Of the 1 9 vertebrae between the skull and sacrum, the six posterior bear inoveable ribs, of 

 which the last four pairs join the sternum : there is one pair of sacral ribs. The sternum is 

 rather small, compared "with that of other members of the Swallow- tribe, and presents the

Of the 1 7 vertebrae between the skull and sacrum, the five posterior bear moveable ribs, 

 the last three pairs of which unite with the sternum : there is a pair of sacral ribs. The

 boundary of the temporal depression, which is divided by a vertical ridge, and is separated 

 by a horizontal one from the base of the skull. The apex of the furculum joins that of the 

 sternum, and the apex of the pubis joins that of the ischium, leaving two foramina between 

 those bones.
