taxon notes

M. sphincter colli superficialis is present in Lagomorpha but absent in Rodentia (Meinertz, 1941, 1942; Ryan, 1989; Rinker, 1954). Some errouneous references of this muscle in rodents (e.g., Bezuidenhout and Evans, 2005) are due to decussating fibers of the deep sphincter, which creates a false superficial sphincter (Ryan, 1989)
