Skin smooth. No spines on the head, except on the pra^operculum, 

 which is anned posteriorly with a small curved spine, and on the 

 suboperculiim, the spine of which is still smaller. The lateral Line 

 iims nearly along the middle of the body, and terminates in the 

 middle of the root of the caudal. Vent rather nearer to the snout 

 than to the tip of the caudal* ; the ventrals do not extend to the 

 vent ; the height of the fii'st dorsal is more than one-half of that of 

 the second. Pectoral, dorsal, caudal, anal, and sometimes the ven- 

 tral fins dotted with blackish. 



Fresh waters of Europe, and probably of Northern Asia. 



I. Pectoral fins with 7 or 8 forked rays : Cottus gobio, Valenc. — 



France. 



II. Rays of the pectorals simple. 



A. Eays of the ventrals forked : Coifets r/o6('o, Artedi, L., Ekstr., 



or Cottus affinis. Heck. — Scandinavia. 



a. Many specimens. Gotha Eiver, Sweden. 



B. Rays of the ventrals simple. — Germany ; England. 



h. Adult. Austria. 

 c. Adult. Dalmatia. 



* Sir John Richardson {Faun. Bor. Amer. Fish. p. 42), and Girard (/. c. p. 36), 

 from him, state, in the description of Cottus cognatus : — " The anus, situated pre- 

 cisely as in gohio, is rather nearer to the snout than to the insertion of the caudal." 

 Tins is wrong, with regard to the European C. gobio ; and if it be correct as to 

 C. cognatus, both fishes must be different.
