Descnption, — Similar to 'S', diademata, Verr, but darker especially on the 

 crown and throat. Measurements the same as diademata. 



Distribution. — Yunnan and the Bhamo Hills (originally described from 

 Warabum, E. of Bhamo and not S, Shan States, as entered on label of 

 type specimen.) 



Nesting and Habits. — " It is very Tit-like in its habits and notes, and 

 continuously raises its crest and so reveals the conspicuous white patch at 

 the back of its head. I found several nests during April at Sinlum, Bhamo 

 District, these were all placed between the upright stems of wild raspberry 

 bushes, from 3 to 4 feet from the ground, and were very flimsy affairs, made 

 entirely of some black roots. The eggs, of which two seem to be the usual 

 number, are very like small editions of Copsychus saidaiis, being of a 

 greenish-blue ground-colour profusely spotted, more especially at the larger 

 end, with amber-spots. Average of seven eggs = 'TGx "60, largest = 'SOx'GO 

 smallest ^ "75 X '58.
