animal kingdom ; in that of the Ametahola among the 

 classes of A nn idosu, and of the Coleoptera among the orders 

 of MandihiiUttd. It is a disposition, also, which can 

 scarcely have escaped our notice on examining the genus 

 Fhanceiis, the fifth type of which contains insects re- 

 sembling all the other types, together with. P. carnifex, 

 which has a form peculiar to this fifth type. What 

 this fifth type is to Phanceus, Giimnopleurus is to the 

 genus ScaraheFus ; that is, while it has a form peculiar 

 to itself in G. JJagellntus, it contains insects varying in 

 the structure of those parts which remain constant in 

 the other sub-genera."* 



(2()4.) In the foregoing extracts, we trace tlie first per- 

 ception of that system of representation which we have 

 elsewhere enlarged upon +, and which there is every pre- 

 sumptive evidence to believe exists throughout nature. 

 Not only does one of the five groups contain types of 

 all the rest, together with a form peculiar to itself; but 

 this princijile pervades every natural group, whether 

 large or small. The principle is, undoubtedly, the dis- 

 covery of Mr. MacLeay ; and had he prosecuted his re- 

 searches, and followed the clue thus afforded him^ 

 very little, on this subject, would have been left us 

 to elucidate. This representation, which he supposed 

 to be partial — that is, confined to one only out of the 

 five groups — we have found to be universal, and belong- 

 ing equaUy to the other four. 



(265.) We have been induced to devote more space to 

 the deveiopement of the leading principles of this sys- 

 tem, than we should otherwise have done, on many 

 important accounts. First, because it is unquestionably 

 the first which clearly defined any one philosophic prin- 

 ciple of classification ; so that, strictly speaking, we must 

 date the first partial deveiopement of natural arrange- 

 ment, from the publication of the Horce Entomologicip. 

 Lamarck, it is true, traced theouthnes of the circle, without 

 knowing that he had done so : while Mr. MacLeay,
