Relations. — It is concealed by the alar aponeurosis and rests against the bones of the 

 forearm.

Attcichments. — This muscle is entirely represented by tendon. It arises from the 

 inner side of the lower end of the humerus, close to the posterior border of that bone, 

 and behind the internal humero-ulnar ligament. It passes along the inner side of the 

 forearm, and immediately above the wrist joint divides into two slips. Of these one 

 (petit palmaire of Gervais) is inserted into the inner side of the ulnar carpal bone, while 

 the other (flechisseur de la premiere phalange of Gervais) passes onwards, to be inserted 

 into the inner side of the base of the first radial phalanx. 



Relations. — It is concealed by the alar aponeurosis, and rests against the inner side of 

 the ulna. 



Variations. — In Aptenodytes longirostns the second portion of this tendon unites 

 with that of the preceding muscle, and both are inserted into the base of the terminal 

 radial phalanx. A similar arrangement was met with in a specimen of Eudyptes chryso- 

 come from Kerguelen. 



Remarks. — According to Schoepss, this tendon in the Penguin is inserted into the 

 terminal radial phalanx. He does not describe its insertion into the ulnar carpal bone. 

 Meckel found the flexor sublimis and flexor jirofundus in the Penguins represented by 

 a single tendon. This is not the case in any specimen which I have examined. 



5. Flexor minimi digiti.
