16 THE GENERA OF FISHES 



Centriscus Linnseus, 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. 



n. GUNNER, Nachricht von Berglachs, ivelche Coryph.enoides rupes- 

 TRis genannt werden kann: Throndhjemske Selskab, Schriften 

 III, 1761. 



JoHAN Ernst Gunner. 



Cor5T)haenoides Gunner, 43, 50; type Coryph^noides rupestris Gun- 

 ner. 



in. SCHtEFER, 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 fltjvia- 



TILIS. 



Names perhaps not eligible as mononomial: 



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

 f er = Perca cernua L. 

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

 Cf.rnua Fleming. 



Schraitzer Schsefer, 38; type Sciiraitzer Ratisbonensium = Perca 

 schr^:tzer L. 

 Equivalent to Leptoperca Gill. 

 Asperulus Schrefer 59; type Zindel ratisbonensis Scha^fer = Perca 

 ZINGEL L. 

 Equivalent to Zingei- Oken. 

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

 =: Perca asper L. 

 Equivalent to Aspro Cuvier, not of Commcrson.
