Iris yellow brown, clouded witli darker colour near 

 the pupil, bill dull red, legs dusky. 



A highland species, but by no means very common iii 

 the country traversed. It was most frequently seen 

 around Senaf^ in small flocks, probably families, of about 

 four to eight birds. I occasionally met with it in the

 the means of procuring a specimen at the time. 



The measurements of a female are : — Wing 11 "4 in. 

 tail 10 '5; bill, nostril to point 4'1, gape to point 4"7; 

 height of bill 1 '4 ; tarsus 1 '3 : whole length about 23 in. 



By Brehm, "Keise nach Habesch," p. 219, and by 

 Hartlaub, "Syst. der Orn. West Afr." p. 164, Buceros 

 Hemprichii of Ehrenberg is considered a synonym of 

 B. nasutus, Hartlaub especially calling it the female. 

 This is evidently a mistake, the female of B. nasutus 

 being the B. hemileucos of the "Symbolae Physicae." 

 Ehrenberg's descriptions are not very good, but the cha- 

 racters of the bills alone serve to show what the birds 

 really are to which they refer. 



It is also as well to call attention to the fact that the 

 subgeneric names, Alophius proposed by Ehrenberg in
