at about the middle of tlie lower tliird of the shaft of 

 the ti1.)ia. It passes in front of the external malleolus, 

 crosses the ankle joint, and is finally inserted into the 

 outer edo-e of the summit of the tarso-metatarsal bone. 



This appears to be one of the peronei muscles of 

 A. Milne -Edwards ; but from the facts that it is evidently 

 inserted into the tarsus, and not the metatarsus ; and 

 that the tibialis postimis is quite a constant muscle 

 among Reptiles ; and that further, as I have already 

 said, the peronei muscles are more particularly mam- 

 malian institutions, I believe w^e are safer in calling this 

 one the name we liave.^ 



1 The only muscle I can find in literature to compare the pre- 

 sent one with is the Feroneus profundus of Gadow, who offers the 

 following upon it (loc. cit., p. 182) : —
