and fry of salmon and trout. Cottus 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 
streams of the Pacific Coast, though very many other species

exist in each of these regions. The genus Uranidea is found 
in America. It is composed of smaller species with fewer 
teeth and fin-rays, the ventrals 1, 3. Uvanidea gracilis is the 
commonest of these, the miller’s thumb of New England.

Trachidermus ansatus is another river species, the ‘‘ mountain- 
witch’? (yama-no-kami) of Japan, remarkable for a scarlet 
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 grenlandicus. This species swarms everywhere from Cape 
Cod northward.
