385. GISTEL (1848). S'aturgeschichle dcs Thierreichs fiir hohcrc Schulen. 



Johannes Gistf.l. 



A remarkable dull and confused publication, not hitherto noticed by 

 ichthyologists. Gistel speaks feelingly of his "hochst miihsamcr Vcr- 

 gleichung, zeitraubendcn Nachschlagcns, in vielen hundcrt Werken, etc., aus 

 mcincn Manuscripten aufzufiihrcn". It is not often that so fatiguing a piece 

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

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

 animals ( "rien niedrigslcn Thierklassen"). 



The following may replace names actually preoccupied : 



Abron instead of Platystcma.
