68 Capt. G. E. Shelley on the 



Transvaal {Ayres'' ^) ; Umgeni River in Natal [Shelley''); 

 Kuruman (Exton^) ; Gt. Namaqua* and Damara [Andersson^) . 

 CafFraria (Lichtenstein^). 



Dr. Keichenow, at my request, has most kindly examined 

 the type of Buceros leucomelas, Licht., and informs me, with 

 other notes, that the bill is yellow, and that the dark por- 

 tions of the feathers of the lower throat and front of the 

 breast are confined to their sides, and are not shaft-stripes. 

 This, together with the locality, " CafFraria " or Natal, 

 decides conclusively that this species is the true Buceros leu- 

 comelas, Licht. 



26. LOPHOCEROS ELEGANS. 



Toccus elegans, Hartl. P. Z. S. 1865, p. 86, pi. 4'. 



Tockus flavirostris, Sharpe, Cat; Afr. B. p. 9^ (part.); 

 Bocage, Orn. Angola, p. 119^; Elliot, Monogr. Bucerot. 

 pi. 51 (part., Benguela). 



Hab. Confined to S.W. Africa. 



Moconja, Capangombe, Huilla [Anchieta^) in Mossa- 

 medes; Benguela {Mo7iteiro\ Brit. Mus.). Galungo and 

 Loanda {Sala^, Brit. Mus.). 



I would remark that the occurrence of this species in 

 Angola is not absolutely certain, as I believe when Sala's 

 specimens were received that gentleman had been collecting 

 in Mossamedes. It would appear to me more natural that this 

 should be a very local and purely S. African form, being 

 allied to L. leucomelas about as closely as L. damarensis is 

 to L. erythrorhynchus. Both of these I consider to be only 

 just separable as species.
