The Cathartes differ from the Vultures of the Old World in many other points besides 
those specified. The hallux is small and elevated above the level of the other toes; the 
semitendinosus and accessory semitendinosus muscles are present ; the femoro-caudal muscle 
is sometimes absent; the oil-gland is nude; the maxillo-palatines are much wider apart, and 
though the distance is bridged over by an ossified nasal septum the ossification does not 
prevent the nostrils being pierced; they have no cxca Ke. Ke. 
Garrod placed the Cathartes between the Herons and the Storks,
