Expedition to the White Nile. 265 



72. Melanobucco vieilloti (Leach). 

 Only observed at Kawa. 



Adult. Iris dark brown ; bill, legs, and feet black. 



73. Trachyphonus margaritatus (Riipp.) . 



We only observed this species between Shebesha and Jebel 

 Auli. In this district it was met with occasionally, attracting- 

 attention by its habit of sitting on the top of a tree and 

 uttering a fine clear piping cry. It also gives vent to a 

 loud and somewhat harsh ''cheouw/' which must, I think, 

 be an alarm-note. 



Adult. Iris hazel ; bill dark pink ; legs and feet dai'k 

 slate-colour. 



74. Campothera nubica (Gm.). 



The bills of my specimens are longer and stouter than 

 in those from Abyssinia in the Tring collection. Although 

 we never saw a Woodpecker^s hole in any tree, the birds 

 were not uncommon, this species being the most numerous. 

 They have a very " bunched-up " appearance when on a 

 trunk. On April 20th I Avatched two females chasing each 

 other vigorously and calling harshly, the reason for which 

 conduct was not apparent. 



Adult. Iris bright red ; bill horn-colour ; legs and feet 

 dark olive-green. 



75. Iyngipicus obsolettjs (Wagl.). 



Only one specimen observed. This was obtained at Gerazi 

 on April 30th. 



Adult. Iris light red ; bill horn-colour ; legs and feet very 

 dark olive-green. 



76. Mesopicus goertan (P. L. S. Miill.). 



This species, which is much shyer than Campothera nubica, 

 was uncommon, two or three being observed at Shebesha and 

 Gerazi, and one near Jebel Auli, where there are very few 

 trees of any size. 



Adult. Iris dark brown; bill light slate-colour at base, 

 dark at tip ; legs and feet slate-colour.
