Very abundant along the shore above and below low-water mark, and 

 on piles of wharves, but always of comparatively small size. A com- 

 parison of the specimens from Provincetown with those obtained from 

 Gloucester in 1878 shows more or less constant diiferences to exist 

 between the two. In the former the spines are generally longer and 

 more acute, sometimes even quite slender, and the pedicellarise appear 

 to be somewhat more numerous, and to vary greatly in their arrange- 

 ment. These differences are, however, of very slight value in this 

 exceedingly variable species.
