It is doubtful if E. uestervianii (Ehrenb.) Kl'itz. . in<4uded abovo, should l)o attributed 

 to Kiitzing. His iirst (igun^ aud dt'scriptiun represent a totally diffi'rent diatom, as do 

 sume of till* subsequent copies of it and exsiccati so determined and cited above, whitli 

 I have also exchuh^d. The figure on plate 30 is, liowc^ver, a good representati(m of lids 

 ppfH'ies, as is that cited by Van Heurck. There is very close similarity l)et\v(HMi the 

 present speei(^s and E. hyndmnnii W. Smith," so much so that their p(*paration, 

 thongli uph(4d l^y Do Toni and othersj appears to me decid(nlly doubtful. In fact, my 

 specinuMi is about midway between llie two, having the stn>ngly bowed dorsal ontHiie 

 and broad rounded apices of E, hyndmannii together with the l^eading of E. turgida^ 

 especially tlu^ large beading along tlie venlial margin as seen in the zonal view.
