THE BIRDS OF AUSTRALIA. 
in one genus Gorvus. The name in use for the Raven was Corone australis as 
of Gould, not Gmelin. As such usage was incorrectj I renamed this species 
Gorvus marian'je. 
I then arranged the species as follows :— 
Gorvus coronoides coronoides Vigors and Horsfield. 
New South Wales. 
Gorvus coronoides ceciloe Mathews. 
“ Differs from G. c. coronoides in its smaller size, wing 355*6 mm. (the type of 
G. c. coronoides 361 mm.) (but the average is over 370 mm.). (Napier 
Broome Bay) North-west Australia.” 
North-west Australia. 
Gorvus coronoides perplexus Mathews. 
“ Differs from G. c. coronoides in its much smaller size ; wing 314-327 mm . 
Perth, West Australia. 
South-west Australia. 
This referred to the Crow with snow-white bases to the feathers, accepting 
Vigors and Horsfield’s name, following Sharpe. 
I then allowed the Small-billed Crow vith three subspecies: 
Gorvus hennetti hennetti North. 
New South Wales, South Australia. 
Gorvus hennetti honhoti Mathews. 
“ Differs from G. b. hennetti in its smaller size generally; wing 295 mm. 
Murchison, West Austraha.” 
West Australia. 
Gorvus hennetti queenslandicus Mathews. 
“ Differs from G. h. hennetti in having a deeper and stouter bill and thicker 
tarsi. (Dawson River) Queensland.” 
Queensland. 
For the Raven I used G. mariance and made four subspecies: 
Gorvus mariancB mariance Mathews. 
New South Wales. 
Gorvus mariance mellori Mathews. 
“ Differs from G. m. mariance in its smaller size (wing 326—330 mm.), and from 
G. h. hennetti in the grey bases to the feathers. (Angas Plains) South Australia.” 
Victoria; South Australia; South-west 
Australia. 
Gorvus mariance halmaturinus Mathews. 
“ Differs from G. m. mellori in its smaller size; wing 291 mm. Kangaroo
