Atlantic, between latitudes 5° 25' S. and 29° 30' N., and longitude 

 17°18'W. and 32° 55' W., on the 6th, 12th and 25th of September. 

 It was brilliantly phosphorescent. It is called the Nocticula Ban/csii, 

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

 identical with the Cancer fulgens 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. — From Silliman^s American Journal for July 1850.
