286 Mr. C. H. B. Grant on a Culledion of 



Adult. Differs from /. e. erythrorhynchus in having the 

 spots on the wings and tail large and the tail longer, 8|^ to 

 ]0 inches, central feathers and coverts strongly washed with 

 purple on their upper surf ace, rest of plumage as/, e. erythro- 

 rhynchus. 



Young. Plumage as young of /. e. erythrorhynchus, but 

 wing- and tail-spots large and tail longer. 



Range. Natal, Swaziland, Transvaal, Portuguese East 

 Africa^ Matabeleland, Mashonaland, Nyasaland, northern 

 Rhodesia, Belgian Congo (Dikulwe Valley), German East 

 Africa, British East Africa (Mombasa to Rift Valley), Uganda 

 up to the Turkwel River, island of Zanzibar. 



Note. This race retains the black bill of the young for 

 only a short period, apparently assuming the red bill with 

 the first moult. 



The Kakelaar, which occurs in Pondoland (see Shortridge, 

 ' Ibis,' 1904, p. 191, and Davies, Journ. S. A. Orn. Union, 

 vol. iii. 1907, p. 1^0), recorded in both cases under the 

 name of " viridis," I am unable to place, as I have no 

 specimens available from that locality, but I should not be 

 surprised to find that it turns out to be /. e. marwitzi. 



Irrisor erythrorhynchus RUWENZORiE, subsp. nov. 



The one specimen before me from Ruwenzoii differs very 

 markedly from any Irrisor found in East Africa, and 

 certainly cannot be placed under either /. e. marwitzi or I. e. 

 niloticus. In the Trans. Zool. Soc. vol. xix. 1910, p. 432, 

 Mr. Ogilvie-Grant has recorded this specimen under the 

 name ot /. viridis Licht.,but as I have shown that "viridis" 

 is a synonym of" erythrorhynchus" and that erythrorhynchus 

 is confined to the Cape Colony, the Ruwenzori bird must 

 be given a new name. 



Similar to /. e. erythrorhynchus in the size of the spots 

 on the wings and tail, but having only the two outer pairs 

 of tail-feathers spotted ; length and colour of tail as 

 /. e. marwitzi', throat and top of head washed with green ; 

 mantle, breast, and underside of wings as in /. e. erythro- 

 xhynchus. Iris dark brown, bill and feet red.
