VII. 



COREGONUS LAVARETUS AND FERA. 



I give here short descriptions by Dr. Carl Yoght of the 

 above two fish; not of course adopting those descriptions 

 or opinions, but simply that students may have an oppor- 

 tunity of weighing testimony : — 



" THE GANGFISH. 



" The Lavaret (Coregonus Lavaretus or Wartmanni) of 

 the Lakes of Bourget, Geneva, and Neuenberg, appears to 

 be the same variety as the Palee blanche of the ISTeuburg 

 Lake, the Neuerling, Stuben, Gangfisch, Reriker Brewer, 

 the Blanfolchen of the Lake of Constance, the Balchen of 

 the Lakes of Zug and Lucerne, the Adlboch of the Thun 

 and Brienz Lakes, the EdeJJlsh of the Lake of Lucerne, 

 and the RenJce of the Upper Bavarian lakes. 



" boden-renke (Coregonus Fera). 



" A second larger species of the Fera (Coregonus Fera) 

 of the Lake of Geneva, the Weisfolchen or Sand-gangfish 

 of the Lake of Constance, the Blauling or Bratfish of 

 the Lake of Zurich, the Boden-renke of the Starnberg 

 Lake."
