July 26 1921. Tuesday Boston Mass. Finished today picking out a duplicate set of Bithemian brachipods out of the Johary Collection. I have picked out about 200 species, and Barrande has described about 600 forms. In the end I doubt if B. has as many as 500 forms. When the Johary collection is wholly labeled, there maybe 300 and not more than 350 forms. The great majority of species are in E2 and especially in F2. Then in D, next C, F1 and least in H. What I have will make a few exceptions illustrate all the genera. I can now Steptoi or Paterula.
