Roberts' uncompleted projects are the Cretaceous crabs of the Atlantic and Gulf Coastal plains, only 20% complete, but the fossil decapod crustaceans from Eniwetok drill holes is 80% finished. Crabs and lobsters are rare fossils and, when fragmentary, make difficult problems.

Dr. R.S. Bassler, research associate, has continued study of the leperditioid ostracods, a large and difficult group. He reports near completion of this work.

Research associate Dr. C. Wythe Cooke has continued has studies of Mesozoic and Tertiary echinoids.
