Page 38, line 6. No described Ephemera is contained 
in Stettin amber. Amber is either not found at all at 
Stettin or only rarely. All the amber insects are from 
Eastern Prussia, from between Danzig and Konigsberg 
to Meniel. I believe that when I described the amber 
species my knoAvledge of the living forms was rather 
limited ; perhaps other conclusions respecting them Avoidd 
be arriA'ed at now. 
Page 38. 1856. — Goldenbnrg. I also believe that 
Dictijoneura does not belong to the Ephemerida. 
Page 38. 1861.— H. A. Hagen. My Solenhofen 
species are perhaps untenable. Of Ephemera cellulosa 
I have now beautiful specimens, and even of mortua some 
better ones.
