 as it is supposed by Thompson, and with apparent good reason, to be 

 identical with the Cancer fulg ens of Sir Joseph Banks, a species ob- 

 served between Madeira and Brazil, and published with a drawing by 

 Macartney in the Philosophical Transactions for 1810. This draw- 

 ing Thompson has copied, and in it seven pairs of thoracic legs are 

 represented. — Fro^n Silliman's American Journal for July 1850.
