Toni, Syll. Alg. 2: 102. L891. 

 TIm' claim made by Leuduger-Fortmorel, above, that Schmidt's figures, above, are 

 ii"i Gregory's spectabilis, but a distinct Bpecies, which he also figures and to which he 

 gives tin' specific name /urcata, i- supported by I><- Toni, above. I <1<> not agree with 

 this view, hiu tak<- the position stated by Cleve* that Schmidt's and Leudugei 

 in* >!< 1 "> forms ai'' only a variety of < rregory's Bpecies. A careful reading <»t" < rregory's 

 long description of this diatom will make it evident that the only particular in which 

 ii fails to correspond with Schmidt's figures i- in the forking of the inner ends of the 

 striae on the dorsal Bide. Gregory Bays his specimens were very dimly Btriated on 

 that Bide, bo much bo that though the Btriae were evident near the dorsal margin, they 

 faded away toward the inner ends. Without doubt tin- tad prevented hi- noting the 

 forking of these striae; though it oughl i<» be added that this forking is byno means 

 invariable, a- is !<■ !><• seen by comparing Schmidt's figure '_'•> with his figure 21. So 

 !u\ experience goes, the figure of Leuduger-Fortmorel Beems overdrawn in the 

 irregularil y of the Btriae. 



Found at station 3698, off Honshu Island, Japan.
