There is some doul.t of the propriety of inclutlinj,^ lu^re V. rmtricom, especially il' we 

 take into ronsideration Ehrenberg's aulhorship. It .should eilher be h'fl out of ihis 

 category or referred to as N. rcntricom Ehreid). .-rr. <let. Doiik. as above. The con- 

 trast is con.siderable even in that ca-se, because of the striking stauros. But if wo take 

 into consideration N. Imlinszhji (see above), wo find a perfect gradation from one phase 

 to the other. Donkiii has included liere several spfH'ies that have absolutely nothing 

 in common with this species except the trinodal outline; thu.'s, N. ]epto(jongyla 

 Ehrenb. a O'Meara offers sucli absurd figures of this diatom & that they are much 

 worse than none.

De Toni here includes Pinnularia scutellum O'Meara,'' which is Navicula saitellnm 

 O'Meara.f; This is a gross error. O'Meara's form, judged l)y its figures and <lescrip- 

 tions, is a truly costate-ribbcd diatom which shows none of the double-rowed l>eadino' 

 so characteristic of N. smithii. I tliink if such were present, it could not liave been 

 twice overlooked by O'ileara. Clevee questions Van Heurck's determination of 

 N. scutellum O'Meara, / referring the figure doul:)t{ully to N. smithii Breb. It is some- 

 thing like N. smithii, but in the absence of the beading I tliink it is a poor figure of 

 O'Meara's species. Van Ileurckff has transferred ScMzoncma smithii C. Ag. to Navi-
