Subspecific characters. — Differs from all other forms in its much paler 
colouration. Averages slightly less in all dimensions than australis. Head, 
ear-coverts and mantle sky blue ; upper wing-coverts and innermost secondaries 
more or less drab ; lower under surface more distinctly white, the drab on the 
flanks being much restricted or lacking. Female lighter, being olive-brown 
rather than mummy brown on the upper surface. 
The extensive series examined shows intergradation with 
australis on and near the coast about mid-New South Wales. 
Inland, however, cynochlamys appears to range much further 
south. All specimens from localities west of Sydney are almost 
exactly intermediate between cynochlamys and australis.
