 whence it is in some places called the finger-

8. Salmo Salvelinus. The red char, or torgoch. 

 About a foot long. Back of a purplish green,

 clear streams which have their source in limestone 

 hills. It is caught, from ten to twenty inches long, 

 in the Wye ; in the Derwent, and the Rye in the

 the north of the one last mentioned. It was called
