THE MUSCLES OF THE UPPER EXTREMITY. 93 



three strong digitations, each of considerable bulk. 

 The first of these slips arises from the outer aspect 

 of the second true dorsal rib (counting from before 

 backwards) rather above the base of its epipleural 

 appendage. The other two slips arise from similar 

 points on the next two succeeding ribs, just above 

 the origin of the dermo-ulnaris. The extremities of 

 these digitations of the serratus magnus anticus, are 

 strongly inclined to partake of a tendinous character, 

 and the first two may be more or less attached to the 

 interpleurapophysial membrane. They converge as

If the reader will refer to my dermo-ulnaris (No. 11 of the 

 present work) he will find that that muscle represents the pars 

 metapatagialis of the above synonymy ; so that the synonyms here 

 will probably stand thus
