This report is on 19 collections from the Livengood area; they have since been considerably augmented by a large number of collections made by F. R. Weber in 1962. (see report to Weber, shipment A-63-11).

Pelecypod specimens from this original material were used by McAlester in 1962 for description of a new species of Actinopteria. A. taberi was thought by McAlester to be intermediate in form between two New York species that occurs in the Middle Devonian and Chemung age strata.

We would appreciate having accurate stratigraphic and geographic locality data for these collections so that they can be adequately catalogued.
