* In this case the name given by D'Orbigny in 1846, yields precedence 

 to that applied by Von Hagenow in 1842, unless the want of full informa- 

 tion about the species when mentioned by the latter interferes. 



t Dr. Reuss observes that the Riigen specimens have no mouth-valve, 

 but otherwise resemble D'Orbigny 's Valvulina yihhosa. We are satisfied 

 that the latter is a true Valvulina, as well as Reuss's Valmilina sjncula 

 from the Bohemian Chalk.
