THE RIVER-CRAB.
Although Paraguay abounds in various kinds of choice fish, it is almost destitute of crabs. I had long heard that some very small crabs, not like those of the sea, but like those in the rivers of Germany, were found in certain streams in the territories of the Uruguay; and I myself saw some which were brought to our table in the Uruguayan town of Concepçion; but they were pygmies in comparison with ours, and might be called mere shadows, and embryos of crabs. After travelling, sailing, and fishing so much in Paraguay, as I never saw any other cray fish beside these, it is my opinion that there are none, or very few indeed. But there are a great variety of sea-crabs.
