ABIETINARIA, Kirchenpauer. 



The genus Abietinaria includes a group of species distinguished 

 from those belonging to Sertularia, Sertularella, and Thuiaria, by 

 the fact that the operculum is attached to that wall of the hydro- 

 theca which is nearest the internode (adcauline), and is single-valved ; 

 and from Dip/iasia, because the hydrothecae are not strictly opposite, 

 are flask-shaped, and taper to a small aperture.
