SIM I A 173 



nected with some group of the great Apes, but the reasons advanced 

 for doing this were faulty, and an error was committed, and no matter 

 how familiar this act may have become to Authors and others generally, 

 yet it was still an error, and therefore something necessary to change 

 and correct. No error can ever become the truth simply by toleration, 

 and should never be continued when discovered for any reason, and 

 particularly not for the totally insufficient one that a change would 

 inconvenience the memories of some writers. It is to be hoped that 

 SiMiA has at length found its true resting place for all time. Mr. 

 Thomas in the same communication, p. 125, advocates that the 

 Macaques should be included in Simia but in this view I cannot agree 

 with him. If the Barbary Ape belongs to a distinct genus, it would 

 naturally be on account of certain attributes possessed by it. Some of 

 these are, the absence of a tail, the peculiar shape of the head, the 

 oblong face, etc., none of which is to be found in any Macaque. The 

 Barbary Ape alone represents the genus Simia, and the Macaques are 

 only properly placed in the genus Pithecus which antedates Macaca 

 (sic), and all other genera proposed for them, and leaves no reason 

 whatever for the employment of any other term.
