This muscle corresponds with the combined obliquo.* inter nit ft and 

 (ransveni'*, and has therefore been described either as the one or the 

 other, by various authors. 



The fibres arise tendiuoiisly 



a. From the transverse processes of the vertebrae from the 

 fourth backwards, and from the fascia covering the mm. interfrans- 

 rermrii. 



b. From the iliac bone, by a strong tendon from its upper border, 

 and by a few weaker fibres from its outer surface. The latter fibres 

 are covered by the former, and these end posteriorly in a sharp 

 concave border. 



The muscular bundles diverge from these points, some running 

 forwards, some backwards ; the former are only partially covered 

 by the portio omo-abdomiitali* of the m. oLliquiis externus (compare
