No. 1.] THE AUSTRAL AVIAN RECORD 21 



The bill is very long and. narrow, the exposed por- 

 tion measuring 16 mm. Wing measurement of type 

 107 mm. Type no. 1464 $ , Coomooboolaroo, Dawson 

 River, Queensland. 



This species differs from both the C. plagosus group 

 and the G. basalis group. It approaches the latter in 

 upper-coloration, but is entirely different in the under - 

 surface barring ; the throat is crossbarred whereas in 

 C basalis it is obscurely longitudinally streaked. It 

 differs from the former in its general coloration and 

 especially in its tail coloration. 



As regards Eudynamys I find that the North-western 

 birds are easily separable from the East coast ones by 

 their smaller size, the average wing measurement of the 

 former being 200 mm., of the latter 220 mm. This form 

 I propose to call : 



Eudynamys orientalis subcyanocephalus, subsp. n., 



type no. 1470, Parry's Creek, North-west Australia.
