Immature birds of this exceedingly variable species diti'er consider-

PLATYSTEIRA CRYPTOLEUCA Oberholser. 



Plati/stelntcryptoleiim Oberholser, Proc. U. S. Nat. Mus., XXVIII, 190.5, p. 91 S 

 (Useri River, plains of Mount Kilimanjaro, British East Africa). 



Specimens from Mombasa, recorded by Doctor Holland as Platy- 

 steira 2)elfat((,'' agree with the type of cryptoleuca in having the large 

 concealed patch of white on the nape, but both male and female some- 

 times have concealed white spots on the rump, from which it appears 

 that their al>sence is not constantly diagnostic of cryptoleucu, as 

 supposed.
