Mr. W. Brewster on the 
color is broad and most conspicuous,, is very narrow and 
much less distinct in T. virgo. 
As to measurements, the new species appears to me to 
be altogether a somewhat larger bird. Thus the length of 
the wing is 122 millim. in T. virgo, and 119 millim. in T . 
bicolor; the length of the tail is 85 millim. in T. virgo , 
but only 75 millim. in our specimen of T. bicolor. 
The locality in Eastern Equatorial Africa where the 
unique specimen (at present in my collection) was shot by 
Dr. Emin Bey he names “ Djanda.” It is the most northern 
point where the genus Tympanistria has been found in the 
eastern territories of the African continent. 
As to T. bicolor (=fraseri , Bp.), the reader will find all the 
necessary information in the elaborate and most interesting 
paper on the Columbidse of the Ethiopian Begion by Capt. 
Shelley (Ibis, 1883, p. 326).

swainsoni). By William Brewster* *. 
It is already a matter of record f that during the year 1884 
Mr. Arthur T. Wayne and I found Swainson’s Warbler 
in some numbers near Charleston, South Carolina, where 
upwards of fifty specimens were taken, including the pre¬ 
viously undescribed young in first plumage. But although 
we ascertained beyond all doubt that the birds bred there, 
we utterly failed to find the nest, or even to learn anything 
definite regarding its probable character and position. 
In May of the present year I visited Charleston for the 
third time, and with Mr. Wayne spent several days wading 
about in the swamps in the hope of stumbling on the prize. 
But the birds (perhaps thinned by our merciless collecting
