 the heads all gone, and the straw-like tubes only left." 



Lieut. Thomas tells us, in the valuable notes which are 

 published in the Supplement to Johnston's ' History/ that 

 " on the oozy bottom which lies outside a line drawn be- 

 tween Flamborough Head and the Staples " it grows to a 

 very large size. Prof. Forbes found it in Rothsay Bay, 

 flourishing, as it seemed, "upright on a muddy ground 

 like a flower, fixed by the tapering root-like termination 

 of its horny case." In Cornwall, according to Couch, it 

 ranges in height from 2 to 14 inches. Dr. Perceval 

 Wright has found it in remarkable beauty off the west 

 coast of Ireland. Guernsey (A. M. N.).
