De Ouis Riuatricis. ca. 111.
RIuatrix is a certaine venimous Ser∣pent, that infecteth water, and her egges be lyke to the egges of an Adder, that is called Colubet, and they be lesse & more speckled, and bee worse and more venimous. The serpent Riuatrix sitteth on her egges nigh waters and welles, and infecteth them, and corrupteth with full wicked venim. Of this Serpent Iu∣can speaketh and saith, that Riuatrix de∣fileth waters.
