Raptorial Birds of the Malay Archipelago. 17 



Wing 15*75 in. Iris dusky olive; bill black; cere, gape, 

 and feet yellow. 



Elanus, Savigny. 

 Elanus hypoleucus, Gould, P. Z. S. 1859, p. 127 ; E. in- 



termedius, Schleg., Mus. P.-B. Milvi, p. 7. 



Hab. Macassar (ffa//.) ; North Celebes, Borneo, Java (3fws. 

 Lugd.). 



Bill black ; cere and feet yellow ; iris red. 



I cannot think that Elanus intermedius is distinct from this 

 species, since the spots on the under wing-coverts (which is almost 

 the only point of difference) occur in the immature birds. 



Pernis, Cuvier. 



Pernis cristatus, Cuv. ; Schleg,, Mus. P.-B. Pei-nes, p. 2, 

 Valkv. Nederl. Ind. pi. xxv. fig. 1-3, pi. xxvi. fig. 1, 2 ; Faico 

 ptilorhynchus, Temm., Pi. Col. 44. 



Hah. Sumatra^ Bangka, Java [Mus. Lugd.) ; India {Jerdon). 



Var. celebensis, Schleg., Valkv. Nederl. Ind. pi. xxvi. f. 3. 



Hab. Celebes {Mus. Lugd.). 



The variety from Celebes figured by Prof. Schlegel is coloured 

 exactly like Spizaetus lanceolatus, which is also peculiar to that 

 island — a most remarkable fact, which indicates either the action 

 of some local peculiarity in determining specialities of colour, or 

 the existence of ^'mimicry" between these birds. I am sorry 

 Prof. Schlegel has not conferred a specific name on it, since he 

 has done so on local forms less distinctly marked — for instance, 

 Baza rufa and Spilornis sulaensis. 



Henicopernis, G. R. Gray. 

 Henicopernis longicauda (Garnot, Voy. Coquille, i. p. 588, 

 pi. 10) ; Dcedahon longicauda, Lesson, Tr. d'Orn. i. p. Q7 ; Pernis 

 {Henicopernis) longicauda, G. R. Gray, P. Z. S. 1859, p. 153; 

 Schleg., N. T. D. iii. p. 327. 



"Rostro pedibusque luteis, corpore supra nigro brunneaceoque, 

 subtus fulvo-alba longitrorsum flammis nigris, cauda fasciis 

 nigris et albidis intersecta.^' {Lesson.) 



Hab. New Guinea, Mysol, Waigiou {IVall.); Aru Is. {Mus. 

 Lugd.) .
