marks on several Polypi, &c., found in Massachusetts Bay ; by Jo- 
sePpx P. Covrnovy. From the Journal of the Boston Soc. Nat. 
Hist. Vol. 11. 
We are pleased to see so much critical knowledge and laborious re- 
search brought to bear on the shells and polyps of our coast, as is 
evinced in thé article before us. Its zealous author has discovered 
nearly all the shells herein described, in the entrails of the sea fish, 
brought to the Boston market. 
The following are the short specific descriptions of the new species; 
we have not space to copy the remarks or figures which accompany 
them. Massachusetts Bay is the locality of the species, when not 
otherwise stated.
