It is remarkable that the same two species should also be found associated in the Conodont bed at Eighteen Mile Creek. We have 17 teeth of D. priscus, some of them in splendid preserva- tion, showing the entire root, the median denticle and all the char- acters of the species. These specimens enable us to add somewhat to the account given by Eastman, who had available only imperfect specimens. In the first place, it should be observed that there is con- siderable vari

These specimens enable us to add somewhat to the account given by Eastman, who had available only imperfect specimens. In the first place, it should be observed that there is con- siderable variation in size among the teeth, some of the larger ones being twice as high as the smaller ones. Secondly, the ornamenta- tion, which consists of striae spiraling gently upward from base to tip of tooth, varies considerably in the number and prominence of the strife. Some teeth have seven or eight striae, others as many as a dozen or more. Frequently short striae are interpolated between the long ones in the basal portion of the tooth; or the striae may be.
