De Toni" places this as a synonym under Dai./ta/?a turyida Ehrenb. The unfig^ured 

 description of that species l>y Elirenberg f» can nut afford any satisfactory grounds for 



uniting these two. 



Found at stations 3513, 3603, liering Sea< 



Biddulphia grundleri Schmidt, Atlas pi 118. f, 22-24. 1S8S. 



Although this might easily be considered a variety of B. pulcheUa Gray, I find 

 suflicientcontrast towarrantth*^ acceptanceof Schmidt'sname, at leastfor thepresent. 

 Not only the scarcely observable marking of the rounded ends of the horns mentioned 

 by him in the above citation, but the large, ^videly set, and prominent beads which 

 mark the valves of my specimens, instead of the more tliiclvly set l>eading or reticu- 

 lated marking of B. pukhdla, present loo strong a contrast to favor their union. 



Found at station 4013II, east coast of Honshu Island, Japan.

Boyer gives three localities for this diatom, the last being Monterey Bay, California^ 

 and marks it "rare." hi the single sounding ^^ here itai)pears, also made in Monterey 



Bay, it is abundant.

This diatom, Avell deserving the specific name given by Kiitzing, polytnorpha, was 

 found inonly one sounding. It was there unusually large and smooth.

The authors distinguished this from the similar species, T. ajrkaninn Ehrenb., ^^ T. 

 (jratunt Schmidt/^ and T. tuollcri Pant.^ It is, however, ver}- close to the latter. 



Two si)eciniens were found by me, one with a length on :<ide of 0.083 nnn. and the 

 other with a length on side uf 0.153 nnn. 1 figure this species l)ecause the drawings 

 referred to above give in bolli in.stances emphasis to the dotted centers of the beads, 

 an ns})ect entirely lacking in my specimens.
