This endemic Australian genus is difierentiated by its coloration and size 
from the genera Gacomantis and Lamprococcyx. It has the long bill of the 
former and the square tail of the latter, the coloration suggesting evolution 
from the ancestral form of the latter and inclining to its non-relationship with 
the former. Gould named it “ osculans indicating this affinity, placing it 
with the Bronze Cuckoos, afterwards writing : “ MM. Cabanis and Heine have 
estabhshed the above genus for the bird I had called Chalcites osculans, and 
as I have adopted many of the new genera into which the Cucuhdse are now 
divided, I have no alternative but to adopt this one also. The only species of the 
form yet discovered is a larger or more robust bird than the little Bronze 
Cuckoos, and it also differs from them in its colouring.” 
In the Austral Avian Record, Vol. I., p. 3, 1912, I discussed the case of 
Misocalius, pointing out that it was based on Latham’s Cuculus palliolatus, 
and no generic diagnosis given. Consequently it cannot be used for a 
different species.
