 Clavicula Hnkerii Pant. Beitr. Bacill. [Jng. 3: pi. l.f.50. L893 

 Pantocsek figures the lower portion only of the outer plate of this diatom and 

 names it Clavicula Icirikerii. There can be no doubl of its being tin- above. It bo 

 happens thai the form found by me lias precisely the irregularity of beading of the 

 centra] band near the lower extremity thai Pantocsek has figured. Whether this is 

 general or not, I do no1 know. I have. likeGrunow. found il to be a very rare diatom. 

 Leud.-Fort. in the citation above erroneously attributes the name to Grunow.

 The generic name Echinella of Acharius " was applied by Ehrenberg under a mis- 

 apprehension, the name being that of a clustered form of marine ovae similar in 

 appearance to clusters of Climacosphenia. 6 Ehrenberg corrected the generic name 

 in the firsl cital ion u r i\ en above. 



Found at station 2920H, Hawaiian Islands.

 This genus has close affinity with Dimeregramma Kali'-, and the doubtful genus 

 Glyphodesmis Grev. It i-. however, well marked from these by the internal trans- 

 verse sepia, especially those that divide off the central and the terminal hyaline 

 areas from the resl of the valve. 1 am nol in favor of including here anj of the mem
