which occupies an analogous position, but merely with regard 

 to Orders (viz. the Insectivora, Cheiroptera and Primates) of the 

 Class Mammalia : the Cynopithecus monkey of Celebes, which 

 connects the Genus Macacus with the Genus Cynocephalus, within 

 the limits of the Order Primates. Inasmuch, however, as we are 

 dealing here principally with animals of the Class Mammalia, it 

 follows that the links with which we are concerned will be 

 comparable in point of importance with the two latter examples, 

 rather than with the first-mentioned instance. 



We have seen that the cases of such intermediate forms offers 

 excellent opportunities of employing and testing the principles of 

 morphological examination upon which is based the system of 

 classification here set forth.
