shades " ( W. Davison). Total length 7 inches, culmen 0*8, wing 

 2-95, taU 2-7, tarsus 1-15. 



In the two specimens from Wimpong in the British Museum, the 

 lores, eyebrow, sides of face and chin are pure white ; aud in Mr. 

 Hume's examples from the same locality the same curious diffe- 

 rence of plumage is exhibited, and some of them even had a broad 

 white collar on the back of the neck. This difference in coloration 

 is probably seasonal ; and any one studying the species should con- 

 sult Mr. Hume's paper on T. crispifrons (Str. F. 1877, pp. 87-90).

* In the absence of an examination of Mr. Blyth's types, I have carefully 

 compared our specimens with the description of the species, and agree with Mr. 

 O ates as to his identification.
