Both figures are one-eighth natural size, a, bottom view; 6, top view ; 6', side view; V, end view; c, face for coracoid ; d, margin nest to median line ; e, inner front margin ; p, posterior end. The teeth of Diplodocus are cylindrical in form and quite slender. The crowns are more or less compressed transversely and are covered with thin enamel, irregularly striated. The roots are long and slender and the pulp cavity is continued nearly or quite to the crown. In the type specimen of Diplodocus there are four teeth, the largest of the series, in each premaxillary; nine in each maxillary, and ten in each dentary of the lower jaws. There are no palatine teeth. The jaws contain only a single row of teeth in actual use. These are rapidly replaced, as they wear out or are lost, by a series of succes- sional teeth, more numerous than is usual in these reptiles. PL XXVI, fig. 2, represents a transverse section through the maxillary, just behind the fourth tooth. The latter is shown in place, and below it is a series
