Society at large could best carry out the plan, and after 

 some discussion the resolution was passed. 



On motion of Mr. Cummings it was voted that the com- 

 mittee be nominated by the chair. 



The chair nominated Rev. Mr. Waterston, Mr. Bouve and 

 Dr. Gould. Mr. Bouve desired to withdraw his name, as 

 circumstances would prevent his giving his services as a 

 member of such committee. Dr. White being nominated in 

 his place, the committee as thus foiTiied, Rev. Mr. Waterston, 

 Drs. Gould and White, were elected unanimously. 



Mr. T. T. Bouve announced that at the next meeting the 

 Building Committee w^ould make their report and suiTender 

 the Building into the hands of the Society. 



Professor A. E. Yerrill, of Yale College, was elected a Cor- 

 ponding Member, and Dr. Alexander M. Wood a Resident

Note on Ehabdonema mirificum. By Charles Stodder. 



Professors W. H. Harvey and J. W. Bailey published in the Proceed- 

 ings of the Academy of Natural Science of Philadelphia, October, 1853, 

 a list and descriptions of new species of Diatomaceae, collected by the 

 United States Exploring Expedition, under Captain Wilkes. One of 

 the new species they called Hyalosira punctata, which they describe 

 thus: "Frustules large, united in long chains, rectangular, subquadrate, 

 transversely and uninterruptedly vittate, granulate in the middle of 

 the frustule, the others furnished with a series of conspicuous puncta.'* 

 Habitat, Tahiti; with no figure. 



Professor AVilliam Smith, in the second volume, page thirty-five, of 

 the Synopsis of the British Diatomacese, pubhshed in 1856, mentions in 

 a gathering from Mauritius, the occurrence of a new form of Rhabdo- 

 nema, to which he gave the name of R. mirificum, and partially describes 

 it as a "magnificent species with alternate and cribrose septa." He 

 published no figure, as it was not a British species. 



In the Journal of Microscopical Science, Vol. vi., p. 92, 1858, Dr. 

 Arnott gives some of the characters of R. mirificum, but no figure. 



In the same Journal, for 1859, Vol. vii., p. 180, ]\Ir. Brightwell 

 quotes Arnott, and gives a figure, plate ix, figure 11. Ralfs in 

 Pritchard's Infusoria, fourth edition, 1861, page 805, copies Smith 

 and Arnott, and gives a reduced copy of Brightwell's figure.
