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 differences to exist 
between the two. In the former the spines are generally longer and 
more acute, sometimes even quite sleuder, and the pedicellarie 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.
