Two of the following collections (132, 135) contain fossils recognizable as corals. These are given USGS numbers and representative specimens are being placed in the reference collection. Two collections (134.1.1, 134.1.2) contain unidentifiable mollusks, and two more (126.2, 133) are so completely recrystallized that no recognizable fossils were found. A few slabs of the mollusks are being kept for the record but most of these collections and all of the last 2 are being discarded. Parts of 134 will be checked for conodonts.
