114 THE SALAMANDER 



for Menopoma, namely, 'superficialis', 'medius', and 'profundus', 



but the 'medius' layer is indistinguishable in Salamandra. 



Innervation : From the NN. dorsalis pedis intermedius and fibu- 

 laris. 



Function: To extend the digits.

The superficial and deep strata of the extensor muscle on the post- 

 axial side of the limb are not so easily separable as on the tibial side. 

 They arise together from the epicond. lat. fern, immediately poster- 

 ior to the M. ext. dig. comm. as well as from an aponeurosis on the 

 post-axial border of this muscle. The superficial fibres — represent- 

 ing the muscle designated by the first name in the synonyms of 

 Ribbing, Rymer Jones, Hoffmann, Perrin, and Eisler — are inserted 

 on the fibularcy while the deeper fibres are inserted all along the 

 lateral face of t\\Q fibula. 



Innervation: From N. peroneus. 



Function : Extensor and abductor of the fibula and post-axial side 

 of the limb. 



4. Flexor Muscles of the Leg and Foot (PL VIII, figs. 48 and 49). 



These should be dissected from the ventral side.
