Typical T. albirostris has the bill buff and swollen at the

 From the Upper White Nile I have a specimen in almost 

 full plumage, with a smooth brown bill, which might belong 

 to any of the three races. 



T. intermedins has the bill smooth and red in the adults. 



T. scioanus has the bill red and swollen at the base in full 

 adults, 



A typical specimen in my own collection, labelled '' (^ . 

 1-11-79: Dambi (Antinori) ,•"' is apparently f ally adult. The 

 bill is recorded as red, but is now buff with a dark tip. The 

 bill in all these forms is stouter and slightly shorter than in 

 the S. -African species.
