color is broad and most conspicuous, is very narrow and 

 much less distinct in T. vlrgo. 



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.

 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 Region by Capt. 

 Shelley (Ibis, 1883, p. 326).

It is already a matter of record t that during the year 1884

 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
