BLOUNTIA Walcott, 1916 



Blountia polita, n. sp. 



ArioncUus sp. Walcott, U. S. Geol. Surv. Mon. 32, pt. 2, p. 463, pi. 65, fig. 2, 

 1899. 



Walcott illustrated this pygidium as a cranidium. The artist drew 

 "glabellar" furrows, but when his pencil marks were washed off the 

 specimen, no trace of axial furrows remain. 



B. polita is characterized by its flat lateral profile, and the rather 

 elongate shape due to the lack of narrowing as the j^leural lobes 

 unite behind the axis. The dorsal furrow is shallow, but the axis is 

 marked rather clearly by a change in the profile.
