Birds of Celebes: Columbidae. 637 



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 inner toe 

 broadened at its base, but most developed in Turacoena; the T^, S"" and 9"^ 

 quills (counting from carpus outwards) are considerably scalloped on the outer 

 web; this is seen to a less extent in Macropygia and Columba albigularis, 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 Chalco})haps, a Ground-pigeon, 

 is very similarly marked.

A series of sjiecimens 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.; Ave, therefore, treat of it as a local race.
