cellular substance, also a bursa mucosa. These ligaments are 

 bounded in front by the subclavius, and behind by the trapezius 

 muscle. 



The Bifid Ligament (Lig amentum Bicorne) is placed in front 

 of the subclavius muscle. It arises from the root of the cora- 

 coid process, at the sternal side of the conoid ligament; and 

 proceeding with but little elevation, inwards and upwards, in- 

 creases in breadth and bifurcates. The superior horn is in- 

 serted along the under margin of the clavicle, to near the rhom- 

 boid or costo-clavicular ligament; but the lower one goes to 

 the end of the first rib, under the tendon of the subclavius mus- 

 cle. This ligament is a sort of fascia placed over the subclavius 

 muscle, to bind and strengthen it.* Some of the fibres of the su- 

 perior horn sometimes proceed farther, and leaving the clavicle, 

 go with the rhomboid ligament into the cartilage of the first 

 rib.t 



The Coracoid Ligament (Lig. Coracoideum) stretches across 

 the notch on the superior costa of the scapula, and converts it 

 into a foramen. It runs from the posterior margin of the notch 

 to the base of the coracoid process, and has some of its fibres 

 blending with the conoid ligament. It consists of a small fasci- 

 culus of fibres, and is of very little consequence, excepting in its 

 relation to the superior scapular vessels and nerves. 



The Triangular Ligament (Coraco-Acromialis) of the Scapula, 

 as its name implies, extends from the coracoid to the acromion 

 process above the shoulder joint. It arises from nearly the 

 whole superior margin of the coracoid process, in two divisions, 

 separated partially by cellular tissue. Its fibres converge in 

 their progress, by which it becomes thicker, and is inserted into 

 the point of the acromion process, just beneath its junction 

 with the clavicle. This ligament is covered by the deltoid mus- 

 cle and the clavicle, and has the supra-spinatus beneath it. Its 

 anterior margin is continuous with a condensed cellular mem- 

 brane beneath the deltoid.
