[From introduction:]
Discrete scolecodonts are plentiful in the Delaware limestone of Devonian age and all localities examined produced scores of specimens. This study does not by any means include all the forms that probably occur. Since the matrix is limestone and subject to some agitation at the time of deposition, complete assemblages of jaws were not found. Also the jaws are secured from the limestone by treatment with acid, which tends to separate them. Occasionally a maxilla I or II was found with a smaller jaw adhering to it in possible articulation. During the past few years a number of paleontologists, Kielan-Jaworowska (1961), Kozlowski (1956), Lang (1949), have erected new genera for articulated scolecodonts or assemblages in complete disregard for the International Rules on Zoological Nomenclature. Due to certain problems and disagreements conodont specialists are apparently having difficulties in working out a classification and nomenclature for their disjunct specimens and assemblages. A dual nomenclature has been the result. It may be that scolecodont workers have followed unwittingly along this rather dubious path of unsettled issues and for this reason have erected unnecessarily an illegal dual nomenclature. The jaw apparatus of modern and fossil polychaete is relatively simple. A scolecodont jaw assemblage usually contains a jaw of a well established fossil genus based on an existing genus. Thus there seems to be little reason for new genera for known forms and a dual nomenclature in scolecodont classification. In this paper the genus Paulinites, Lang, 1947, is placed under the genus Nereidavus, Grinnell, 1877, and the genera Vistulella and Mochtyella, Kielan-Jaworowska, 1961, are included under the genus Staurocephalites, Hinde, 1879. Kielan-Jaworowska has taken exception in a paper (1961) to the use of the word “fossa” for the muscle cavity of an annelid tooth and has introduced the term “pulp cavity.” This term is used in the description of the vertebrate tooth, which is in no way homologous to the annelid tooth. The use of the word “pulp” implies that it is the same material found in the cavity of the vertebrate tooth. Anatomically the word “fossa” (Latin: ditch or trench) is in common use. Webster's Unabridged Dictionary defines fossa (anat.) as a pit, groove, cavity or depression of greater or less depth. The Century Dictionary defines fossa as any depression, pit or hollow in a structure, specified by a qualifying term. Zoologically, a fossa is described as a depression or a deep pit in the hard integument of an animal, often opening into a cavity and serving for the point of attachment of an organ. More than 40 examples are given for the use of the word. It may be that the term “pulp cavity” was adapted from conodont terminology which is also of a questionable nature.
