postscapula, and its edge is the posterior border (gb) ; a third 

 projects outwards, constituting the mesoscapula of Parker, 

 called more commonly the spine (s). The first-named border 

 (cb) terminates below by joining the coracoid, and hence, to 

 avoid the inconvenience of a term which is only expressive 

 when the bone is in a particular position, it may be called 

 coracoid border; the second (gb) joins the prominent margin 

 of the glenoid fossa, and may, for the same reason, be called

 less prolonged into a curved, flattened process, called the 

 acromion (a). 



The flat or concave surfaces or fossae between these pro- 

 jecting lamellae are — (1) the prescapular or anterior fossa 

 (af), between the coracoid border and the spine, called, in 

 works on human anatomy, "supraspinous fossa;" (2) the
