THE BIRDS OF AUSTRALIA. 
recognisable, all of which I regarded as subspecies, and therefore I relegated to 
subspecific rank only the Tasmanian, South-west Australian and the North- 
western form argenteus. Thus 
Cracticus torquatus torquatus (Latham). 
Queensland, New South Wales. 
Cracticus torquatus olindus Mathews. 
“ Differs from C. t. torquatus in being darker above and smaller in the 
wing : 133-138 mm. ; typical, 142-154 mm. (Olinda) Victoria.” 
Victoria. 
Cracticus torquatus ethelce Mathews. 
“ Differs from C. t. torquatus in being much fighter above. Eyre’s 
Peninsula, South Australia.” 
South Australia. 
Cracticus torquatus cinereus (Gould). 
Tasmania. 
Cracticus torquatus leucopterus Gould. 
West Australia. 
Cracticus torquatus argenteus Gould. 
North-west Australia. 
I later added 
Cracticus torquatus colletti. 
“ Differs from the type (the bird in the British Museum, marked type by 
Gadow) of C. t. argenteus in its altogether smaller size and in having much 
less white on the tip of the tail ; wing 140 ; culmen 37 ; tarsus 30 mm. 
(May River), Northern Territory.” 
Northern Territory. 
and 
Cracticus torquatus colei. 
“ Differs from C. t. olindus in its lighter back and wing-coverts, and from 
C. t. torquatus in its smaller bill. Mallee, Victoria.” 
Mallee, Victoria. 
In my 1913 “ List ” I recognised Cabanis’ genus Bidestes and admitted 
the preceding subspecies with the exception of C. t. colletti, which I questionably 
placed in the synonymy of C. t. argenteus, accepting Witmer Stone’s type 
locality of Port Essington. 
Campbell recently had the pleasure of examining birds from the King 
River, which he regarded as typical of Gould’s species, and wrote : “ Three 
<$ (1 immature). Length 265-282, wing 146-147, culmen 38-39, tarsus 28 mm. 
In the common species ( destructor or torquatus ) the black on the head dissolves 
into the dark back, whereas in argenteus a deep black head is clearly defined
