from the Sudan ; it is known from various localities in 

 Uganda, and was also obtained by Boyd Alexander at 

 several places between Baucbi in Northern Nigeria and the 

 headwaters of the Welle river. It is distinguished from 

 T. a. albiscapulata by the red, instead of black, bases to the 

 tail-feathers.

This bird is abundant in Uganda, but has not been 

 recorded previously so far north as Lado. Alexander 

 obtained it on the Welle river. 



Thamnolaea coronata kordofanensis.

There are no examples referable to this form in the 

 Museum or in the Butler collection, nor are there any 

 examples of the typical T. c. coronata from Togoland 

 (Reichenow, O. M. 1902, p. 157). We have been unable 

 to find the type of T. claudi Alexander (Bull. B. O. C. xvi. 

 1906, p. 12-i) from Lake Chad, which was afterwards stated 

 by the describer (Bull. B. O. C. xxiii. 1908, p. 16) to be the 

 female of T. coronata.

This is a bird of restricted distribution confined to the 

 Lado Enclave, where it was discovered by Emin, and to 

 the upper valley of the Welle, whence Alexander obtained 

 an example. 



A pair shot by me at Kajo Kaji are now in the Gordon 

 College Museum {A. L. B.).
