ICTINAETUS. 347 



The generic name Neopus, used generally for this Eagle, was 

 published in 1844 (Gray's Zool. Misc. p. 81), whilst Jerdon's name 

 Ictinaetus dates from a year earlier, having been published by 

 Blyth (J. A. S. B. xii, p. 128) in a note to the paper in which 

 Hodgson gave the name Heteropus, which had to be discarded on 

 account of previous use (Ibis, 1894, p. 289).
