and long. 26°, but found no nests. They do not occur about 

 Potchefstroom. 



128. BucERos FLAViRosTRis, Rupp. Yellow-billed Horn- 

 bill. 



Male :— Total length 21 inches, bill 3^, tarsus 2, wing 8^, 

 tail 8^ ; iris tawny yellow, bare skin round the edge dark 

 pink, bill bright yellow with brown margins. 



This Hornbill feeds principally on fruits ; it is tolerably plen- 

 tiful throughout the bush-country, and is mostly found in small 

 companies. 



129. (L. 455 & 457.) Buceros nasutus, Linn. Nasique 

 Hornbill. 



Immature: — Total length 18 inches, bill 2|, tarsus 1|, wing 

 8, tail 8;| ; upper mandible tawny white, except the tip, which, 

 with the lower mandible, is reddish brown. 



This species is common along the Limpopo ; and I have also 

 received it from the Megaliesberg, a range of wooded mountains 

 about seventy miles from Potchefstroom. 



Like the preceding species, this Hornbill is a fruit-eater, lives 

 in small companies, and has a dipping flight. 



I was much surprised to find one of these birds, perched on 

 the top of a tall tree, singing very prettily, with the voice of a 

 Thrush ; I could scarcely believe my ears until I had watched 

 the bird for a considerable time ; at last he flew away and the 

 woods were again silent. 



130. (L. 469.) Trachyphonus cafer (Vieill.). Le Vail- 

 lant's Barbet. 



Male: — Total length 9^- inches, bill IfV, tarsus 1:^, wing 4^, 

 tail 3| ; bill pale green ; stomach contained insects and 

 fruits. 



The specimen sent is the only one I have met with ; it was 

 shot by a friend amongst the trees on the banks of the Limpopo, 

 and appears to have been solitary.

 species recently published by the Messrs. Marshall in their 

 monograph of the Capitonida. — J. H. G.]
