Observations. Rafinesque's descriptions do nof ` re E: 
Ply to this rare species, but I believe it is the one for which 
they were intended, I therefore retain his name. The form 
And color distinguish it from the other members of this family. 
It is not esteemed for food even as highly as many of them.
