1 Op. cit, p. 543. As I did not feel justified in removing the huccal organs from the small solitary specimen of 

 Amphitretus pelagicus in the collection, I am imable to say whether it belongs to the Traehyglossa or the Lioglossa. 



^ Having had no opportunity of forming an independent opinion as to the values of the various recorded species 

 of Argonaut, I have followed von Martens {Ann. and Mag. Nat. Hist, ser. 3, vol. xx. p. 103, 1867), and added such 

 other species as have been described since the publication of that paper. 



' I have been unable to ascertain beyond doubt when this was published, for the volume bears no date. Dillwyn 

 {op. cit., p. xi.) gives 1790 ; if this be correct Solander's name should take precedence.
