66 Mr. W. S. Macleay on certain general Laws regulating 



arrange Annulose Animals in the same way that M. Fries has 

 distributed his Fungi, when it will readily be seen as virtually 

 nothing else than the arrangement I oft'ered to the public in the 

 Hora Entomologies. Thus it is only necessary that instead of 

 subjecting Nature to arbitrary rules of our own invention, we 

 should humbly receive her laws as she clearly proclaims them ; 

 when she will indeed appear, as M. Fries has found her to be, 

 " ubique varia, semper tamen eadem." 



Classification 0/ Annulos a on the same Principles as those adopted 

 by M. Fries in his natural Distribution of Fungi. 



Annulose Animals, which are not hermaphrodite : or the 

 Annulosa of Scaliger may all be divided into two groups 



founded on their larva or foetus state, viz. 

 1. Apterous Insects, having either no metamorphosis in the 

 usual sense of the word, or only that kind of it the ten- 

 dency of which is confined to an increase in the number 

 of feet. 



pf getting their fluids aerated did not the air enter their bodies and penetrate tlirough 

 every part of them. But on this head Desfontaines long since set the scientific world 

 at rest, when he established the relation of Dicotyledonous Plants to Vertebrata, and of 

 Monocotyledonous Plants to Annulosa, not on external appearance merely, but on such 

 primary principles of their respective structures, that we may almost term the former 

 tribe of plants Vertebrated, and the latter Annulose. It would scarcely be fair however 

 towards M.Agardh, did we conceal the fact of his being perfectly aware of the analo- 

 gies which reign both between the Dicotyledonous Plants and the typical group of Fer- 

 tebrata, and between the Fungi and Radiata. With respect to this last analogy, in- 

 deed, the following words are perhaps more explicit than those previously published, 

 p. 211 of the Horn Entomologies — " Fungi superiores animaha Radiata ob figuram 

 radiantem, ob superficiem nudam, ob texturam laxam, ob colorem subsimilem non male 

 revocant."
