This is a set of fourteen arrowheads. All appear to have been made from bone. One of the arrowheads has barbs along both edges, and the others have barbs along one edge only. The arrowheads all have conical tangs that would have been inserted into the ends of arrow shafts. The Smithsonian Instutiton catalgue identifies these items as tips for fish darts; however, they are similar in size and shape to arrowheads on arrows in the MacFarlane Collection.
