Adult male. Resembles C. aurituin in general plumage and 

 appearance, but may be at once distinguished by having a wide 

 and well-marked white band across the back of the head between 

 the car-coverts and no white on the basal part of the outer tail- 

 leathers ; moreover the white of the throat extends further down 

 towards the chest, and the plumage of the head and neck appears 

 to be somewhat darker. It is impossible to say certainly how 

 many tail-feathers there may have been originally, as the unique 

 type specimen is in very bad condition and the tail-feathers are all 

 loose. Capt. Elwes, in the original description, gives the number 

 as 20, but the plate represents 22. There are now 19 to be found, 

 one on the left side being absent ; but it appears to me that the 

 two central pairs are wanting, and that the full number is 24, as in 

 C auritum.
