add to our knowledge of the orchid 
flora of Queensland south of Brisbane. 
The colour of the flowers may be described as chiefly 
a deep purplish or reddish brown. A. fornicatus varies 
from a pale translucent green to dark red-brown, but I 
have never seen it with the suffused purplish tint of the 
newcomer. The basal tubercles of the labellum are as in 
A. fornicatus. 
ORNITHOLOGY OF THE MT. COOT-THA RESERVE 
TAYLOR RANGE 
By N. Jack. 
In presenting the following article, which is the. re- 
sult of observations made over a period of seven or eight 
years, I am not assuming that this district has not been 
explored and checked up by more competent ornitholo- 
gists than myself before now. An attempt has been made, 
however, to present as full a list as possible and to ascer-
