 This fish, according to Willougliby, is found in the lakes and rivers of Yoik- 

 shire, Lincolnshire, and Oxfordshire. Pennant and Bloch, inconsiderately re- 

 fer this species, so well described by Willoughby. to the Erythropthalmus of 

 liinnfeus, which is also the erythropthalmus of our venenble ichthyologist. 

 The serrated spinous ray of the dorsal fin has induced me to place it here 

 along with the Barbel, from which, however, it seems to differ, generically, in 

 shape, and the absence of a beard. It may be termed, after "Willoughby, 

 'Siv'S^t.'Lio Jluviatilis. <
