very much resembles C. asiaticus, but can easily be distinguished by 

 the larger size of the white spots on the primaries, the white chin, 

 and the more subdued colour of the scapulars.

Adult male. In general coloration very similar to the larger 

 C. cegyptius, from which it differs at a glance by the colour of the 

 primaries. The colour of the upper parts is exactly like that of 

 the ordinary dark specimens of C. (egyptius, and that of the under 

 surface docs not differ perceptibly. The wing is much shorter ; 

 the first three primaries deep brown, rufous isabelline near the base, 

 and with large white spots in the middle of the feather ; on the 

 first primary the white spot is clearly defined on the inner web and 

 a part of the shaft only, but always reaches the shaft ; on the 

 second and third it is spread over both webs ; the other quills are 

 deep brown, bordered and spotted with rufous-buff; the two outer- 

 most rectrices are white for at least one third of their length, these 

 white spots more or less distinctly bordered with pale isabelline. 

 Total length about 9-5 inches, wing 6-8, tail 4-1 ; tarsus not 

 feathered in front exct-pt on the uppermost part, 0*7 inch in length. 



Adult female. Similar to the male, but having the two outermost 

 rectrices unhanded for about half an inch only, and pale sandy 

 isabelline instead of white : the white spots on the primaries 

 generally less pure. 



Young. Young individuals are paler, the dark markings and the 

 white spots on the throat less pure, the abdomen indistinctly 

 banded. Young males have the white spots on the tail and 

 primaries well developed, and differ from young females in the same 

 way as the adult.
