Adult. General colour above lavender-brown, with a distinct shade 

 of purple on the scapulars and under tail-coverts, which are darker 

 brown; wings dark brown, externally purplish; tail dull purple, 

 with a broad white band at the tip, slightly shaded with lilac ; fron- 

 tal plumes stiff and recurved, black, as also the feathers above and 

 round the eye ; the rest of the sides of the face, sides of neck, throat, 

 and fore neck blackish brown ; hinder part of head and hind neck 



* This figure is apparently made up from Brisson's, and coloured from his 

 description. The result is a tolerably good representation, not of C. cay amis, but 

 of C. hellus of Schlegel (= C. mystacalis, Greoffr.). It is only the fact of the base 

 of the outer tail-fealhers being blue that prevents it from representing C. mysta- 

 calis with accuracy ; and if C hellus were distinct from the latter, which we do 

 not helieve, then Montbeillard's plate ought, apparently, to be referred to it.
