Grove has suggested " this being only a variety of B. (dwardait Febiger. & I have dis- 

 cussed the impossibility of looking on 1hese two as the same species under the heading 



of B. edwardsii above. 



I look upon figure 5 in the above citation from Schmidt's Atlas as an entirely dis- 

 tinct diatom. 



Found at stations 2844, 32G3II, off Alaska Peninsula and Aleutian Islands.

The question of the substitution of the name Jh'eldvlphia biddulphiana (J. E. Smith) 

 BoyerjC for the above depends on whether or not the figurci^ given by Smith (/ are iden- 

 tical with this species. There should be no question of such identity liefore a 

 name like this one, of long standing and adopted in nearly every diatom work extant, 

 is discarded. In this case two facts should be borne in mint!, first, that this species is 

 similar to several other species generally recognized as w(trthy of separate rank which 

 are ecpudly like the figures of J, E. Smith. Such are Biddulphia grundleri S( hniidt,^ 

 which is not united with this species by either De Tojii or Boyer, and Biddulphia 

 tridens Ehrenb. / The second fact is that the figures of J. E. Smith are not those of one 

 species. T have, therefore, not followed Boyer in making the abpve specific name a 

 synonym under that of J. E. Smith's. 



This widely distributed species is remarkably infrequent in the Pacific dredgings 

 examined by me. In none of the following gatherings -was it at all abundant. 



Found at stations 2807, 2808, 2920H, 3604.. Galapagos Islands, Hawaiian Islands, 

 and Bering Sea.
