This is a revised report on two collections from Shipment A-60-20 by W. B. N. Berry, undertaken at my request. It provides a more accurate analysis than my original report on the fauna. - Reuben J. Ross, Jr.

The specimens are better-preserved than those collected by Ross, Brabb, and Churkin from the same localities in the summer of 1962. Many specimens are well preserved.
