356 Mr. A. L. Butler on the 



161. Halcyon chelicutensis (StanL). 



a. S ■ Kaka, White Nile, Feb. 24, 1902. 



I have only seen this Kingfisher a few times, in the 

 neighbourhood of Kaka and Fashoda. On these occasions 

 it was observed singly, perched on a tree or stump in a 

 clearing on the look-out for insects. 



162. Colius macrurus (Linn.). 



a. $ . 20 miles west of Omdurman, Jan. 2, 1903. 



The Blue-naped Coly is common and evenly distributed 

 along both the White and Blue Niles, but does not seem to 

 range much further north than Khartoum. In the gardens 

 of that town it is often seen, especially when the dates, to 

 which it is very partial, are ripe, and it breeds in the lime- 

 trees in the early spring. Except in the nesting-season, it 

 is always met with in flocks of from ten to twenty indi- 

 viduals. These parties feed in the closest company, and the 

 birds all take flight from a tree simultaneously. Their flight 

 is straight and rapid, and on the wing they utter a shrill little 

 trilling whistle. 



In captivity these Colies become very tame, and thrive 

 well on a diet of dates and figs. 



163. Colius leucotis Riipp. 



a. ? . R. Setit, May 12, 1903. 



Widely distributed. I have shot it on the Setit River, on 

 the Bahr-el-Ghazal, and at intermediate points on the Blue 

 and White Niles. I do not remember to have seen it 

 frequenting gardens and date-palm groves like the blue- 

 naped species. 



164. Schizorhis zonura Riipp. 

 a. S • Gallabat, April 15, 1903. 



The Grey Plantain-eater is generally to be found in 

 small parties among the tall trees in the neighbourhood of 

 Gallabat and on the Upper Atbara. I have not myself met 

 with it elsewhere. 



165. Centropus monachus (Riipp.). 



This Lark -heeled Cuckoo is very common on the marshy 

 portions of the White Nile, and in the "sudd" along
