From Massachusetts Bay to the Arctic Ocean ; Northern Europe ;

At Grand Menan, below low-water, among Nullipora, frequent, 

 Stimpson. I have dredged it sparingly at Eastport, Me., in twenty 

 fathoms, shelly bottom.

This beautiful and variously colored species* ranges from Vineyard 

 Sound and Cape Cod, Mass., to the Arctic Ocean, and on the coast of 

 Europe from Spitzbergen southward to Denmark and Great Britain. 

 I have found it abundant in Massachusetts Bay, and at Mt. Desert, 

 Me. At Eastport, Me., and Grand Menan, I have obtained it in 

 great numbers among stones, Nullipora and sponges, at low-water of 

 spring tides, and dredged it i:ilentifully in fifteen to twenty fathoms, 

 rocky bottom, among Nullipora, sponges, Ascidia, Boltenia, etc. Cod- 

 fish devour great numbers of them.

From Cape Cod to Gaspe, Canada East. From low-water to 

 thirty-five fathoms ; Boston Harbor, of large size, Mr. Kilby Paige 

 (Coll. this Soc.) ; Cape Cod, Capt. N. E. Atwood. I have obtained 

 it at Grand Menan in tliirty fathoms ; at Eastport, Me., at low-water 

 of spring tides among rocks (mostly small specimens), and abundantly, 

 of all sizes from half an inch to eighteen inches or more in diameter, 

 in fifteen to twenty fathoms, shelly and stony bottom. The very 

 young ones were mostly clinging to the branches of Alcyonium car- 

 neum Ag. It is often iDrought up on fish lines. 



* It seems unnecessary to supplant the name (aculeata) given to this species by 

 Retzius, in 1783, and Miiller, in 1789, by bellis, which was given in 1733 by 

 Linck, before the binomial system was estabUshed, and not as a part of a bino- 

 mial name. The former appears to have priority under the binomial system.
