'The European synonymy of .\fu»lelus musletus and Cynias canis is In a state of great confusion, as 

 few of the earlier writers recoRnizefl any (iifference between the two species externally very much alike. 



'The genus Galeus of Rafinesque was based on species with spiracles, dilTering from Squalus by the 

 presence of an anal fln. One new species is described, Oaleus melaslomus, later type of Bonaparte's genus 

 PTistiunu: but on the same page and the next. page Ilafinesque speaks of other species— Galeus vulpecula, 

 G. calulus, and G. mustelus. It is plain that Squalus galeus h. was his intended type, after the general 

 custom of writers who elevated species to the rank of genus; but he does not mention that species in the 

 paper nor in his Indice, and as Squalus gateut was therefore not available as type, Jordan and Gilbert 

 selected Squalus mustelus for that purpose, thus making Galeus Kaflnesque a synonym of Mustelus Leach, 

 rather than to displace Pristiurus. Apparently this procedure was allowable, unless some earlier author 

 had chosen either Pristiurus melastomas o iScglliorhinus calulus {canicula) tor that purpose.
