 abundant on the coasts of Great Britain. It was first reported 

 from Halifax in 1857, by Mr. John Willis, but Sir William 

 Dawson states that he collected it in the southern part of the 

 Gulf of St. Lawrence earlier than this, and Prof. E. S. Morse 

 received it from Bathurst in 1855. It was found near St. John
