The tail, in most species very short, has in others the middle feathers much elongated, and in one of the outer rectrices are attenuated and produced into threads.
Again, a slight deviation from the ordinary formation of the tail, whose rectrices normally number 14, and present a rounded termination, has led to the belief in a species, S.
Wilsoni, so like the English Snipe as not to be easily distinguished except by the possession of 16 rectrices, and Australia has G.
Stenura, in which the number of rectrices is still greater, varying from 20 to 28, it is said, though 22 seems to be the usual number.
The remiges and rectrices indicate perfect feathers, with shaft and complete vanes which were so neatly finished that they must have possessed typical radii and hooklets.
