But the fish that enter the Pamisus are of quite a different kind, as the water is pure and not muddy like the rivers which I have mentioned. The grey mullet, a fish that loves mud, frequents the more turbid streams. The rivers of Greece
contain no creatures dangerous to men as do the Indus
and the Egyptian Nile, or again the Rhine
, the Euphrates
. These indeed produce man-eating creatures of the worst, in shape resembling the cat-fish of the Hermus and Maeander
, but of darker color and stronger. In these respects the cat-fish is inferior.
