This diatom is one of the commonee-t of tlio genu^; at the same time it is vory vari- 

 able. In consequence of both fatls it runs gradually into a number uf other species, 

 so that the list of synonyms given above could be easily increased. I have confined 

 myself to evident cases of identity, as the specific lines here are most difluult to fix 

 with exactness. t^ 



Found at stations 2807, 2808, 2823, 2923, 2929, 2G35H, 3688H, Galapagos Islands to 

 central California and Okhotsk Sea.

My specimens^ which are exceedingly abnndant in the one dredging mentioned, 

 differ from Cleve 's figure and description in some important particulars. The mark- 

 ings are much more elaborate thaTi he indicates, wliioh may have boon due to iiuule- 

 quate material, as he says his form is ''very rare.' The border of my specimens is 

 much narrower and more strongly ribbed and is withcmt the beads. Thebrancdiing 

 of the forkefl tips on the iruier side of the row of ])rocesses M'ith swollen ends is more 

 pronounced. There are other minor differences but not sufficiejit to indicate a new 

 species. The great points of resemblance are the swollen processes and the ring uf 

 Leads in the otherwise hyaline central area. 



Found at station 2807, Galapagos Islands.

This diatom is of the S. fastuos-a type, bnl hardly near t^iough to be mdted. To 

 the above references might he added the unnamed figures of Schmidt and Janisch.?>
