 THisiljighly singular  species  of  Pigeon is an inhabitant of  the most rugged,  rocky anch sterile  districts  of  
 the. north-west  coast  of Australia.  The  specimens  in  my possession were sent ^e^h^the' Officers  of the  
 Beagle,  hut, I  rfegret to say, were unaccompanied by any particulars respecting their  history.  The form of  
 the wm^^onMr lead us tp^imagine  that in many parts  of its  economy this species much resembles those of  
 the members of  the genus >Geophaps;  but on  these points nothing  can  be  ascertained with certainty, until  
 the  productions' of  those remote parts  of Australia have been  carefully investigated,  a period which, from  
 the inhospitable character of.the country, I  fear isfaifdistant. 
 Crown of the head and neck greyish brown, margined with  sandy brown;  all the upper surface, chest and  
 tail rufous brown,  the cemgMof each feather imftn^^tiMMey;;  loreslblabk ;abdomen and"under tail-coverts
