Genus — ALPHACINCLA. 
Alphacincla Mathews, Austral Av. Rec., 
Vol. II., pt. 5, p. 110, Sept. 24th, 
1914. Type (by original designation) Colluricincla woodwardi Hartert. 
I have diagnosed this genus : “ Differs from Colluricincla Vigors and 
Horsfield in having a flat head and a long thin bill equal to the length of the 
head ; lower bill with wide interramal space ; nostrils in a groove with no 
feathers.”
