NOTE ON LOWP]R CAMBRIAN FOSSILS FROM 

 COHASSETT, MASS.* 



BY CHAS. D. WALCOTT. 



In a l)o\vl(k'i- of reddish-l>ruwn limestone, pieked up l>y Mr. 

 T. A. Watson on Pleasant Beach, Cohassett, Mass., and for- 

 warded to me for examination by Dr. W. O. Crosby, I found 

 two species of Lower Cambrian fossils — Straparollina reinota 

 Billings, and Hyolithcs communis Billings. The original speci- 

 mens of Straparollina remota Avere found in Smith's Sound, 

 Trinity Bay, Newfoundland, in rocks of Lower Camln-ian age. 

 This species is very closely allied to Plearotomaria {Baphidoma) 

 attleborovjjhensis, Shaler & Foerste from Attleborough, INIass. 

 The same slender species of HyoUthes also occurs associated 

 with the Attleborough form. 



It is interesting to note the occurrence of Cambrian fossils in 

 eastern Massachusetts, as every discovery of a species identical 

 witli the fauna of Newfoundland strengthens the correlation 

 between the two sections.
