Original Description The low trochospirally coiled test is covered with fine spines, pustules, and costellae. Its small early chambers are inflated and globirgerine-like. Its later chambers are moderately flattened both dorsally and ventrally. The last whorl is deeply notched and composed of six or seven overlapping chambers. All later chambers exhibit a double-keeled, imperforate, peripheral band. The two strongly spinose keels are parallel and close together at the posterior part of each of the later chambers but become sharply divergent toward the anterior part. The principal aperture is rounded, interiomarginal, and opens into a rather large umbilicus. Long apertural falps extend into the umbilicus, and in later chambers form a protruded, imperforate, umbilical cover-plate with accessory apertures. Size: Etymology: This species is named for the late Rudolf Noth in recognition of his work on Cretaceous Foraminifera. Extra details from original publication Remarks: Rugotruncana nothi, n. sp., is unlike any other Rugotruncana or Globotruncana known to us in the marked divergence of the two keels and in the unusually strong ornamentation of the test.
