History. — Pirst figured by Parkinson in 1811 ; the test and spines are both well 

 drawn, so that no doubt as to the species intended can exist, although no description of 

 the urchin was given. In 182.2, Mantell figured one of the spines, and gave it the 

 name which it still retains. This species was not indicated in Prance until 1840, when 

 it was entered in M. Agassiz' Catalogus systematica ; since then its test and spines have 

 been found in the localities enumerated above.
