Bibliographical History. Linnaeus, in his ' Wastogota 

 Resa,' or tour through Westrogotha in 1747, describes a 

 species of Lernea, which he aftenvards named Lerntea 

 asettina, that evidently belongs to the family of Chondro- 

 canthidse. This is the first notice of any species that we 

 have met with, but the figure is too indifferently executed 

 to enable us very distinctly to refer it to any one de- 

 scribed. Barbut, in his ' Genera Vermium,' 1703, copies 

 the figure as it is, and mentions it as the Lernea that 

 infests the gills of the cod and ling of the Northern 

 Ocean. Miiller, in his ' ZoologiaDanica,' 1781, describes 

 and figures three other species infesting the fishes of the 

 Danish seas, two found on soles, and a third on the Cory- 

 pliaena rupestris. Delaroche, in the ' Nouv. Bull, des Sc. 

 de la Soc. Philom.,' 1811, describes another species, and
