Obs. Generi Merenice Reinsch anno 1888 instituto pro Merenia 

 microclaclioide, qiue vero Heterosiphonice speciem sistit, serius 

 Merenia inconspicua relata fuit, jam antea nomine Polysiphonice 

 inconspicuce ab eodem auctore descripta. Nomen Merenice, etsi 

 antiquius, clarus Schmitz prsetermisit, novum nomen Colaco- 

 dasyce exhibens.
