[The series now sent by JNIr. Jackson shows that the two 

 typical specimens, described by me in 1891, were both young- 

 birds. The white patch on tiie cheeks and the white markings 

 on the throat become nearly or entirely obsolete with age, 

 so that these cannot be regarded as specific characters. The 

 white forehead also disappears with age, and the head 

 becomes like the back. The only differences between /S. alhi- 

 frons and S. burtoni consist in the more uniform appearance 

 of the upper surface and the narrower and browner stripes 

 on the sides of the body. In S. burtoni the upper surface is 

 mottled with dark brown centres to the feathers, and the 

 streaks on the flanks are black and very broad. 



The name of S. albifi'ons is certainly unfortunate, 

 having been founded on characters peculiar to the young 

 bird. It has also apparently misled Mr. C. W. Richmond, 

 who has compared specimens from Kilimanjaro with the 

 description of my C. albifrons and has named Dr. Abbott's 

 bird Crithayra kilimefisis. I am afraid that Serinus kilimensis 

 (Richmond) is only the adult bird of my C. albifrons. —
