Original description Diagnosis.⎯Schwagerinid characterized by presence of welldeveloped cuniculi, heavy axial filling concentrated in earliest volutions, and very high folds typically with parallel sides. Discussion.⎯This very distinctive form does not closely resemble any other described genus. Cuniculinella Skinner and Wilde, 1965 differs in its distribution of axial filling and nature of the septal folds. Nigribaccinus n. gen. somewhat resembles Skinnerella Coogan, 1960 but has higher septal folds with parallel sides and a concentration of axial filling in the inner volutions. Nigribaccinus also lacks the heavy secondary deposits on the upper parts of the folds found in the type species of Skinnerella. Nigribaccinus n. gen. differs from Iranella Leven, 2004 in lacking a juvenarium and in generally having a much larger proloculus, heavier axial filling in the early volutions, and higher septal folds with decidedly parallel sides.
Occurrence: Artinskian(?), California.
