These are taxonomically similar to KarkJins' (1984) Tarpho- phragma miiltitabiilata zone. In fact. Brown noted Tarphophragma midtitabidata. Prasopora falesi, and Eridotrypa mutabilis, three of the more common fau- na] elements described in the present report, to be some of the most abundant and well-characterized fau- nal components of his study area.
