385. GISTEL (1848). Naturgeschichte des Thierreichs fUr hohere Schulen. 



Johannes Gistel. 



A reiTiarkable dull and confused publication, not hitherto noticed by 

 ichthyologists. Gistel speaks feelingly of his "hochst miihsamer Ver- 

 gleichung, zeitraubenden Nachschlagens, in vielen hundert Werken, etc., aus 

 meinen Manuscripten aufzufiihren". It is not often that so fatiguing a piece 

 of work presents itself in such a crabbed form. Gistel insists that personal 

 names of genera are allowable only in Botany and in the lowest classes of 

 animals ("den niedrigsten Thierklassen"). 



The following may replace names actually preoccupied : 



Abron instead of Platystoma.
