below the Lower Carboniferous rocks which overlie them unéonforma-

Period, and the zealous researches, more especially of Mr. Hartt, have 
brought to light no less than forty to fifty species, or half of the whole 
number known in the Devonian of Eastern America, as well as six 
der.* These insects are the first ever found in rocks older than the 
Carboniferous.

Paradozides, vraag and Agnostus, as well as an Orthis, and a new
