The clavicle is a slender bone, bent so as to form about a quadrant of a circle, with an unornamented upper end of nearly circular section, but bearing a groove on its posterior surface which receives the lower end of the cleithrum. The lower end of the clavicle is ¿attened and expanded antero-posteriorly so that it forms a relatively broad plate of bone which overlies the recessed antero-lateral part of the ventral surface of the interclavicle, and like that bone has its outer face covered with a pitted ornament.The cleithrum is a very large bone forming a cap over the dorsal end of the scapula, and provided with a long slender process applied to the front edge of that bone and itself covered below by the upper end of the clavicle.The humerus is a short, very massive bone with an exceedingly short shaft and much-expanded ends, whose broad surfaces make a considerable angle (about with each other.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
