THE ANATOMY OF THE INDIAN ELEPHANT. SI 



Adductor minimi digiti. — A smaller muscle than tlie last. 

 Arises from under surface of os calcis, in front and to the inner side 

 of the ahdudor ; also from calcaneo- cuboid ligament. Inserted 

 into the sesamoid just mentioned to the inner side of the abductor. 



Not in C. and L. 



Flexor hrevis hallucis. — A small, short muscle, arising from the 

 sustentaculum of the os calcis, beneath a strong ligamentous 

 band which stretches across the centre of the tarsus. 



Not in C. and L. 



Interossei (pedis). — Only a single plantar inter osseus can be 

 distinguished. It arises from the tarsus, opposite the bases of 

 the third and fourth metatarsals, and is inserted into the fibular 

 side of the base of the second digit. The second, third, and 

 fourth digits are provided with dorsal interossei, almost exactly 

 resembling those of the manus. 



Not in C. and L. 



Muscles of the Head and Tkunk — Facial Muscles. 



Occipito-frontalis. — A double-bellied muscle, with intermediate 

 tendon. The posterior belly, the larger of the two, arises from 

 the cranial aponeurosis along a line connecting the two auditory 

 apertures. The anterior belly arises from the supra-orbital 

 region, partly blending with the orhicukcris palpebrarum. 

 C. and L. — 274-5 (la), anterior beUy — " surciliers." 

 Platysma myoides (facial portion of Panniculus). — This muscle, 

 passing over the angle of the jaw, is inserted as follows : — A few 

 of the lower fibres pass to the outer surface of the horizontal 

 ramus of the mandible, a little in front of the facial artery, 

 where it crosses the bone ; the uppermost fibres to the facial 

 aponeurosis below the zygoma ; the intermediate and principal 

 portion of the muscle converges to the angle of the mouth, 

 where its fibres interlace with those of orbicularis oris and 

 levator anguli oris. 



C. and L.— 272-3 (2, 4), " facien "— " thoraco-f acien." 

 Cutaneous muscle of the occiput. — This is described by Dr Wat- 

 son as arising from the cranial aponeurosis of the posterior sur- 

 face of the skull. The fibres pass transversely outwards to be 

 inserted into the cranial aponeurosis immediately behind the
