grunt or noise, although of the same class, is decidedly different from that of Maldonado. It is repeated only twice instead of three or four times, it is more distinct, loud, sonorous; it may be compared to the very distant sound of the blows of an axe, cutting down when a small tree is cut down; so close is this resemblance, that I have sometimes remained in doubt for a few minutes. At Bahia Blanca (Lat: 39o) another (or the same) animal makes a similar noise, but repeated at single intervals
