HOODED ROBIN. 
for north-western specimens, writing : “ (North’s) conclusion is erroneous. If 
we compare a series of north-western examples with a series of south-eastern 
specimens we find : (1) that the former are smaller, wings averaging 5 to 8 
mm. shorter ; (2) that generally the former have more white in the tail ; 
(3) that the white on the under side is purer, more snowy ; (4) that the 
females are a little lighter on the upper side.” 
That these were only subspecies w T as certain when I made up my 
“ Reference List,” but with the large number I was able to subdivide the 
species into five subspecies, instead of two only. These were Petroica 
cucullata cucullata (Latham), New South Wales ; P. c. vigorsi Mathews, 
“ smaller wing av. 97 against typical 101 mm.,” Victoria ; P. c. 
westralensis Mathews “ again smaller 94 mm. wing av. and 'with less 
white on the greater wing-coverts and outer edge of the secondaries,” 
South-west Australia ; P. c. picata Gould, North-west Australia ; and 
P. c. subpicata Mathews, “ larger than picata and duller than cucullata : 
av. wing 93 mm. ; wing av. of picata, 90 mm.,” Northern Territory. 
Zietz then separated Melville Island specimens under the name Petroica 
c. melvillensis , “ smaller than P. c. subpicata, wing 85 mm. only.” 
It will be seen that practically the only differences are in size, but as 
these are constant and graded the six races should be recognised.
