The dorsal structure of this genus is precisely like that of Pentamerus in composition and most nearly resembles that of Platymerella in the brevity of its septa. discrete, with more or less long brachial supports. The only genus is Strlcklandia Billings of the Silurian. The origin of this family is not yet known, but it may have come out of camerellids. Instead of retain- ing the shell form of the camerelHds, however, the Stricklandida; developed into wide-hinged types. It is possible also that the stricklandids came out of a much O (D O O C) s. o.
