It is quite possible that a good series of specimens will show that 

 T. ambiguus, Boc, is not different from true T. decipiens, the 

 former being only somewhat smaller and more grey on the sides of 

 the head or cheeks ; but I find that in two specimens from Sobat 

 {Emm Paslia), one mentioned below and the other in the Tristram 

 Collection, the amount of grey on the cheeks is rather variable, 

 and although the difference in size seems constant, I do not think it 

 is sufficient to indicate specific difference.
