Original Description

[Brady, 1884, op. cit., p. 599]: "Test spiral, more or less rotaliform, consisting of from two to three convolutions; earlier chambers small and regular, later segments, especially the final one, elongated at their free margins and spreading radially; aperture usually large and furnished with a thickened lip or border. Diameter, 1/65 inch to 112o inch (0.4 to 1.27 mm) or even more." 

Extra details from original publication
"A very singular modification of the type, and one that has not hitherto been described. The earlier segments are commonly regular and trochoid, but the later ones are much elongated and spreading. In some specimens, generally of small size, the final segment only is extended, like the index finger of the hand, but in others, two, three or more chambers radiate in palmate fashion. The apertures of the chambers have thickened or lipped borders. lt is a rare form, and usually of small size, 1/50 inch (0.5 mm), but in one dredging specimens have been met with measuring 1/17 inch (1.5 mm) in diameter."
