for some of its fibres, instead of ending; in the patagial tendons, are 

 inserted on to the deltoid crest. The patagialis brevis tendon 

 {tig. 2) is somewhat wide and diffuse ; it gives off a wristward 

 slip near to its insertion on the forearm, from which arises 

 a patagial fan joining the tensor longus tendon. The Biceps 

 slip has already been referred to ; it joins the tensor longus tendon.

The Anconaius, as in other Steganopodes, has besides its scapular 

 origin a tendinous connection with the scapula and with the 

 humerus. 



I could not fiud an Expansor secundariorum. 



The Latissimus dorsi anterior is less than half the size of the 

 posterior. The most posterior portion of thelatter arises as a special 

 slip below (covered by) the sartorius. Tlie tendon of insertion of 

 the posterior division is, as usual, inserted on to the humerus in 

 common vnt\i the humeral attachment of Anconseus. 



There appears to be no Lat. dorsi metapatagialis. 



The two Bhomhoidei are about equisized. The profundus springs 

 aponeurotically. 



The Serratus superficialis is as usual made up of an anterior and 

 posterior portion. The anterior portion is composed of two slips 

 arising respectively from the last cervical and the first dorsal rib ; its 

 tendon of insertion is connected with the suhscapidaris extemus. The 

 posterior division arises tendinously from dorsal ribs 2, 3, and 4. 



The Serratus jirofundus arises from the last cervical and the first 

 two dorsal ribs ; the several slips decrease in size from before 

 backwards. 



The Serratus metapatagialis is a large muscle arising from the 

 four ribs in front of the last.
