3. Dourádo.—A beautiful fish, from two to four feet in length; it is generally taken with the hook, but is not considered delicate food. We, nevertheless, relished the first we ate very much, it being this species I bought of the boy on the day we arrived at San Romão.
4. Matrixám.—Somewhat similar to the Dourádo, but smaller, and considered a much superior fish.
5. Piau branco.—From one to two feet long, and with much larger scales than any of the others; it is taken with the hook, and its flesh is much esteemed.
6. Curvínha.—About two feet in length, with a scaly head; it takes the bait readily, but the flesh, which is soft, is not considered good.
7. Traíra.—Also about two feet long and rather slender; it takes the bait, and is much esteemed.
8. Pirá.—About two and a half feet long, with a protruded beak; is only taken with the drag-net, and is considered a delicate fish.
9. Mandí.—One of the Siluridæ, and perhaps a species of Mystus; from a foot and a half to two feet long, with no apparent scales, and long barbecels proceeding backwards from its mouth. It keeps near the bottom of the river, is taken by the hook, and considered one of the best fish it produces.
10. Pocomó.—This and the following also belong to the Siluridæ, and are, perhaps, species of the genus Hypostomus. The Pocomó is an ugly black fish, about two feet long, covered with large hard plates. It keeps near the bottom, and is taken in great plenty in the nets which are thrown for other fish. During my visit, the sandy shores of the river were covered with those which had been thrown out of the nets. It is seldom eaten, but makes good bait for other fish.
11. Cascuda.—This species is smaller than the last, and very much resembles it, except that it is of a yellow colour.
