distant from each other," but as his figure resembles somewhat the 
No. 3 of my plate, drawn from Mr. Longe's specimen, I cannot help

rare. 
There is another species of Berenicea described as Berenicea 
minnesotensis, Ulrich, which the author says is almost exactly inter- 
mediate between the Cincinnati group, species B. primitiva, and B. 
vessiculosa," but no figures are given.
