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. The _Piráuh_ and _Piába_, of both of which I have already spoken, are as abundant here as they are below the Falls of Paulo Affonso; besides these, there must be many others which I had not an opportunity of seeing. During the whole time we remained in San Romão, we lived principally on fish; indeed, it is so abundant and so cheap, that fresh beef is rarely offered in the market. The navigation of the river being uninterrupted from this place to the Falls of Paulo Affonso, many canoes are continually passing up and down; their principal cargo up is salt, from the manufactories which exist on the vast saline flats on both sides of the river below Porto do Salgado; this is partly sold for money, and partly exchanged for hides, tobacco, &c.
