Part III. Systematic Descriptions: Order ATREMATA Beecher 1891 Superfamily OBOLACEA Schuchert 1896 Family OBOLIDAE King 1846 Available to Purchase
Obolacea (Schuchert, in Zittel, 1913, p. 371) with thickened and striated pedicle regions; ventral pedicle area traversed by a groove. Life habits probably like those of Lingula and allies. O zarkian and C anadian O bolidae : Obolus, Lingulobolus, Lingvlella, Lingulepisl, Paterula, Leptobolus, Westonia. D iscussion : There are no known internal characters which will allow a satisfactory division of the Obolidae into two subfamilies. According to present knowledge the Obolinae and Lingulellinae are divided on the basis of external form. This is not a practical division, because there are elongate species assigned to Obolus and oval forms placed in Lingulella. The authors prefer to recognize one family only. Structurally, Paterula appears not to belong with the Obolidae, but the authors are unable to place it elsewhere. Bröggeria, hitherto placed in this family, is excluded because of its very apparent relationship to Elkania of the family Elkaniidae.
