The tendency toward fine discrimination in fusulinid species has made necessary standardization in their study. Theories and practices of fusulinid study are herein discussed in some detail. Four new species of Triticites are described from the Missouri series of the Pennsylvanian system; one species from the Virgil series and two froim the Missouri are redescribed, and the characters of the other five known Missourian species from the northern mid-Continent are shown in graphs, thus bringing together the known Missourian species. Finally consideration is given to the ontogeny and phylogeny of the group.
