190 BRITISH BIRDS. 



Coloration of Mouth. Inside, orange. A black spot 

 on each spur of the base of the tongue, and another, 

 brown and more diffuse, situated subterminally. The 

 latter disappears completely 4-5 days after the chick 

 is hatched, which accounts for the fact that it was not 

 noted by Mr. Pycraft (c/. antea, Vol. I., p. 130).

 N.B. — It is possible that the scanty pre-pennse which form

 tract in this species is worthy of note.
