known species of the genus, and the posterior projection into a spine is 

 also unlike, while the caudal extremity and character of surface sculp- 

 ture are all closely like the asaphus; 



We shall probably soon be able to have perfect specimens, and as it 

 will prove an interesting species, perhaps this notice may attract atten- 

 tion and excite examination among those living in the neighborhood of 

 the localities where this species has been found. 



It is not improbable but the middle lobe of a buckler described (Pal. 

 N. Y., vol. i., page 248, pi. 61, fig. 1, a, b,) as Asaphus nodostriatus, may 

 prove to belong to this species, but the same part of the fossil here flg- 

 gufed does not preserve the surface markings to enable us to make the 

 comparison. (State Collection,)
