This report supplements those of W.A. Oliver, Jr. (dated 8/18/59) and Serge Mamay (dated 6/1/59). Additional brachiopods and molluscs in collections 58(?)AMr387 permit a refinement of the age designation of that collection. It is either of latest Middle Devonian or earliest Late Devonian age. Collection 58AL88 contains linguloid brachiopods, perhaps assignable to the genus Barroisella, that suggest a Middle or Late Devonian age. E&R report prepared by J.T. Dutro, Jr., in consultation with E.L. Yochelson |

The following is a report on the corals in the submitted collections. Brachiopods, which may provide additional age date will be separately reported on at a later date. Age determinations may be summarized as follows: Coll. 33 & 53AMr387 [note by R.B. Blodgett, this should be 58AMr387] - Silurian or Devonian Coll. 58APy183 - Post-Devonian Paleozoic; will be reported on by Helen Duncan Coll. 58ACo271 - Silurian Coll. 58ACo272 - Silurian, Lower Devonian or Middle Devonian Coll. 58ACo274 - Silurian, probably Lower or Middle Silurian Coll. 58ACo291 - Silurian |

Comment: | Heliolites ranges from the Lower Silurian to the Middle Devonian and the age of the collection must fall within this range. The Favosites is different from those in the other collections and is of little use here for age determination. |
