of fresh-M'ater lakes and rivers. Kear Maldonado three or 

 four generally live togetlier. In the daytime they either lie 

 among- the aquatic plants, or openly feed on the turf plain.* 

 "When viewed at a distance, from their manner of walking 

 and colour they resemble pigs : ])ut when seated on their 

 haunches, and attentively watching any object with one eye, 

 they reassume the appearance of iheir congeners, cavies and 

 rabbits. Both the front and side vi<nv of their liead has quite 

 a ludicrous aspect, from the great depth of their jaw. Tiiese 

 animals, at Maldonado, were very lame ; by cautiously walk- 

 ing, I approachetl within three yards of four old ones. This 

 tameness may probably be accounted for, by the Jaguar having 

 been banished for some years, and by the Gaucho not thinking 

 it worth his while to hunt them. As I approached nearer and 

 nearer they frequently made their peculiar noise, which is a low 

 abrupt grunt, not having much actual sound, but rather arising 

 from the sudden expulsion of air: the only noise I know at all 

 like it, is the first hoarse bark of a large dog. Having watched 

 the four from almost within arm's length (and they me) for 

 several minutes, they rushed into the water at full gallop with 

 the greatest impetuosity, and emitted at the same time their 

 bark. After diving a short distance they came again to the 

 surface, but only just ishcwod the upper part of their heads. 

 AVhen the female is swimming in tlie water, and has young ones, 

 they are said to sit on her back. These animals are easily killed 

 in numbers; but their skins are of triHing value, and the meat is 

 very indifferent. On the islands in the Rio Parana they are 

 exceedingly abimdant, and afford the ordinary prey to the 

 Jaguar. 



The Tucutuco (Ctenomys Brasiliensis) is a curious small 

 animal, which may be briefly described as a Gnawer, with the 

 liabits of a mole. It is extremely numerous in some parts of the 

 country, but is difficult to be procured, and never, I believe, 

 comes out of the ground. It throws up at the mouth of its 



* In the stomach and dnodennm of a capybara -which I opened, I found a 

 very large quantity of a thin yellowish fluid, in which scarcely a fibre could 

 be disthiguished. Mr. Owen informs me that a part of the ces )) hagns is so 

 constructed that nothing much larger than a crowquill can be passed down. 

 Ceitainly the broad teeth and strong jaws of this animal are well fitted to 

 grind into puip the aquatic plants on fyhich it feeds.
