Original Description

A cup-like distinguishes this species with tests of 0.20-0.50 mm which arise from a single, simple chamber or form a straightening spire. Juvenile tests differ from G. decurrens and similar forms by their increasing width as shown in Fig. 25, 26. Third chambers are inserted between the two alternating ones of the biserial row, and the chambers are positioned one upon the other in the whorls and with the insertion of more chambers at times distinctly widening. At the anterior, the juvenile tests show the last two chambers co bulging terminations of the test, with a broadly gaping opening in the border of the test axis. In the cross-section of the cone of the rounded off larger tests, the middle portion of the commonly damaged cone bottom remains recessed, and the chambers of the last whorl open freely with their borders into the depression of the test. All tests pore ribs which rise freely and are strongly constructed; because the chambers retain more or less the same size in the later whorls, the test surface resembles that of blackberries. Reuss shows a figure of Gaudryina siphonella Reuss from Hermsdorf in his study about the Fossil Foraminifera and Entomostraca of the region of Berlin in 1851, which may belong here.
