* NiLTAVA DAViDi La Touchc. 



3 specimens, both sexes, Mengtsze, April, Oct. 



Thayer and Bangs (Bull. M. C. Z., 1909, 52, p. 141) overlooked 

 La Touche's name when describing their Niltava lychnis. There is, 

 however, a chance that their bird from Hupeh is subspecifically dis- 

 tinct from N. davidi La Touche, which came from northwestern 

 Fokien. The two males in the present collection agree almost exactly 

 with La Touche's d'escription of N. davidi and differ from the type of 

 N. lychnis in having the crown brighter blue and the chin, sides of the 

 head and throat washed with dark, bluish purple, whereas in the type 

 of N. ly chilis these areas are dead black.
