There is fome doubt whether Mr. Hudfon really knew this grafs, 
or whether what he took for B. arvenfis of Linnzus is merely a 
variety, as he made it, of his B. ereéfus; and this point can never be 
determined. The two fpecies have lefs refemblance or affinity 
than moft other Bromi, and could furely never be confounded.
