Mingled with the common Egg-Urchin on oyster-beds 

 and scallop-banks is the little species before ns, and pro- 

 bably it is often passed over as the young of Echinus 

 sphara. Its long purple spines, however, at once distin- 

 guish it from the latter in its young state ; and when we 

 examine it more carefully we find that it presents many 

 excellent characters peculiar to itself.
