and fry of salmon and trout. Coitus gobio is the commonest 

 species of Europe. Cottus ictalops is the most abundant of the 

 several species of the eastern United States, and Cottus asper in

 in America. It is composed of smaller species with fewer

Trachidermus ansatus is another river species, the " mountain-

 brand on its cheek, conspicuous in life. 



The chief genus of Atlantic sculpins is Myoxocephalus, con- 

 taining large marine species, in structure much like the species 

 of Cottus. Myoxocephalus bubalis is the European fatherlasher, 

 or proach; the European sculpin is Myoxocephalus scorpius. 

 The very similar daddy sculpin of New England is Myoxocepha- 

 lus groenlandicus. This species swarms everywhere from Cape 

 Cod northward.
