 Thalmann, Eclog. geol. Helvet., Vol. 25, Pt. 2, 1932, p. 298, refers these figures to the synonymy of /. acuta 

 Brady. No other reference to this synonymy has been found and no reasons are given, so Cushman, Earland 

 and others have been followed here in retaining Brady's Jaculella obtusa as a valid species.
