models of all the known trilobites, and we trust that the effort of Prof. 

 Green will meet with the encouragement it merits, and be followed 

 up, in Europe, until all the species shall be presented in good models. 

 We regret that our limits do not permit us to extract the descriptions 

 of the new species. The following section forms the conclusion of 

 the work. 



" JVature of the Trilohite. — Every one familiar with the history 

 of the trilobites, is aware that a good deal of controversy has existed 

 among naturalists, respecting the precise link in the grand chain of 

 organized beings, these singular fossil animals, should occupy. Pro- 

 fessor Brongniart, Dr. DeKay, Audouin, and several other acute ob- 

 servers, have placed them in the vicinity of the Limuli, and other 

 Entomostraca with numerous feet ; while P. A. Latreille and others, 

 presuming that these animals were destitute of locomotive organs, 

 as no vestige of them has ever been discovered, fix their natural po- 

 sition in the neighborhood of the Chitones ; or rather that they con- 

 stituted the original stock of the Articulata, being connected on the 

 one hand with these latter Mollusca, and on the other with those first 

 mentioned, and even with the Gloraeris.* It was our original inten- 

 tion to have closed this Monograph with a short history of these the- 

 ories — and of the notion advanced by Latreille and others, that the 

 Trilobites have been annihilated by some ancient revolution of our 

 planet. All these matters, we think, are now put to rest by the late 

 discovery of some living Trilobites in the southern seas, near the 

 Falkland Islands. In the cabinet of the Albany Institute, we have 

 examined some of these recent animals, which have very nearly the 

 size and general appearance of the Paradoxides Boltoni, as repre- 

 sented on our frontispiece ; the species cannot, however, belong to 

 that genus, as the buckler is furnished with eyes very similar to those 

 of the Calymene Bufo ; its organs of locomotion are short, numerous, 

 and concealed under the shell — but I do not feel at liberty to notice 

 the interesting animal more minutely. It will probably be described 

 and figured shortly, in a perfectly full and satisfactory manner, by 

 Dr. James Eights, the enterprising discoverer, together with several 

 other new and remarkable genera and species belonging to the 

 Entomostraca." 



We had the pleasure of seeing the specimens of Dr. Eights of 

 what appear to be recent trilobites. If this opinion is correct, the 

 irilobite must be regarded a being of almost all geological ages.
