Skin smooth. No spines on the head, except on the praeoperculum, 

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

 suboperculum, the spine of which is still smaller. The lateral line 

 iTins 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 first 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 tins with 7 or 8 forked rays : Cottiis gobio, Valenc. —

A. Rays of the ventrals forked : Cottv^ gobio, Axtedi,L.,Ekstr., 



or Cottus affinis, Heck. — Scandinavia.

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

* Sir John Richardson (Faun. Bar. Amer. Fish. p. 42), and Girard (l. r. p. 36), 

 from him, state, in the description of Coffus coqiiatus : — " The anug, situated pre- 

 cisely as in yohio. is rather nearer to the snout than to the insertion of tlie nwidsA." 

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

 C. coynatus, both fishes must be different.
