1 Verrill's description is so full, and his figures so numerous, that I cannot 

 doubt that his species is the same as that of Prosch, the types of which I had 

 an opportunity of examining in Copenhagen ; and Prof. Sars' beautiful draw- 

 ing leaves equally little room for uncertainty. What Dewhurst's Sepia 

 groenlandica really was will probably always remain unknown, the original 

 description being quite inadequate. 



2 Hutton (Man. Moll. N. Zeal., p. 1) has corrected d'Orbigny's erroneous 

 statement, that this species is from New Zealand ; Quoy and Gaimard say, 

 " le havre Carteret a la nouvelle Irlande."
