LiCfUE follows Westling in her ilescription of the first part, but 

 iu the tlescription of the posterior portion he says, " von dea 

 Ruckenwirbeln wird der 11-12 Rippe." 



MiVART says — " This muscle, as in the Ornithorhynchus [quoting 

 Meckel and Owen], consists of two parts. The posterior part is 

 triangular and arises from the last eleven dorsal, and the first 

 lumbar, vertebrae." The anterior part, he says, is inserted into the 

 whole length of the spine and acromion, and also into the more 

 anterior part of the vertebral margin of the scapula, and into the 

 outermost end of the clavicle. 



Ornithorhynchus. 



Owen — " The trapezius is divided into two muscles ; the pos- 

 terior portion is an oblong slender triangle arising by a bread 

 tendon from the tenth and eleventh vertebrae and ribs ; and inserted 

 by a short strong tendon behind the extremity of the spine of the 

 scapula; the anterior portion arises from the occiput and tendinous 

 raphe connecting it with its fellow of the opposite side, and is 

 inserted into the spine of the scapula and into the outer half of 

 the clavicle." 



CoUES describes the anterior and posterior part of the muscle. 

 "The latter part," he says, "arises from the 10th and 11th ribs 

 by two fleshy digitations situate respectively 1' and Ih' from 

 the back-bone ; and from a broad, oval dorsal aponeurosis com- 

 mon to it and its fellow." 



Leche follows Meckel, and says that the anterior part arises 

 from the occiput and ligamentum nuchse, and that the hinder part 

 arises from the 10th and 11th spinal processes and corresponding 

 ribs. 



Meckel — " Cucullaris in duos, ni graviter fallor, dividitur 

 musculos. Alter, inferior, triangulum refei't valde oblongum 

 atque teuuem, vertebra dorsali et costa decima et undecima, tendine 

 lato oritur, dimidio inferiore latissimum tegens, sursum tendit 

 atque tendine brevi, forti scapulae inseritur marginis superioris 

 fini antico." He then goes on to describe the anterior portion.
