292 THE MYOLOGY OF THE RAVEN. 



They do not occur in the dorsal region of the back, 

 for in this locality their places are usurped by stout 

 and tough ligaments which are quite inelastic. These 

 ligaments are much smaller and cord-like as they extend 

 between the low neural spines in the mid-cervical region. 

 Now it is only between the lofty neural spines of the 

 leading cervical vertebrae, commencing with the second 

 and third to include the fifth and fourth, and between 

 the last few cervicals that we see the true interspinales ; 

 for passing the thirteenth cervical in ascending the 

 column, we find that these muscles gradually become 

 bilateral, and in the mid-region of the neck, stretch 

 between two vertebrae, and finally become continuous 

 with the anterior descending fasciculi of the longus 

 colli posticus. 



136. The interarticulares represent another deep- 

 seated series of intervertebral muscles. Examining them 

 upon either side, we find that they start as a w T ell-deve- 

 loped muscle extending between the postzygapophysis 

 of the axis to the hinder margin of the ring of the 

 atlas. Then in general throughout the vertebral column,

they occur as muscular bands extending from the 

 postzygapophysis of one vertebra to the same processes 

 of the vertebra next beyond. In old and muscular 

 subjects, however, we often see, between the fifth

 I question whether his obliquus colli represents the mm. intertrans-
