Dear Brewster: 
At length T have completed my examination of the specimens

nemoralis, and Coccothraustes abeillei gratus. If you wish 
to publish these birds in advance of the paper I will send you 
the notes I have made upon their relationships to the most 
nearly allied forms. Otherwise I will keep them and insert 
them in the paper, I have taken descriptions of the types so

me, unless you wish to make the descriptions yourself. When
