The fish armado is very properly named, for its back and sides are armed all over with very sharp gills and fins, with which it endeavours to wound the fisherman as he is taking the hook from its jaws, horribly roaring at the same time and tossing itself about, on account of which its head must be crushed with a strong stake as soon as it is taken out of the river. Its head is round, resembling that of a frog, and shielded by a very strong shell. It has small bright eyes, surrounded by a circle of gold. Its mouth is narrow, but rendered terrific by a shaggy beard. The body is of an iron-grey colour, and armed with very hard oblong scales. This fish is thicker than it is long, and often weighs four, often six pounds, or more. Its flesh is solid, extremely well tasted, and on that account thought very wholesome for sick persons. The river Paraguay abounds in this noble fish. THE VAGRE. The vagre is a species of trout. Its head is covered with a hard shell, its skin is smooth, slippery, and covered with red spots, and its flesh extremely well tasted. Various rivers contain various kinds of this fish, which are distinguished by the number, size, and colour of their fins and gills, but are all of an admirable savour. Of their bladder, ground with the teeth, and mixed up with brandy, a very strong glue is made. THE SÁVALO. The sávalo somewhat resembles our carp, but is smaller, and more savoury. You scarcely ever see one weighing more than two pounds. This fish is full of thorns. Though very common in many rivers and lakes, it is never caught with a hook. THE BÒGA. The bòga differs little from the sávalo, but is superior to that fish, though less abundant. THE PEJE REY. The peje rey means the king fish, for in fact, though only middle-sized, its flesh is pre-eminently good. It has a very large head and mouth, and is destitute of fat. It is only caught in that part of the Parana which washes the territories of Sta. Fè, or in the kindred streams, to which this fish repairs to spawn. When fresh, it is reckoned amongst the delicacies of the tables of the wealthy. After being dried by the air only, without a grain of salt, it is sent in quantities from the above-mentioned city to others, and kept a long while, but soon putrifies if it contracts any moisture on the way. LA VIEJA. La vieja is a very strange fish, for its whole body is covered with a strong shell, or horny bark, which would resist even a knife. Hence, when caught it is laid on live coals, together with the shell, and eaten roasted in this manner. It is very seldom taken with a hook, and rarely weighs more than a pound. THE DENTUDO.
