Turtur erythrophrys , Swains.

serai-collar ; orbits red. 
Until the various modifications of form in this most 
extensive family have been more regularly and 
completely studied, we shall arrange all the slender 
hilled 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 Columba proper and Ecto- 
pistes. 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;
