444 NEW GENERA AND SPECIES OF CAMBRIAN FOSSILS. 



shales of Coosa Valley, near Blaine post office, Cherokee County, Ala. r 

 where it occurs on the surface of dark flint nodules. 



Oleuoides curti^ei. 

 Olenoides sp. nndet. 



A second species of Oleuoides was found by Dr. Curtice in an argil- 

 laceous shale, on the Edward's farm, near Craig's Mountain, Cherokee 

 County, Ala. It differs, in the parts available for comparison, from 0. 

 curticei in having a larger number of spines on the margin of the pygi- 

 dium, and the posterolateral limb of the head is shorter back of the eye. 



The pygidium is much like that of 0. nevadtnsis, but, until more per- 

 fect specimens are obtained, I will not attempt to name or compare the 

 species. 



The associated fossils are Lingulella (?), Acrotreta, Scenella, Steno- 

 theca, Hyolithes, aud Ptychoparia three sp., etc.
