formed an ill defined collar of pale brownish yellow and a slight wash 

 of yellow pervades the under surface. Total length 205 m.m., tail 

 88 m.m. 



Young male. — Like the adult female : occasionally with one or 

 more feathers of the breast distinctly yellow. 



In the adult male the excess in the length of the tail over that 

 of the female is due to a graduated prolongation of the lateral 

 feathers which renders the form of the tail as a whole subfurcate. 



Note on Colluricincla boweri Ram. — 



I take the earliest opportunity of pointing out that the Shrike- 

 thrush, na ned by me C. sibila, is in all probability identical with 

 Dr. Ramsay's species C % boweri.
