ABSTRACT
The minute creature to which the above name has been given, though abundant, perhaps, in all seas, and noticed so long ago as in the year 1781, has received but little attention from zoologists in general. Its curious and interesting structure, however, and doubtful position in the animal kingdom, render it a subject well worthy of further research ; and its minute size, and the extreme delicacy and transparence of its tissues, make it peculiarly an object of microscopical investigation. Though perhaps unknown, even by sight, to many of our readers, the Sagitta bipunctata will probably be met with on every part of the coast; and it may be procured, without difficulty, at any rate in fine and calm weather, by means of a small muslin towing net over the side of a boat.
