5. Pentelasmis anatifera, Leach. Lepas anatifera, Lin. Anatifa 

 laevis, Lamarck. Adhering to a plank of wood cast on shore in the 

 winter 1819-20. This is the shell which, little more than a century ago, 

 was generally believed to be the embryo of the barnacle duck ; and, in 

 the year above mentioned, I had the tale told me by our fishermen, yet, it 

 must be allowed, in a manner that showed they were very incredulous 

 of a fable, to the truth of which very learned historians and theologians, 

 and very observant naturalists, have deponed with the confidence and 

 sincerity of eye-witnesses. 



6. Scalpellum vulgare, Leach. Lepas scalpellum, Lin. Pollicipes 

 scalpellum, Lamarck* On corallines, especially on Tubularia ramosa, 

 not uncommon.
