Related to the curious eyeless proteus, found in the celebrated cavern
of Adelsberg, is an animal very much larger, called the necturus,
inhabiting the waters of the Mississippi, and several southern lakes.
It is a creature nearly three feet in length, with a thick body, and,
being designed to live in daylight, possesses eyes. It is between a
fish and a reptile, as it is furnished with large, well-tufted gills;
and, at the same time, has four legs, and four toes on each foot, though
it is destitute of claws.
It is of an olive-brown colour dotted with black, and a black streak
reaching from one end of the body to the termination of the somewhat
thick, short tail.
