sweet fruits, such as the banana, but it is also fond of insects, especially soft-bodied Spiders and 
Grasshoppers, which it will snap up with eagerness when within reach. The expression of countenance 
in these small Monkeys is intelligent and pleasing. This is partly owing to the open facial angle which 
is given as one of 60 ° ; but the quick movements of the head, and the way they have of inclining it on 
one side when their curiosity is excited, contribute very much to give them a knowing expression. 
Anatomists who have dissected species of Midas tell us that the brain is of a very low type, from 
there being few convolutions, the surface being as smooth as that of a Squirrel’s. I should conclude, 
at once, that this character is an unsafe guide in judging on the mental qualities of these animals. In 
mobility of expression of countenance, intelligence, and general manners, these small Monkeys resemble 
DEVlLLE’s MIDAS. (From tlie Proceedings of the Zoological Society.) 
the higher Apes far more than they do any rodent animal with which I am acquainted. On the 
Upper Amazon I once saw a tame individual of the Midas leonvnus , a species first described by 
Humboldt, which was still more playful and intelligent than the one just described. This rare and 
beautiful little Monkey is only seven inches in length, exclusive of the tail. It is named leonvnus on 
account of the long brown mane which depends from the neck, and which gives it very much the 
appearance of a diminutive Lion. In the house where it was kept it was familiar with every one ; its 
greatest pleasure seemed to be to climb about the bodies of different persons who entered. I he first 
time I went in it ran across the room straightway to the chair on which I sat down, and climbed up to 
my shoulder. Arrived there it turned round and looked into my face, showing its little teeth, and 
chattering, as though it would say, ‘ Well, and how do you do V It showed more affection towards its 
master than towards strangers, and would climb up to his head a dozen times in the course of an hour, 
making a great show every time of searching there for certain animalcuhe. Isidore Geoffroy St. Hilaire 
relates of a species of this genus, that it distinguished between different objects depicted on an engraving. 
M. Andouin showed it the portraits of a Cat and a Wasp. At these it became much terrified ; whereas,
