36 THE GENERA OF FISHES 



of Gronow was published in 1763. His names have been accepted as 

 eligible by the International Commission of Zoological Nomenclature. 



In this paper we give a list of these genera of Klein together with 

 the Linnasan type, each as understood or as indicated by the present 

 writer. In deciding on the type, the writer has been materially aided 

 by the possession of a copy of Klein's Historia Piscium Naturalis, which 

 was once the property of his commentator, Dr. Johann Julius Walbaum 

 of Greifswald, and which contains profuse annotations in Walbaum's 

 own handwriting. 



Dr. Walbaum himself published in 1792 [Petri Artedi sued Genera 

 Piscium, 589-587) a classified record of the genera of Klein, but without 

 actually accepting these as part of the System. Later Walbaum printed 

 an Index to all these early names of various authors, as Ichthyologia 

 Enodata sive Index Rerum (Leipzig, 1793). In this Index the generic 

 and other names used by previous writers are arranged in alphabetical 

 order with indication of the Linnaean synonymy. This again does not, in 

 the view of the Zoological Commission (Opinion 21), involve the accept- 

 ance of any of these names. A reprint of Klein's Historice Piscium 

 Naturalis was published, with notes by Walbaum, in 1802. 



In the Gcsellschaft Schauplatz Klein's names are frankly adopted, 

 and the chief serious objection to be raised is that the species are named 

 polynomially. We here omit those names in the Schauplatz, as Acipen- 

 SER, Cyprinus, Xiphias, etc., which had been used by Linnaeus and were 

 already accepted in the System with the same significance. We are in- 

 debted to Mr. Carman for the verification of the list and for the insertion 

 of page references. 



Illustrations of the method of the elliptical and disorderly Schauplatz 

 are the following. In vol. I, p. 918, 1777, w^e read: 



"Botte. Rhombus, ein Kleinisches Fischgeschlecht, welches Linne, 

 Pleuronectes G. 163, Miiller Seitenschwimmer, Richter Butten nennt," 

 etc. Description follows. 



In III, p. 512, we find: "Greete, Kleinische, eine Art platteise, But- 

 ten, Richter: s(iehe) Botte, Rhombus, des Kleins una unsern Artikel 

 Th. I, s. 918 ; desgleichen Plunder, Passer 4 des Kleins und unsern Artikel 

 Th. Ill, s. 151" etc. 



"Passer 4" is the species called "Passer asper s(eu), squamosus 

 Rondelet. This species is Pleuronectes limanda L. With (eight) 

 other species named polynomially, it is set forth in the Schauplatz, after 

 Klein. The quotations from Miiller probably refer to the Niirnberg 

 Edition of the Systeina Natures, published in German by Professor Philip
