16 THE GENERA OF FISHES 



Centriscus Linnaeus, 336, after Gronow; type Centriscus scutatus L. 

 Monotypic, a fact overlooked by various authors who choose Centriscus 

 scoLOPAx L., 1766. 



Syngnathus Linnaeus, 336, after Artedi ; type Syngnathus acus L. 



By common usage. The earliest restriction as approved by the International 

 Commission is that of Jordan, Opinion, 45, 103, 1912. 



Pegasus Linnaeus, 358, after Gronow ; type Pegasus volitans L. 

 Monotypic. 



IL GUNNER, Nachricht von Berglachs, welche Coryph^noides rupes- 

 TRis genannt werden kann: Throndhjemske Selskab, Schriften 

 III, 1761. 



JoHAN Ernst Gunner. 



Coryphaenoides Gunner, 43, 50 ; type Coryph^noides rupestris Gun- 

 ner. 



in. SCH^FER, Piscium Bavarico Ratisbonensium, 1761. 



Jacob Christian Sch^fer. 



The descriptions in this paper are exact and very elaborate ("in 

 universum describiendibus"). The nomenclature is eccentric — in part 

 mononomial, and the names are perhaps not exactly used in the sense of 

 genera. The perch is called Perca vulgaris and again Perca fluvia- 



TILIS. 



Names perhaps not eligible as mononomial: 



Cernua Schaefer, 37 ; type Cernua seu perca fluviatilis minor Schae- 

 f er = Perca cernua L. 

 Equivalent, if accepted, to Gymnocephalus Bloch, Acerina Giildenstadt, 

 Cernua Fleming. 



Schraitzer Schaefer, 38; type Schraitzer Ratisbonensium = Perca 

 schr^tzer L. 

 Equivalent to Leptoperca Gill. 



Asperulus Schaefer 59; type Zindel ratisbonensis Schaefer = Perca 

 zingel L. 

 Equivalent to Zingel Oken. 



Asper Schaefer 59; type Asper verus Schaefer, "Streber ratisbonensis" 

 = Perca asper L. 

 Equivalent to Aspro Cuvier, not of Commerson.
