phaga jubata, L., (Yurumi); and 55. Myrm. tridactyla, L., (Ca-

Under the head of the Horse, the authour gives many interesting parti- 
culars relative to the half wild race, which has extended itself so won- 
derfully over the plains of this and the neighbouring parts of South 
America. Seven Ruminantia complete the catalogue: they are: 62. 
Cervus paludosus, Desm., (Guazu-pucu) ; 63. Cerv. campestris, F. 
Cuv., (Guazu-y) ; 64. Cerv. rufus, F. Cuv., (Guazu-pyta); 65. 
Cerv. simplicicornis, Illig., (Guazu-vira); 66. Bos Taurus, L.; 67.

ability, and much scientific information; but we regret that we cannot 
afford space for their analysis. They add much to the value of this 
interesting work,

and of the philosophical spirit in which his investigations were con-
