THE RIVEE GOBY. 
The back is of a yellow colour, variegated with three 
or four trani'verfe patches of black. The mouth as wel 
as the head, is difproportionably large : The peftorai fin* 
are broad and rounded ; the ventral extremely 1 avail, 
having only four rays *. The anal, and two dorfal, are 
larger than ufual in hikes of the fame fize. There is a 
fpecies found in the lakes upon the continent, of fall an 
inferior magnitude to our river bull- head, and of a bright- 
er colour. 4 . 
The armed bull-head, or pogge, as it 13 called in 1 1 
north of England, is an inhabitant of the fea, muc - 
larger than the fpecies noticed, and formidable, as v.<- 
as hideous in its appearance. It is near a foot in length , 
the head triangular, and armed with a number of fharp 
tubercles upon each fide ; the fnout is flat, and turned 
up, armed alfo on the point with four ftrong eurvated 
pikes ; below the chin are a number of uni, forming 
copious beard, which adds to the threatening rfpeft ° 
this animal. The body, from the head, a confiderab 
-way down, is of an oaagonal fliape ; near the tail it ® 
comes hexagonal, and is entirely covered with large 
ny fcales, which give the body its angular form *.
