 h is ili ail »t!'u 1 i nanii Ehrenb. Kin/., included above, should be attributed 



i" Kutzing. Bia firsl figure and descriptioo represent a totally differenl diatom, as do 

 some of the subsequent copies of it andexsiccati bo determined and cited above, which 

 [ have also excluded. The figure on plate 30 is, however, a good representatioa of this 

 Bpecies, as is that cited by Van Beurck. There is very close similarity between the 

 present Bpecies and E. hyndmanii W. Smith, bo much so thai their separation, 

 though upheld by De Toni and others, appears to me decidedly doubtful. In fact . my 

 specimen is aboul midway between the two, having the strongly Lowed dorsal outline 

 and broad rounded apices of E. hyndmannii together with the beading of E. turgida, 

 especially the large beading along the ventral margin as Been in the zonal \ iew. 

 Found at station 2882, off < Oregon.
