tum fossilium una continentur, liceat mihi exponere ma- 
ximam difficultatem, quae occurrit in quibusdam generibus 
amplissimis elaborandis, in quibus nec synonymiam nec 
alias pra^cipuas qusestiones omnino persolvere potui. 

Enormis specierum copia, frequens difficultas earum 
identitatem comprobandi, defectus speciminum authentico- 
rum, innumera studia nuper in lucem edita, absentia ico- 
num multarum specierum, instabilitas systematum de Ba- 
cillarieis, penuria descriptionum plurimarum specierum tara 
clari Ehrenberg quam Schmidt etc, commutatio ad unicuin 
typum (micromillimetra) mensurar;im microscopicarum me-

re nolim, tamen characteres immutabiles et semper sat 
conspicuos in rhaphes seu pseudorhaphes praesentia vel ab-
