No. 5144. a. ,^ . North-west of Lake Tanganyika, 

 3000 ft., 7th Jan. 



Iris dark hazel ; bill dark brown ; feet dark grey. 



The occurrence of the Southern Rock-Sparrow on the 

 Upper Congo carries its known range a little further to the 

 north. It has been recorded as far north as Ussure on 

 the east and Leopoldville on the west. 



Passer diffusus (Smith).

Passer griseus Reich, iii. p. 230 (1904). 



No. 5163. a. ? . East of Kasongo, Upper Congo, 

 2000 ft., 28th Jan. 



Iris brown ; bill black ; feet brown. 



Presumably this bird should belong to the form mentioned 

 by Dr. Reichenow under the name of P. griseus ugandce ; 

 but the wing measures 82 mm. I agree with the conclusions 

 arrived at by Captain Shelley and include all the four forms 

 that have been recognised under the present heading, as I 

 am unable to find any characters by which they may be 

 separated. 



Chrysomitris frontalis. 



Spimis citrine lloides frontalis Reich, iii. p. 275 (1904). 



Nos. 5020, 5026. a, b. (^ ? . Mfumbiro Volcanoes, 

 5000 ft. 



Iris, bill, and feet brown. 



A large series of this handsome Siskin was collected by 

 the Ruwenzori Expedition. All the males have the yellow 

 frontal band narrowly bordered anteriorly with black. In 

 the male collected by Mr. Carruthers this character is scarcely 

 apparent, but in other respects it agrees. The black markings 

 on the upper parts vary greatly among specimens from the 

 same locality and are no doubt a sign of age, the oldest males 

 having the top of the head and back bright olive-green with 

 very narrow black shaft-streaks.
