Vast numbers were found on the West Sands, after a 

 severe storm, in January 1867. They were scattered amidst the 

 foam on the beach along with multitudes of Plwrobrachia ; 

 and it is curious that very little else was cast ashore at this 

 time. The season is remarkable, as Prof. Busk, who is the 

 author of a most valuable paper* on the structure and rela- 

 tions of the animal, thought it would chiefly be procured in 

 fine and calm weather in the towing-net. They were re- 

 cognized by the active movements of their bodies, which 

 glistened all along the beach like needles of glass.
