Although 1 agree wi ill D<* T(mi in uuiking Cocconrmavornfifum Ehronb. wyntuiymous 

 with the present spociew, I recognize that there is gmund fnr <iueRtioning this, C cor- 

 nutnm lieing more suddenly attenuat^'d on eilh(T side of ihe middle and, tlierefore, 

 with narrr)wer apices than C\ lanceolaium^ wlience the nanio. But I do not tliink this 

 is sufficient to separate them. I have Jio question in regard to C. asperum Ehrenb,, 

 which I'leve holds as a distinct species. Ehrenberg's own figures of this are indistin- 

 guisliabl(3 from his C. lanceolaium, (deve has evidently a somewhat di ff(^iH4it concep- 

 tion of this diatom, as is shown by his unii i ng with it su<'h forms as Pantocsek's Cymhella 

 gi(jantca,^ which seems to me quite distinct from Ehrenberg's C. asperum. I therefore 

 make Clevc's species synonymous only in part. Doubtless this species and C, gas- 

 iroidcs Kutz. interlock. 



Found at station 2882, off Oregon.
