ON SOME NEGLECTED GENERA OF FISHES. 



By Theodoke Gill, 



Honorani Associate in Zoolo(jy. 



Dr. Charles W. Richmond recently purchased a serial in Iwclvo vol- 

 umes entitled Magazin f iir das Neueste aus der Physik and Natur- 

 geschichte, published in Gotha from 1781 to 1799, and kindly called 

 my attention to it. In the sixth volume (3. Stuck, pp. 28-38) for 1790 

 is an outline of a division of fishes according- to their teeth (Versuch 

 einer Eintheilung der Fische nach den Zahnen) by Heinr[ichJ Fr[ied- 

 rich] Linck, in which several generic names are proposed which take 

 precedence of some in general use, but happily do not otherwise seri- 

 ously disturb the nomenclature. Linck is only known by the article 

 in question, which is duh^ recorded in the Bibliotheca Zoologica of 

 Cams and Engelmann (p. 971), and b}" a prize writing: De aiialysi 

 uringe et origine calculi, referred to b}^ the editor of the Magazin. 



As the magazine is very rare, an outline of the classification seems 

 to be desirable, although there is nothing of value in it and charac- 

 ters are often erroneoush' given and misapplied.
