This muscle corresponds with the combined obliqn/is internns and Iransversus, and has therefore been described either as the one or the other, by various authors. The fibres arise tendinously— a. From the transverse processes of the vertebrae from the fourth backwards, and from the fascia covering the mm. mtertrans- versarii. 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 port'io omo-afjdoininalis of the in. oljltquus externus (compare.
