* Mr. Brewster has recently shown that P. plumbea is the female of P. mela- 

 nura, and has at the same tijue sejianited the (Jalifornian bird as P. californica. 

 I have compiled the sjnoiiyiny cf' these species from Dr. Coues's ' Birds of the 

 Colorado Valley ' and from Mr. Brewster's paper (/. c.) ; but as I have not seen 

 a single specimen of either of the species, I have not been able to judge for 

 myself in the matter, and the synonymy will doubtless be subject to revision.
