ANATOMY OF THE OLFACTORY ORGAN 39 



conchse. Forms that possess these larger numbers of 

 conchae are known to be keen-scented and are termed mac- 

 rosmatic. Those in which the number of olfactory conchae 

 is small, four or fewer, such as the seals, some whales, 

 monkeys, and man, are known to be less acute of smell 

 and are called microsmatic. Others again, such as the 

 toothed whales, porpoises and the like, in which the olfac- 

 tory organ has almost completely degenerated, are sup- 

 posed to be devoid of olfaction and are called anosmatic. 

 In such forms the nasal cavities have lost their original 

 sensory function and have come to be of importance only 

 in connection with respiration, a purely secondary relation.
