a The identifications of the species were either made or checked by Dr. 

 Albert Mann of the U. S. Department of Agriculture who is an authority on 

 these organisms. 



1. Amphora ovalis. — Several specimens showing considerable variation 



found. 



2. Cymbella gastroides Kutzung. — One valve only. 



3. Navicula (Stauroneis) phoenicenteron. — One valve only, which differs 



slightly from living examples of the region. 



4. Navicula peregrina Ehrenberg. — Two valves only. 



5. Navicula rhynchocephala Kutzung. — One specimen. 



6. Navicula, new species. — One broken valve of an undescribed Navicula 



was mounted. 



7. Chetoceros cinctum Gran. — Several specimens found. 



8. Thalassiothrix nitzschoides Grunow. — Exceedingly abundant and vari- 



able in size and shape. 



9. Melosira sulcata Ehrenberg. — Several varieties of this excessively vari- 



able species were found in the deposits. 



10. Baphoneis amphiceros Ehrenberg, variety. — The beading of specimens 



found is exceedingly coarse; center rows have only 4 beads. 



11. Actinoptychus splendens Ealfs. — One specimen. 



12. Actinoptychus undulatus Ehrenberg. — Two specimens. 



13. Actinoptychus, new species. — An undescribed form of this genus was 



found to be abundant and somewhat variable. It is especially 

 characterized by the large size of the beads.
