The four posterior notches of the sternum extend as far forwards as the commencement of 

 the keel. There is a callosity behind the middle of each metatarsus, where the spur is deve- 

 loped in the Cock. The mastoid joins the postfrontal. There are 20 vertebne between the 

 nkull and sacrum, of which the last six support ribs : the first two pairs are free and floating ; 

 the remainder are articulated to the sternum by hsemapophyses ; the last (seventh) pair of 

 ribs are attached to the sacrum : a single free dorsal vertebra intervenes between the four 

 coalesced dorsals and the sacrum. There are 7 caudal vertebne.

The number of vertebne between the skull and sacrum is 20, of which the last seven sup- 

 port moveable ribs : of these the first two pain terminate freely ; the rest are attached to the 

 sternum by hjemapophyses ; there is an eighth pair of ribs attached to the sacrum. Thr 

 four posterior notches of the sternum are of moderate depth, and the keel is long and deep ; 

 these modification* being in accordance with the length of the wing, and the remarkable

The vertebral formula corresponds with the preceding, except that the pleurapopbyses of 

 the fourteenth vertebra are anchylosed, and those of the two following vertebne terminate 

 freely. The hstmapophyses of the sacral ribs reach the sternum. The two median posterior 

 notches of the sternum are converted into foramina : the two lateral ones are wide and deep, 

 their outer boundaries being slender and parallel with the hstmapophyses. The keel of the
