nib of that of Turacoena being more rounded; both have a large space of naked 
periocular skin, smaller in Macropygia\ all three have the sole of^^the pinner toe 
broadened at its base, but most developed in Turacoena-, the 7 , 8 and 9 
quills (counting from carpus outwards) are considerably scalloped on the outer 
weh; this is seen to a less extent in Macropygia and Columba albigulans, and 
other Pigeons. The correct position of Turacoena is somewhat doubtful, but it 
appears to be a transition -form from Macropygia to Columba, standing somewhat 
nearer to the latter. 
GENUS MACROPYGIA Sw. 
These Pigeons are smaller than a Rock-dove, and the tail, being longer 
than the wing and strongly graduated, with the outermost feather less than half 
the length of the longest, easily distinguishes them from other Columbidae in 
Celebes. The plumage of many species of the genus is barred below, and, with 
the graduated tail, gives remarkably Cuckoo-like appearance. It is probably 
a low type of Columbine plumage, as the young of Chalcophaps, a Ground-pigeon, 
is very similarly marked.

A series of specimens from the islands between Great Sangi and Celebes 
has convinced us that it is quite impossible to uphold the specific distinctness of 
M. sangirensis Salvad.; we, therefore, treat of it as a local race.
