Dorso-ejiitrocJilearis (Latissimo-olecranalis). — This m iiscle tends 

 to vary from the typical maminaliau arraugemeiit in shifting its 

 origin from the latissimus clorsi to the axillary border of the 

 scapula or the surface of the infraspinatus ; its insertion, however, 

 is into tlie inner side of the olecranon as usual.

In the Suidse, Lesbres (V.) says the muscle is very well developed, 

 but in our specimen of the Eed-Eiver Hog (11) it was small. Its 

 origin is from the axillary border of the scapula close to the origin 

 of the triceps and from the fascia over the infraspinatus (11, 13), 

 but in Macalister's specimen (8) it was also connected M'ith the 

 latissimus dorsi. In the Babirusa (12) it is small and attached to 

 the latissimus dorsi. 



In the Chevrotain (20) it rose from the infraspinatus, but 

 in the Water-Chevrotain (23) from the latissimus dorsi. In
