 Although I agree with De Toni in making Cocconema cornutum Ehrenb. Bynonymous 

 with the present species, I recognize that there is ground for questioning this, ( 

 nutum being more suddenly attenuated on either side of the middle and, therefore, 

 with narrower apices than C. lanceolatum, whence the name. But [do not think this 

 is Bufficienl to separate them. I have no question in regard to C. asperum Ehrenb., 

 which ( !leve holds a- a distinct Bpecies. Ehrenberg's own figures of this are indistin- 

 guishable from his ( '. lanceolatum. < !leve has evidently a somewhat di fferent concep- 

 tion mi* this diatom, as is Bhown by his uniting with it such forms a- Pantocsek's ( r ym6< lla 

 gigantea, which seems to me quite distinct from Ehrenberg's C. asperum. I therefore 

 make Cleve's species synonymous only in part. Doubtless this Bpecies and I 

 troides Kiitz. interlock.
