belly, and in a few minutes he was dead." " The broad 

 ruff round the throat and chin of the Canadian lynx (Felis 

 Canadensis) is much longer in the male than in the fe- 

 male ; but whether it serves as a defence I do not know. 

 Male seals are well known to fight despei-ately together, 

 and the males of certain kinds {Otaria jubatay^ have 

 great manes, while the females have small ones or none. 

 The male baboon of the Cape of Good Hope ( Cynocepha- 

 lus porcarius) has a much longer mane and larger canine 

 teeth than the female ; and the mane probably serves as a 

 protection, for on asking the keepers in the Zoological 

 Gardens, without giving them any clew to my object, 

 whether any of the monkeys especially attacked each 

 other by the nape of the neck, I was answered that this 

 was not the case, excepting with the above baboon. In 

 the Hamadryas baboon, Ehrenberg compares the mane of 

 the adult male to that of a young lion, while in the young 

 of both sexes and in the female the mane is almost absent. 



It appeared to me probable that the immense woolly 

 mane of the male American bison, which reaches almost 

 to the ground, and is much more developed in the males 

 than in the females, served as a protection to them in their 

 terrible battles; but an experienced hunter told Judge 

 Caton that he had never observed any thing which favored 

 this belief. The stallion has a thicker and fuller mane than 

 the mare; and I have made particular inquiries of two 

 great trainers and breeders who have had charge of many 

 entire horses, and am assured that they " invariably en- 

 deavor to seize one another by the neck." It does not, 

 however, follow from the foregoing statements, that when
