 crouch motionless, the eyes flashing and tail waved 

 from side to side ; finally, the rush and spring, when 

 the playfellow is captured, rolled over on his back

 many of the cats may be mentioned, also dogs and 

 foxes, capybaras and other loquacious rodents ; and 

 in the howling monkeys this kind of performance 

 rises to the sublime uproar of the tropical forest at

 and beautiful motions, and with melody. But every 

 species, or group of species, has its own inherited 

 form or style of performance ; and, however rude 

 and irregular this may be, as in the case of the pre-
