26 STUDIES IN COMPARATIVE ANATOMY. 



becomes tendinous, and passes down into a groove behind the 

 external malleolus, external to Peronmus brevis. The muscle 

 winds round the outer edge of the foot, to be inserted deeply, 

 beneath the calcaneo-cuboid ligament, into the posterior border 

 of the cuboid. A small part of the tendon passes further into 

 the sole, towards the bases of the metatarsals.

 Mayer states (incorrectly), that peronmus longus is pierced by 

 the peroneal nerve. 



Feronceus hrevis arises from nearly the whole of the outer 

 surface of the fibula. It becomes tendinous along its anterior 

 border immediately above the external malleolus ; but the 

 muscular fibres are prolonged nearly to the insertion along the 

 posterior border. The tendon lies in the groove behind the 

 external malleolus, and is separated from that of ^jcrowosws longus 

 by a division of the external annular ligament. It then crosses 

 the base of the 5th metatarsal, and is inserted principally into 

 the fibular side of the metatarsal of the 4th digit; also, by a 

 small sHp, into the proximal phalanx of the 5th. Feronceus hrevis 

 underlies F. longus, and is much broader than that muscle. 

 The peroneal nerve passes between them.

 anticus. 



Feronceus anticus arises by a round tendon from the external 

 lateral ligament of the knee, and by a second head from the top 

 of the tibia and lower two-thirds of the front of the fibula, ad- 

 jacent to the tibia. It divides into two main slips. The more 

 superficial passes outwards, and is inserted into the outer border 

 of the 5th metatarsal. The deeper portion is subdivided into 

 two parts, of which the shorter passes to the 4th and 5th meta- 

 tarsals ; the longer to the fibular side of the 4th. A slip from 

 the anterior border of the external malleolus blends with the 

 muscle. This accessory slip would agree with F. tertius.
