a, S Nampoung, 19th February 1875. 



The Nampoung is a fine mountain stream running through a deep glen and 

 defining the eastward limit of the Chinese frontier. A level flat on its hanks is 

 covered with magnificent forest trees, with a clear undergrowth, in strong contrast 

 to the tangled mass of vegetation in the mountain forests ahove. This spot was the 

 resort of a diversity of small hirds, most numerous among which were Reguloides 

 and FericrocotuSi and associated with these was this species of Dicceum.

 c. S Tamilone, 6th February 1868. 



This species has a very close resemhlance to C, phcenicopterus^ Lath., especially 

 when the yellow- green is well developed on the forehead of that species, in which, 

 however, it is never so hright as in the present hird. It is distinguished from 

 C. phcenicopterus hy its hrighter greenish-yellow caudal hand, hy its generally grey 

 upper tail-coverts, and hy the purer grey of the abdominal region, but it tends to 

 blend with C. phoenicopterus, in the same way that the latter does with C. chlori- 

 gaster, and it is probable that an extensive series of specimens of the three 

 species, taken from the centres and extreme limits of their areas of distribution, 

 would show that they all lead into one another.
