Bates, (1. c.) says he once saw a tame individual of M. leoninus = 

 L. rosalia?, which was even more playful and intelligent than (M.) 

 Ursula. In length of body it measured only seven inches, and was 

 friendly with every one in the house where it lived, and its greatest 

 pleasure was to climb about the persons of those who entered. When 

 he first visited the house, it ran to the chair on which he was sitting 

 and climbed on to his shoulder, and looking into his face showed its 

 teeth and chattered as though it would say, "Well, and how do you do ?" 

 It was very affectionate with its master and would climb upon his head a 

 dozen times in an hour, and make a great show of searching for certain 

 animalculae. Of this species Isidore Geoffroy Saint-Hilaire knew of 

 one individual that distinguished between different objects in an 

 engraving. When shown figures of a cat and wasp, it was very much 

 frightened, but when it saw a grasshopper or beetle, it precipitated 

 itself on the picture and tried to seize them.
