THE MUSCULATURE OF THE TRUNK. 289 



133. The rectus cap it-is lateralis is a well-deve- 

 loped muscle in the present subject. It arises some- 

 what tendinous from the diapophyses of the fifth, fourth, 

 and third cervical vertebrae ; and, passing obliquely 

 upwards in front of the spinal column, the fibres con- 

 verge to form a strong, sub-compressed tendon, which 

 is inserted into the inner tubercle on the basal ridge 

 of the basitemporal. 



134. The trachelo-mastoideus 1 is a powerfully deve- 



Longus colli. Owen, Apteryx, p. 310.

1 No little confusion seems to exist in recognizing and dis- 

 tinguishing these remaining two cervical muscles, i.e. the rectus 

 capitis lateralis and the present one, the trachelo-mastoideus. For 

 my own part, I can show them no clearer, at present, than I have 

 attempted to do in Fig. 70 of this work. Even Gadow seems to 

 have seen the two muscles in his one that he has called the 

 " longus lateralis cervicis et capitis," and of which he gives the 

 following account (loc. cit., pp. 116, 117) :
