 (TTona, mouth). 



Aplostoma Canu, Comptes Rendus, vol. 103, 1886, p. 1025. 



Type of genus, Aplostoma hrevicauda Canu, monotypic. 



Aplostoma was used by Moquin-Tandon in 1885 for a genus of moUusks. 



Genus ASPIDISCU8 Norman. New name, 8AC0DISCUS (a&Kos, shield; SlaKos, 

 carapace). 



Aspidiscus Norman, Report of British Association for Advancement of 

 Science, 1868, p. 298. 



Type of genus, Aspidiscus fasciatus Norman, monotypic. 



Aspidiscus used for genus of polyps in 1825 by Konnetchtedy. Norman's 

 genus not accepted by Brady in 1880, but restored by Sars in 1904. 



Genus AXINE Oken. NAOBRANCHIA Hesse (?), 1863. 



Axine Oken, Lehrbuch der Natunrgeschichte, 1816, p. 357. 



Type of genus, Axine bellones Oken. 



Oken's species has never been identified, but from his description was prob- 

 ably identical with Hesse's species. Whether this be true or not, the name 

 Axine was used by Abildgaard in 1795 (1794 according to Sherborn) for a 

 genus of Vermes. 



Type of Naohrachia, Naobranchia cygniformis Hesse, monotypic. 



Genus BELI8ARIU8 Maupas. PHYLLOONATHOPUS Mrazek, 1893. 



Belisarius Maupas, Comptes Rendus, vol. 115, 1892, p. 135. 



Type of genus, Belisarius viguieri Maupas, monotypic. 



Scourfield in .Tourn. Quekett Micros. Club, Nov. 1903, made MrAzek's mono- 

 type identical with that of Maupas. But the name Belisarius was used for a 

 genus of arachnids by Simpson in 1879, and hence Mrazek's genus name must 

 be substituted for it. No other author has noted either monotype. 



Genus BRYAXIS Sars. New name, COMANTENNA (Comans, hairy; an- 

 tenna, feeler). 



Bryaxis Sars, Crustacea of Norway ; Copepoda Calanoida, 1902, p. 35. 



Type of genus, Bryaxis brevicornis Sars, monotypic. 



Sars explained that this was a manuscript name applied to the genus by 

 Boeck, but Leach had used the same word for a genus of beetles in 1817, 

 and Kugelann also for a genus of Coleoptera in 1794. 



Genus CALIGINA P. J. van Beneden. TREBIU8 Kr0yer (?), 1838. 



Caligina Beneden, Memoires de I'Academie royale de Belgique, vol. 33, 1861, 

 p. 127. 



Type of genus, Trebius caudattis Kr0yer, (1838), monotypic. 



Beneden's type species was described but never figured, and from the de- 

 scription must have belonged to Kr0yer's genus. 



Genus CAMPTONYX Lilljeborg. New name, CAMPELLA (Kainrr!, twisting or 

 winding). 



Campionyx Lilljeborg Ofversigt af konglige Vetenskaps Akademiens, For- 

 handlingar, vol. 32, 1875, p. 11.

Lilljeborg's genus name had been used in 1858 by Bensdorf for a genus of 

 univalve mollusks and also by Heller for a very different genus of Crustacea. 



Genus CEYLONIA Thompson and Scott. New name, CEYLONIELLA.
