There is a poesibilitj of questioning the last Bynonym, as the diagnosis ie nol thorough 

 and the figure is plainly very carelessly drawn. I do not think the doubt is Btrong 

 enough to warrant this form receiving separate rank.

 Though Johnston's specific name precedes that of Arnott, it had been preempted 

 by < rreville for an entirely different diatom. a The genus < rephyria, not having been 

 constituted, Johnston rightly placed hie species in Achnanthes; for it should l>e 

 noted the two genera are. together with Entopyla, quite similar in structure and in 

 mode of growth. The specimen found by me is the short and robusl variety called
