T. media. — These arc small feathers, calling for no special 

 description ; as in Corvus, for example, a wide space separates 

 these coverts from the : — 



T. minores. — Only one row of these coverts appears to be 

 present; as we have just remarked, these are cut off from 

 the /. media' by a broad aptcrion, and this extends back to 

 the elbow, and forwards along the humerus, being bounded 

 by the biceps tendon immediately beneath.

Parapteron. — Owing to the short humerus this is repre- 

 sented only by some six tiny semiplumous feathers wedged 

 in between they;/, humeralis and the secondaries. 



Aftershaft. — This is wanting. 



Fi/o plumes. — About three of these feathers occur at the 

 base of each contour feather; they are of considerable 

 length along the spinal tract, but do not develop a vane. 



Oil-gland. — Naked and nipple-shaped. 



Rhamphotheca. — The tomium is entire ; the nostrils open 

 at the extreme base of the beak and are concealed by 

 feathers.
