land being its type. It is probable, however, that several 

 of the subgenera recognized by Jordan and Evermann 

 should stand as valid genera. Among these are Nano- 

 stoma, Putnam; Nothonotus, Cope; Torrentaria, Jordan 

 and Evermann; Oligocephalus, Girard; Nivicola, Jordan 

 and Evermann: Rafinesquiellus, Jordan and Evermann: 

 Claricola, Jordan and Evermann; and Catonotus, 

 Agassiz. 



Amia Gronow 



In Opinion 20, it is decided that the generic names 

 of Gronow (1763), with polynomial names for species. 

 shall be accepted, their date being subsequent to that of 

 the Tenth Edition of the Systaema Naturae (Jan. 1. 

 L758). The case o( Brisson (1760) in Birds (Opinion 

 37), is exactly parallel except that the names o( Brisson 

 have come into more general use than those of Gronow. 

 Amia Gronow (1763) must displace Amia Linnaeus 

 (1766). Amia L. thus becomes Amiatus Rafinesque 

 (1815), and the species becomes Amiatus calms. Amia 

 Gronow replaces Apogon Lacepede (1S02). and the type 

 species becomes Amia imberbis. Cyclogaster Gronow 

 must replace Liparis (Artedi) Scopoli, 1777. The type 

 species o\ both is Cyclopterus liparis L. Collyodon Gro- 

 now must replace Scants Forskal (1775). Scarus Gronow 

 ( L763), being a Labrus. The type ot' Callyodon is Sca/rus 

 croicensis, Bloch. Enchelyopus Gronow (1763) must re- 

 place Zoarces, Cuvier 1829, the type oi' each being Blen- 

 nius viviparus L. Hepatus Gronow (1763) must replace 

 Teuthis L. (1766) and Acanthurus Forskal. 1775. the 

 type of each being Teuthis hepatus L. The accepted 

 genera Holocentrus, Pholis, Eleotris, Albula, Synodus, 

 Umbra, Leptocephalus and Pteraclis must date from Gro- 

 now (17t>-'>). not from later usage. 



CeraUchthys Baird and Girard (Opinion 22) 



The name Ceratichthys Baird and Girard. monoty- 

 pic. being based on Ceratichthys vigUax Baird and Gi- 

 rard. must replace Cliola Girard (1856) based on the 

 same species. Ceratichthys of Girard (1856) is synony- 

 mous with the earlier Nocomis o( Girard. This decision 

 conserves also the genus Cymatogaster, Gibbons (C. ag- 

 gregatus). 



In Opinions 23 and 24 the generic names Cheilodip- 

 tent* Lacepede (vice Aspro Commerson) and Antenna- 

 rius (Commerson) Lacepede vs. Hist fin Fischer (1813) 

 are conserved.
