Species, ut mihi videtur, priori valde affinis, et, si 

 characteres, quibus utrnquc inclius distingui possit, firmiores 

 detexerit quispiam, valde laetabor. Forinae cellularum, saepe 

 c mnss.i, quain continent, ejusque forma, judicatac, vix con- 

 stans est. Variolates allatas, ab auctoribus saepissime species 

 descriptas, cum tantuin ramositate thalli I. ejusdem crassilie 

 inter sc difierant, specifice diversas equideni habere non pos- 

 sum, Harveyi verba de Enteromorpha erecta (var. c. nostra), 

 "Few plants are so sportive in size and ramification , and if 

 all the varieties were described the species might easily be 

 multiplied till we should have one for almost every marine 

 pool", in meam defensionem aflferens.
