UNTIL the various modifications of form in this mont 

 extensive family have been more regularly and 

 completely studied, we shall arrange all tne slender 

 billed pigeons with naked legs under two provisional 

 genera, which we suspect to be the typical and the 

 subtypical. To the first we restrict the name of 

 Columba; they are distinguished by their lateral toes 

 being equal or of the same length ; under this will 

 come the sub-genera of Columla proper and Ecto- 

 plstes. The second group, probably the sub-typical, 

 is Turtur^ wherein the outer toe is shorter than 

 the inner, and to which the two next birds herein 

 described obviously belong, as probably does Chce- 

 mipelia. 



Size of the common turtle. General colour of 

 the back, interscapulars, wings, and tail, grey-brown ; 

 having a strong cinereous tinge on the back, and a 

 slighter one on the rump and outermost wing-covers;
