that the three specific names, cegnatus, viscosus, and quiescens, 
and the generic name Uranidea, should be suppressed, as 
referring to a species which had been before described as 
Cottus gobio. ‘The correctness of this opinion I will endeavor 
to show in the following pages. 
The best description of the gobio which I have been able 
to find, is that given by Artedi. My attempt will be to show
