The author compares them with Apus and other Aspidophora, animals 

 which, in his opinion, of all the Entomostraca, appear to come nearest to 

 the Trilobita.

The author remarks that "it is evident from the new specimen of Ellip- 

 tocephalus asaphoides from the shales of Washington county, N. Y., figured 

 in Emmqn's American Geol., pi. 1, fig. 18, that this trilobite is a Paradox- 

 ides related to the group of P. spinosus, perhaps identical with the P. 

 harlani of Braintree. Besides, the trilobite figured pi. 1, fig. 16, and 

 called Atops trilinealus, is a true Sao, which genus is the most character- 

 istip of the primordial fauna of Bohemia and Scandinavia."
