Description
Test large, early portion planispirally coiled, later rectilinear, wall agglutinated, with interior structure of walls and septa simple, aperture terminal, cribrate. [Differs from Ammobaculites in having a multiple aperture and from Haplophragmium in haviing an early planispiral, rather than streptospiral. coil. Stylolina has been regarded as a
synomm of Haplophragmium (*762), but because of its multiple aperture, is here classed as a synonym of lituola.]
