364 GENERAL SYSTEMATIC BACTERIOLOGY 



sense, that is, with a species name, apparently is that of Coats and 

 Forbes (1911, p. 242) who used the combination Meninigococcus intra- 

 cellularis. This would seem to validate the name, even though the 

 authors were not aware that they were introducing a new generic name. 

 However, it must be dated from its first use in binomial nomenclature, 

 and must yield priority to Neisseria. 



Meningokokkus. A variant of Meningococcus used by German 

 writers as a casual name. 



In binomial nomenclature apparently it was first used by Huebner 

 (1896, p. 6) in the form Meningokokkus intracellular is. Neisseria has 

 priority. 



Merismopedia. A genus of blue green algae created by Meyen, 

 (1839, p. 67). Kiitzing (1849, p. 471) described the genus as follows: 

 "Phycoma parvulum non afficum, quadratum, planum; gonidiis quater- 

 niis, solidis {Aguaticae)." Rabenhorst (1865, p. 56) gives the following 

 description: "Cellulae globosae, tempore divisionis oblongae, tegu- 

 mentis subcrassis confluentibus, 4, 8, 16, 32, 64, 128 in familias tabu- 

 latas unistratas consociatae, thallum quadratum planum libeve natans 

 formantes." One species included, M. littoralis, is a form that is proba- 

 bly to be reckoned among the bacteria. 



Merismopedia is a valid algal genus, its use in bacterial nomen- 

 clature is therefore quite invalid. However, certain writers have 

 placed in this genus bacteria which resemble Merismopedia in cell 

 shape and grouping. The bacterial equivalent is Merista Van Tieghem. 



Robin (1853, p. 331) placed Sarcina ventriculi Goodsir in this genus. 



Zopf (1885, p. 51) recognized this as a bacterial genus with the diag- 

 nosis: "Tafelcoccen. Theilungen nach zwei Richtungen des Raumes, 

 zur Bildung von Zellflachen in Tafelform fiihrend, deren Glieder 

 Spater ausser Verband treten." The only species assigned to the 

 genus was the Merismopedia Gonorrhoeae, the newly described gono- 

 coccus. As a bacterial genus, Merismopedia was also recognized by 

 Billet (1890, p. 24) with the description: "Merismopedia, zoogl^e 

 tabulaire, a elements unis par 4." Sternberg (1892, p. 17) likewise 

 included this genus in his classification of the cocci. Lehmann and 

 Neumann (1896, p. 102) conclude that all forms included in Meris- 

 mopedia should be placed in Micrococcus. The name is rejected by 

 Erwin F. Smith (1905). 



Caspary (1874, p. 104) named an organism Merismopedium Reiten- 

 bachii, which was included among the bacteria as Lampropedia Reiten- 

 hachii by De Toni and Trevisan (1889, p. 1048). He says: "Es ist
