supraspinous fossa. The fibers converge, the muscle becomes partly 

 tendinous, and passes over the head of the femur to insertion into 

 the craniolateral infraspinous fossa of the humerus. 



In Kogia this muscle is very similar but the insertion is shown as 

 being located slightly more caudad, and is probably weaker. In 

 Balaeiwptera the origin occupies the middle of the lateral aspect of 

 the scapula and the insertion is more proxilnad. It is not fully 

 described nor figured for Glohiocephala.

and is inserted upon the caudo-distal part of the medial shaft of the 

 humerus. 



In Kogia this muscle is apparently somewhat similar, but origin 

 extends a bit farther toward the glenoid fossa; and the insertion is 

 not shown in the illustration. In Balaenoftera the origin is much 

 more extensive, and forms a considerable area over the more caudal 

 part of the lateral aspect of the scapula. 



The subscapularis has origin from the scapular membrane near 

 its vertebral border and covers the entire medial aspect of the 

 scapula. It develops strong tendon bundles upon its superficial 

 (medial) belly, but the deeper part is entirely fleshy, and insertion is 

 obliquely upon the tuberosity of the humerus and distad, after the
