GENERAL SYSTEMATIC BACTERIOLOGY 521 



The name is rejected by Erwin F. Smith (1905, p. 174). 



Urococcus. Urococcus was proposed as a generic name by Kuetzing 

 (1849, p. 206), for a group of algae. This author ascribed the name to 

 Hassall (1845, p. 322) but this latter author used the name Ourococcus 

 as a subgeneric designation under the genus Haematococcus. 



Miquel (1888, p. 518) used this as a generic designation for cocci 

 bringing about ammoniacal fermentation of urea. 



Beijerinck (1902, p. 37) says: 



Pour reconnaltre et distinguer les urobact^ries, M. Miquel les a classees en 

 coques qu'il designe par le nom d' Urococcus, et en bacilles qu'il appelle Urobacil- 

 lus. Dan le genre physiologique Urococcus il classe 9, dans le genre Urobacillus 

 8 esp^ces. 



The description and designation of species by Miquel have not been 

 found. However, Mace states (1912, p. 590) that the Micrococcus 

 ureae Van Tieghem is probably the Urococcus Van Tieghemi Miquel. 



Beijerinck (1901, p. 54) renamed the Micrococcus ureae Cohn as 

 Urococcus ureae. 



The nomenclatural status of the genus and the designation of type 

 species are uncertain. 



Urosarcina. A generic name used by Miquel (1888, p. 517) for a 

 motile sarcina form in urine. It is listed as a synonym of Sarcina by 

 De Toni and Trevisan (1889, p. 1044) but no species is listed in which 

 the name was used. Beijerinck (1901, p. 43) states that this organism 

 is a bacillus. It is rejected as a generic name by E. F. Smith (1905, 

 p. 174). 



Vallorillus. A generic name proposed by HeUer (1922, p. 16) as 

 the seventh in the Clostridioideae. The description given is: 



Clostridioideae that do not liquefy gelatin. They produce gas and acid in meat 

 medium but no digestion. They clot milk slowly and attack various sugars. 

 Rather slender Gram-positive rods with little or no tendency to form spores. 

 Form lenticular colonies, "coeurs jaunes," in deep agar. Many invade tissue, 

 producing oedema and gas. Pathogenicity transitory. 



Type species T. fallax {Bacillus fallax Weinberg and Sdguin) as described by 

 the Committee (p. 27), the type which ferments glucose, laevulose and maltose. 



Vibrio. A generic name proposed by Miiller (1773, p. 39) in the 

 group Infusoria crassiuscula with the generic description "Vermis 

 inconspicuus simplicissimus, teres elongatus." Other descriptions 

 of the genus as taken from the keys are "Tentaculis desV'tute, vagantes,
