Kansas University quarterly . PLATK XXV. Tetracaulodon Shepardii, Figure: Maxillaries with first two molars; jPhillips county,Kansas. Lower Figures: Last upper molars; Phillips county, Kansas. Kan Univ. Vol. VIII. No. :., Series A. ILATE On Tetracaulodon (Tetrabeloclon) Shepardii, Cope. BY GEORGE WAGNER. With Plates XXIV, XXV. In the paleontological museum of the Universit} of Kansas is themandible of a mastodon, from the Loup Fork beds of Phillipscounty, Kansas. It consists of a nearly complete left ramus, withthe last molar in place. (See Plate XXIV). The jaw agrees so com-pletely with Tetrabelodo7i sJicpardii, described by Cope*, that it mustbe considered as belonging to that species. The jaw is very wellpreserved. The tusk is not present, but its alveolus is plainl}-seen, and indicates a tusk slanting downward at quite a steep symphysis is short and abruptly descending. The last molar has four crests and quite a prominent keel, theinternal half of each crest is slightly in advance, the outer lialves ofthe first three crests are worn into trefoils. The tooth tapers veryslightly to the rear; there is but little cement in the valleys; thecingulum is prominent. In front of this molar the alveolus is empty. T
