Abstract
Brown County, Nebraska, which has been so prolific of long-jawed mastodons, has yielded another form which seems to be new and which may throw light on certain small tusks that occur where Tetrabelodon bones abound. Heretofore, we have considered these to be embryonic, but they show apparent wear, and in other respects they are enigmatic, and at best, atypical. Tetrabelodon tusks proper, however young, are typical, and are obviously tusks in miniature. The tusks in doubt are of varying lengths and about the diameter of one's thumb, but taper backwards, are worn to a bluntly oblique point, and are slightly fluted. Can it be that these are vestigeal, lateral incisors of the mandible, I 2?
