the changes of plumage in this species and its allies, but the 

 Jifticulty of arriving at any satisfactory solution of their 

 varied plumages coupled with lack of time have obliged me 

 to abandon the attempt for the moment. There can be 

 hardly any doubt but that the present species and also 

 T. duchailhd Cassin interbreed with some of the allied forms 

 and that the puzzling stages of plumage often to be found 

 among series of these birds^ quite outside the normal 

 changes from rufous to white, can only be accounted for in 

 this way. 



The present collection includes : — 



a. An almost entirely black-and-white adult nuile with 

 the tail white ; and a few chestnut feathers on the rump 

 and mantle. Charada Forest, 3rd of June. 



b. An adult male with the tail white and the mantle 

 almost entirely chestnut. Sombo, near Addis Alam, 

 15th of November. 



c. d. Two adult males with the outer tail-feathers chestnut, 

 the mantle uniform chestnut. Ilolata, near Addis Alam, 

 13th of November, and JNIaroko, Lake Zwai, 16th of January. 



e. An adult male in chestnut-and-black plumage with 

 only the outer webs of the inner quills bordered with white. 

 Jimma, 16th of May. 



/, g. An immature male and an adult female, with 

 chestnut back and short chestnut tail. Uba, 10th of July, 

 and Holata^ 13th of November. 



214. CUYPTOLOPHA UMBROVIRENS. 



Cryptolopha vmbrovirens (Riipp.) ; Erlanger, J. f. O. 1005, 

 p. 683. 



A male example of this Flycatcher was procured in June 

 in the Charada Forest, Kafl'a, at an elevation of 6000 feet. 

 It is unfortunately moulting and in poor condition, but 

 appears to be referable to the typical form of this species 

 described by Riippell from Simen. Examples in the British 

 Museum from Waghar, N. Somaliland (c/. 'Ibis/ ] 910, p.312)
