Loiver and Middle Taconic. — Marcou. 373 
but it will take many years for it. As a resume of the inferior 
part of the true Primordial fauna or fauna of the Scandi- 
navian formation, we have a total of 17 species for Europe and 
25 or 30 for Newfoundland ; in all 47 species. 
IV. Bohemian formation or Paradoxides Zone. — The first 
fossils special to this zone were found by Dr. Emmons, and 
published by him as far back as 1844. They were two trilo- 
bites ^to])s trilineatus and Elliptocephala asaphoides found near 
Bald mountain in eastern New York. To the great credit of Dr. 
Emmons he saw that the few fossils which he was able to 
gather, were special and characteristic of the series of strata, 
which he called Taconic System, below the Lower Silurian of 
Murchison, or Cambrian of Sedgwick. Barrande, without 
knowing the discovery of Emmons, described in 1846, the pri- 
mordial fauna of Bohemia, showing its complete independence 
and its absolute difference from the second fauna. (Notice 
preliminaire sur le systeme Silurien et les trilobites de Bo- 
heme", pp. 8-22, Leipzic). 
As soon as Barrande was able to consult Emmons' publica- 
tions, which did not reach him until 1860, he at once recog- 
onized the priority of the discovery of Emmons, and estab- 
lished on the most solid basis, the just claim of America, to 
the honor of naming the great series of strata below the sec- 
ond fauna or Champlain system, called Lower Silurian system 
in England by Murchison and Cambrian system by Sedgwick. 
If justice and honesty are in favor of using in the general 
classification of the world, the name Taconic system, it is 
right also to recognize that Barrande is the first who gave their 
full value to the fossil remains existing in that great special 
system, calling them, primordial fauna, and that his studies 
in Bohemia, truly created the primordial fauna. Barrande al- 
so, first of all showed the great value of the genus Paradoxides, 
in recognizing the existence of his primordial fauna, and con- 
sequently we are justified in consecrating the name Bohemian 
formation or Faradoxides zone, to designate that great and prin- 
cipal division of the Middle Taconic, in honor of Barrande and 
his splendid discoveries and Avork on the fauna of Ginetz and 
Skrey. 
Bohemia. — After many years of very careful researches, Bar- 
rande found only 40 species of Primordial fossils at Skrey and 
Ginetz,the only two fossiliferous localities of the Bohemian basin.
