LINEATED CUCKOO. 179 



very narrow transverse lines of black, only half as 

 broad, in fact, as the bands on C. canorus ; the 

 tarsi are only feathered half way down the back, and 

 rtre not, as in canorus, clothed with feathers their 

 whole length ; but the chief, or at least the most 

 obvious, distinction between the two birds is in their 

 tails. In our Senegal bird there is almost an equal 

 mixture of black and white on the three external 

 tail-feathers on each side, while the outermost is 

 white, with a broad well defined bar near the tip, 

 and five others, more oblique and irregular, which 

 touch each other for a little space in the middle of 

 the inner web. No such bands are seen in canorus* 

 which has the outer tail-feather black tipt with 

 white, and two rows of small white spots, one on the 

 shaft, and another on the marginal edge only of the 

 inner web ; the orbits and two-thirds of the lower 

 mandible, in this, are orange-red, so also are the 

 nostrils : but these characters are not seen in ca- 

 norus. 



The young of this species differs so materially in 

 its plumage from the male, as to require a separate} 

 description. The size is rather less : the ground- 

 colour of the upper plumage is something the same, 

 but crossed all over with narrow and generally in- 

 terrupted bands of whitish, more or less tinged with 

 ferruginous or fawn colour ; these bands are broken 

 into spots on the greater wing-covers, where they 

 form about four series on the edge of the external 

 web ; while others, still smaller, are in the same 

 situation on the quill-feathers. On the under plu-
