is difficult to kill, as it generally escapes from the 

 opposite of the bushes, in which it takes refuge when 

 pursued, or apprehensive of danger. 



In length it measures nearly eleven inches. The 

 forehead, the cheeks, and the throat are white. The 

 crown, the neck, and the whole of the under plu-

 feet reddish-brown. 



The subjects of the four remaining Plates differ in 

 many respects from all we have yet been engaged 

 with, but whether they will form a separate division 

 or the three first will enter among the Peristerinae, 

 and the Lophyrus alone remain the representative of 

 another group, we are unable to determine, not pos- 

 sessing sufficient materials to institute so strict an 

 analysis as is necessary, or to trace out with preci- 

 sion the direct affinities of these species, and the si- 

 tuation they hold in respect to the other groups of 

 the Columbidse, as well as those of adjoining fa- 

 milies. The three first we have provisionally in- 

 cluded in the
