The trichroa group, for which Reichenbach proposed Trichroa, has the 
same land of bill, and lias a long wedge-shaped tail, the two central feathers 
a little longer and tliinner, but not attenuate. The biU is shorter than the 
tarsus and the tail is decidedly shorter than the wing. The coloration is 
gi-een above and below, with a blue fore-head and cheeks and, of coui-se, the 
red rump and tail. 
Amblynura, given to qjedlei and cyanovirens, shows a short, stout, heavy 
bill quite uncharacteristic of Erythrura semu stricto, and a short tail, the 
central tail-feathers not attenuate and scarcely longer than the others ; the 
tarsus is longer than the biU, and the wing is nearly twice as long as the tail 
instead of beuig shorter. The striking green coloration is varied by a red 
head and face and a blue throat, the red rump and tail being still retained. 
In the second species the blue extends on the upper chest and on the back. 
Acalanthe, based on psittacea alone, has a similar stout but shorter bill, 
and the tail longer and wedge-shaped ; the central feathers longer and thinner 
but not attenuate. The tarsus is one and a half times the length of the bill 
and the wing is about one-fourth longer than the tail. The red head and 
face is seen, but no blue throat, all being green save the red rump and taU. 
There is thus four distinct groups as regards structm’e : 
Erylhura with long bill, short tail with long, attenuate, central 
feathers. 
short bill, short tail, no attenuate central feathers, 
short bill, long wedge-shape tail, no attenuation, 
long bill, long wedge-sha])ed tail, no attenuation, 
short biU, short wedge-shaped taU, no attenuation. 
The last is not satisfactorUy known, only one specimen being examined.
