Sacalius: ‘The precise name of the animals of this group [the jackals] having 
thus escaped distinct notice among the ancients, the modern Greeks adopted 
those of Squilatehi and Sakalia, one of which, being an oriental adaptation, 
proves the absence of a national and ancient name; and for the same reason 
we apply it to the present form of minor gregarious canines." (H. SwrrH, 1839.)
