On comparing these measurements with those of C. cine- 

 rascens, it will be seen that the two species are nearly iden- 

 tical in size, but that the average length of the tail is slightly- 

 greater in C. fasciolatus . 



In their markings^ however, the two species are very dis- 

 tinct; thus, in C. fasciolatus, the white transverse bars on 

 the lower breast, abdomen, and thighs are much broader than 

 in C. cinerascens, the white edgings to the upper tail -coverts 

 much more conspicuous, and the arrangement of the trans- 

 verse bars on the upper surface of the tail entirely different, 

 the conspicuously wide white or whitish space stretching across 

 the middle of the tail in C. cinerascens being absent in C. 

 fasciolatus, in which species the tail is crossed by from four 

 to five dark bars, with intermediate paler spaces, all of which 

 are much more nearly equidistant from each other than is 

 the case with the bars across the tail in C. cinerascens. This 

 distinction may be readily perceived by comparing the figures 

 of the two species, which will be found in 'The Ibis' for 

 1860, pi. XV., and in that for 1862, pi. iii. 



In ' The Ibis 'for 1861, at p. 130, I mentioned that in 

 Circaetus fasciolatus "the anterior part of the inside of the 

 wing adjacent to the carpal joint is transversely marked with 

 brownish grey bars," alternating with white ones, instead of 

 being white as is the case in the adult of C. cinerascens . 

 This description applies to the two specimens in the Norwich 

 Museum, and also to the two in the possession of Captain 

 Shelley ; but iu Mr. Sharpens description of the type specimen 

 in the British Museum it is said that the under wing-coverts 

 are white, with '' a few markings of pale brown," from which
