MR. F. E. BEDDARD ON THE 



[Nov. 1 8, 



femur just ventral to the insertion of the sartorius from the fascia 

 covering the fore part of knee and for some distance helow from the 

 cnemial crest of the tibia, and from the fascia between it and the 

 tibialis anticus near the upper end of the latter. 



Muscles of leg of Scopus umbretta. 



a, Adductor; st, semitendinosus; Ast, accessory semitendinosus ; sm, semi- 

 membranosus ; g, g 2 , g 3 , g i 1 gastrocnemius. 



The arrangement of the gastrocnemius and the adjacent muscles 

 will be understood from the accompanying figures (fig. 3). 



1/. The plantaris is a small slender muscle ; it arises from the 

 hinder part of tibia on inside of the leg posterior to the insertion of 

 the semimembranosus. 



18-19. The superficial flexor tendons are like those of other 

 birds ; the flexor perforatus et perforans supplying the 2nd and 

 3rd digits, while the flexor perforatus supplies the 2nd, 3rd, and 

 4th. 



The deep tendons (see fig. 4) have rather a peculiar arrangement. 



20-21. The tendon of the flexor hallucis is connected with the 

 flexor profundus by a vinculum just before the latter divides into 

 the tendons of the several digits ; it also gives off a special slip, 

 which joins the branch of the flexor profundus going to the 2nd 

 digit. 



22. There is but one peroneus present ; it arises chiefly from the 

 fascia covering the tibialis anticus and from the crest of the tibia ; its
