Eutolmaetus spilogaster P. L. Sclater, Bull. B.O.C. xv. 

 1905, p. Q7. 



Dr. Sclater exhibited and made some remarks on a Hawk- 

 Eagle collected by Dr. Stoebr on the Zambezi, sent to him 

 for identification by the South African Museum, Cape Town. 

 He identified this specimen as E. spilogaster. This specimen 

 is now mounted in the South African Museum, and is the 

 original of my figure. 



Lophotriorchis lucani Neumann, Bull. B. O. C. xvi. 190G, 

 p. 112. 



Professor Neumann exhibited a specimen from the late 

 Freiherr C. von Erlanger's collection and stated that this 

 was the first adult of this species he had seen, as he 

 considered that the so-called adult specimen described by 

 Sliarpe was nothing but a male of N. spilogaster. 



After pointing out Erlanger's mistake mentioned above, 

 he went on to describe the following characters by which the 

 two species might be separated. The colour of the under 

 wing-coverts showed a large black patch in spilogaster, 

 while those of lucani were white with numerous black spots. 

 There was also an obsolete white shoulder-patch in lucani 

 just as in H. pennatus, and it had been suggested by Klein- 

 schmidt that lucani might be the African representative of 

 H. pennatus. L. lucani was now known from Landana, 

 Togoland, INIozambique, and South Somaliland. 



Hieraaetus lucatii Zedlitz, J. f. O. 1910, p, 374. 



Here Zedlitz quotes Neumann's remarks above, and gives 

 details of some specimens of this species which he had 

 examined. 



Lophotriorchis lucani Claude Grant, Ibis, 1915, p. 245.

 Uganda as follows: — ''Length in flesh 21 j inches, wing 

 395 mm. In clean, apparently first dress, having light tips 

 to the feathers of the head, back, wings, and rump. Irides 

 yellowish brown, cere greenish, bill blue, tip black, feet pale
