These present the same general arrangement as in the horse. The
=sacro-coccygei=, however, arise on the lumbar vertebræ also, and the
=coccygeus= on the ischiatic spine. There is found a =sacro-coccygeus
accessorius=, which arises on the internal border of the ilium, the edge
of the sacrum, and the transverse processes of the first coccygeal
vertebræ, and is inserted between the superior and lateral
sacro-coccygei. It is homologous with the intertransversales.
